IBM InterConnect: Java vs JavaScript for Enterprise WebAppsChris Bailey
The last few years have see a huge growth in the usage of JavaScript, to the extent that it is often reported to be the #1 programming language in use today. Additionally, the arrival of server-side JavaScript through frameworks such as Node.js and Ringo.js, and JavaScript on the JVM through Nashorn and Avatar.js, mean that enterprise web applications written in JavaScript are not just a possibility—but a reality for companies such as LinkedIn, eBay, Yahoo, ADP and Dow Jones. This session will compare and contrast the two platforms and describe the advantages of each for deploying, managing and monitoring highly scalable applications. It will also introduce IBM's strategy for building a common ecosystem around the two languages.

FLOW3 is an application framework which will change the way you code PHP. It aims to back up developers with security and infrastructure while they focus on the application logic.
FLOW3 is one of the first application frameworks to choose Domain-Driven Design as its major underlying concept. This approach makes FLOW3 easy to learn and at the same time clean and flexible for even complex projects. Built with PHP 5.3 in mind from the beginning, it features namespaces and has an emphasis on clean, object-oriented code.
Thanks to its Doctrine 2 integration, FLOW3 gives you access to a wide range of databases while letting you forget the fact that you’re using a database at all (think objects, not tables). FLOW3’s unique way of supporting Dependency Injection (no configuration necessary) lets you truly enjoy creating a stable and easy-to-test application architecture. Being the only Aspect-Oriented Programming capable PHP framework, FLOW3 allows you to cleanly separate cross cutting concerns like security from your main application logic.
In this tutorial we’ll walk you through an imaginary project from scratch. During the journey we’ll visit all important areas of the framework like templating, routing, security and persistence. For every core concept we’ll provide a short introduction, so that the process is comprehensible to all experienced PHP developers.
Presentation from JVMLS 2015
One bottleneck in the Nashorn JavaScript engine is startup time. Nashorn, as it works currently in Java 8, JITs everything to Java bytecode, accruing overhead in code generation and class installation. Nashorn in Java 9, can in unfortunate cases, increase this compilation workload significantly, as the new optimistic type system, which has greatly increased steady state performance, requires more code invalidation on warmup. Based on our optimistic type compilation framework, which contains all the mechanisms for quick code replacement and on stack replacement on the bytecode level, I will present the new execution architecture we are developing. It will minimizes compile time intelligently, while maintaining or possible even increasing code performance, due to extra profiling and execution frequency information being passed to the JIT. I will also talk about what the future will bring in terms of other dynamic languages on the Nashorn engine, partial method compilation of hot paths and other intriguing possibilities that our new execution model opens up.
Are you tired of java.lang.OutOfMemoryError: PermGen space? Then this talk is for you! We'll begin with a crash course in the Java memory model in order to understand what the error message means. Then we'll look at different causes of the error and how to avoid them. We may glance at a few interesting mistakes from the Open Source world. Last but not least you'll learn how you can get rid of java.lang.OutOfMemoryError: PermGen space once and for all.
Advanced AV Foundation (CocoaConf, Aug '11)Chris Adamson
The iOS version of iMovie uses the AV Foundation framework, and indications are that Final Cut Pro X will be using the Mac OS X version of AVF. And if AV Foundation is powerful enough to provide the core functionality of Final Cut, it must have some great stuff going on, right? In this session, we'll dig into the more powerful (and more challenging) APIs in AV Foundation, including reading and writing raw samples, performing live processing of incoming data at capture time, and advanced editing features like mixing audio and video tracks and adding Core Animation-based titles.
In this talk, Damien describes the infrastructure Nuxeo has built around Docker containers, which is mainly based on CoreOS and Docker, and how it provides a way to generically run applications not only on a single host, but across a whole cluster of hosts. The resulting architecture can be used to implement a PaaS approach for any application.

The main body of work related to supporting dynamic languages on the JVM at Oracle today is done within the Nashorn project. While on the surface it looks like we're busy creating a JavaScript runtime, in reality JavaScript is only the beginning, and not the ultimate goal. Nashorn has served as the proving ground for new approaches for implementing a dynamic language on top of the JVM, and we're eager to – once solidified – crystallize these into a reusable dynamic language implementer's toolkit. We have faced challenges of optimally mapping JavaScript local variables to JVM types (or: "hey, there's a static type inference algorithm in your dynamic language compiler"), doing liveness analysis, cutting up methods too large to fit into a single JVM method, efficiently representing large array and object literals in compiled code, creating a system for on-demand compilation of several type-specialized variants of the same function, and more. Along the way, we have reached the limits of our initial internal representation (fun fact: you can't do liveness analysis on an AST. We learned it the hard way.) and started sketching up an intermediate representation that would be easy to emit from a dynamic language compiler, and that could be taken over by a toolchain to perform the operations described above then on it and finally output standard Java bytecode for JIT to take over. Elevator pitch: like LLVM, but for dynamic languages on the JVM.
Efficient Memory and Thread Management in Highly Parallel Java Applicationspkoza
This presentation discusses strategies to estimate and control the memory use of multi-threaded java applications. It includes a quick overview of how the JVM uses memory, followed by techniques to estimate the memory usage of various types of objects during testing. This knowledge is then used as the basis for a runtime scheme to estimate and control the memory use of multiple threads. The final part of the presentation describes how to implement robust handling for unchecked exceptions, especially Out Of Memory (OOM) errors, and how to ensure threads stop properly when unexpected events occur.
It is easy to monitor the performance of JVM if one knows how GC and Threads work in JVM. This presentation throws light on Collector types, HotSpot Collection Algorithms, Thread Monitoring, Method Profiling and Heap Profiling
WebSphere Technical University: Top WebSphere Problem Determination FeaturesChris Bailey
Problem determination is an important focus area in the IBM WebSphere Application Server. Serviceability improvements have been added that have greatly improved the ability to find root causes of problems in both the full IBM WebSphere Application Server profile, and the newer Liberty profile. The session focuses on how to effectively use serviceability improvements added to the application server since V8.0. This includes high performance extensibe logging, cross-component trace, IBM Support Assistant data collector, timed operations, memory leak detection/prevention, and IBM Support Assistant 5.
Presented at the WebSphere Technical University 2014, Dusseldorf
Native out-of-memory errors happen when a Java application runs out of memory, not in the Java object heap but outside it. The cause may be memory use for native libraries, class loading, multithreading, working data for the Java VM, backing storage for Java objects, or other reasons. No single tool can give you all the answers, and we need to cross-reference information from multiple sources to isolate a problem. Operating system tools, Java dumps, logs, and debuggers all provide useful perspectives, and your challenge is to line them up to see the whole picture. This session works through the tools and data available on the main server platforms to give you a repeatable framework for native out-of-memory error debug.

Programmers are often advised to use “the right tool for the right job.” So how does Java compare to JavaScript? This session compares and contrasts Java and JavaScript in different areas and determines just which is the king of the languages that start with Java.
This talk will present an overview of shared-memory heterogeneous ( accelerated ) computing starting with the Cell Broadband Engine used in the Playstation 3 and the world's first 1 Petaflop supercomputer in 2008, to the current number 1 and 2 supercomputers: Summit and Sierra a decade later that combine POWER processors and NVIDIA GPUs in a high-bandwidth shared-memory configuration. We examine the architectural foundations, and we show the benefits of this architecture in a number of different computing domains, from HPC applications to Big Data and ML/DL for AI. We also spend time discussing FPGAs connected to the host processor in a shared-memory configuration and the recent developments in shared-memory programming for such systems.
From Java Code to Java Heap: Understanding the Memory Usage of Your App - Ch...jaxLondonConference
Presented at JAX London 2013
When you write and run Java code, the JVM makes several allocations on your behalf, but do you have an understanding of how much that is? This session provides insight into the memory usage of Java code, covering the memory overhead of putting int into an integer object and the cost of object delegation and the memory efficiency of the different collection types. It also gives you an understanding of the off-Java (native) heap memory usage of some types of Java objects, such as threads and sockets.

A Java Implementer's Guide to Boosting Apache Spark Performance by Tim Ellison.J On The Beach
Apache Spark has rocked the big data landscape, quickly becoming the largest open source big data community with over 750 contributors from more than 200 organizations. Spark's core tenants of speed, ease of use, and its unified programming model fit neatly with the high performance, scalable, and manageable characteristics of modern Java runtimes. In this talk we introduce the Spark programming model, and describe some unique Java runtime capabilities in the JIT, fast networking, serialization techniques, and GPU off-loading that deliver the ultimate big data platform for solving business problems. We will show how solutions, previously infeasible with regular Java programming, become possible with a high performance Spark core runtime, enabling you to solve problems smarter and faster.
The IBM Java implementation is now virtualization aware! In modern data centres, highly virtualized systems produce a challenge for traditional Java implementations and applications designed for static systems. The IBM JVM exposes Virtualization and OS related information through a set of MXBeans. This session talks about the newly added APIs and the use cases to better optimize the JVM in the cloud.
This talk presents a number of opportunities to tune the JVM (virtualization info in javacore, JIT idle tuning etc) and also for a way to tune the middleware virtualized environments.
Learn about the Virtualization aware JVM and explore the ways to exploit this information to optimize your application for the cloud.

ODA Backup Restore Utility & ODA Rescue Live DiskRuggero Citton
When applying maintenance to Oracle Database Appliance, it's best practice to back up the ODA system environment (local system boot disk). DBAs have procedures to backup and recover the database but it is also important that you are able to backup and recover the environment that runs the database. This is especially useful if you encounter an issue during patching; you can quickly restore the system disk back to the pre-patch state.
Function-as-a-Service (FaaS) and serverless platforms increase productivity by enabling you to focus on application code, with the platform taking care of how to deploy, configure, run and scale the code. They do however require you to adopt a new programming model, writing simple JavaScript functions or actions instead of using the expressive APIs that are available from Express.js, Hapi.js, Fastify, and other frameworks.
In this session, you’ll learn how it's now possible to create FaaS and serverless based applications using the same framework APIs that you use today, and see a live demo of an application being built and deployed as a serverless cloud native application on Kubernetes.
Voxxed Micro-services: Serverless JakartaEE - JAX-RS comes to FaaSChris Bailey
Function-as-a-service (FaaS) and serverless platforms increase productivity, enabling you to focus on application code, with the platform taking care of how to deploy, configure, run, and scale the code. They do however require you to adopt a new programming model, creating generic handlers or actions that lack the expressive APIs that you get from frameworks and standards such as Jakarta EE. In this session, you’ll learn how it’s now possible to create FaaS- and serverless-based applications using the same APIs you use today such as JAX-RS and you’ll see a live demo of an application being built and deployed as a cloud native application on Kubernetes using a combination of open source tools and Knative serving.
Silicon Valley Code Camp 2019 - Reaching the Cloud Native WorldChris Bailey
The move to microservices enables developers to rapidly create and innovate by giving them autonomy to build and deploy applications using the languages, frameworks and technologies that they choose. However, such move requires a cost. Developers require a deeper set of skills to create apps that integrate fully with cloud-native capabilities. The additional complexity is one of the main reasons why most “cloud applications” are co-hosted. Only 38% of cloud developers are leveraging cloud services, and just 12% are building cloud-native applications. These statistics indicate that the majority of applications do not fully leverage and integrate with the additional capabilities that the platform provides. This session will introduce you how to modernize existing and build new cloud-native applications, and show how to utilize open source tools to rapidly develop and build new cloud-native applications with best practises built-in.

The Kitura Server-side Swift framework has built support for Swagger and OpenAPI directly into its framework so that it auto-generates its own OpenAPI specification. This presentation show's how that enables Kitura to be used in the much wider OpenAPI ecosystem.
The fundamental performance characteristics of Node.js make it ideal for building highly performant microservices for a number of workloads. Translating that into highly responsive, scalable solutions however is still far from easy. This session will not just discuss why Node.js is a natural fit for microservices, but will introduce you to the tools and best practices for creating, building, deploying, monitoring and tracing microservices that are both scalable and fault tolerant, and show through a live demo how do that with minimal effort.
Speakers:
Chris Bailey, Chief Architect, Cloud Native Runtimes, IBM
Beth Griggs, Node.js Developer, IBM
There are an emerging set of architectures that are designed to optimise how front-end applications access back-end services, the most popular of which are the Backend-For-Frontend (BFF) pattern and the use of GraphQL. The BFF pattern takes the approach that the backend should be bespoke to the front-end it serves, optimised for that front-end, and ideally owned by the front-end team. GraphQL however sits at the other end of the spectrum: providing an optimised but utility backend for all frontends that is agnostic of the clients it serves. Give the two very different approaches, which is the right approach to take? This sessions will introduce the two approaches, highlight their advantages and disadvantages, and help you determine which you should be looking to adopt as the backend technology for your frontend applications.
Swift Cloud Workshop - Swift MicroservicesChris Bailey
How to deploy Swift micro-services using Docker and Kubernetes, with scaling, monitoring and fault tolerance using the Kitura server side Swift framework.
Swift Cloud Workshop - Codable, the key to Fullstack SwiftChris Bailey
Codable, introduced in Swift 4, makes is possible to share Swift classes and structs between client and server, making it easy to share data. It can also be used to add such more type safety to other parts of Fullstack Swift. This presentations shows some of the many ways that Codable is being using in Kitura to enable Fullstack Swift.
Try!Swift India 2017: All you need is SwiftChris Bailey
In September last year Swift 3 was released, added official support for Swift on Linux for the first time. This provided the scope for Swift to be used for both front-end and back-end development, allowing iOS developers to gain the benefits of full-stack development that Web developers have enjoyed for some time. In just twelve months, this has moved from promise to reality, with full-stack Swift applications not just being possible but being developed and deployed by some of the largest companies in the world.
In this session Chris and AB will introduce you to full-stack Swift development, show you how easy it is to get started, and talk about how the IBM MobileFirst for iOS Garage are building full-stack Swift applications their customers.
Swift Summit 2017: Server Swift State of the UnionChris Bailey
Server Swift has come a long way in the last 12 months, reaching a point where there are multiple successful frameworks and clouds. This session reviews the last year, announces some new capabilities, and outlines some of what to expect in the (near) future.
Node Interactive: Node.js Performance and Highly Scalable Micro-ServicesChris Bailey
The fundamental performance characteristics of Node.js, along with the improvements driven through the community benchmarking workgroup, makes Node.js ideal for highly performing micro-service workloads. Translating that into highly responsive, scalable solutions however is still far from easy. This session will discuss why Node.js is right for micro-services, introduce the best practices for building scalable deployments, and show you how to monitor and profile your applications to identify and resolve performance bottlenecks.
For just over a year, Swift has been available as a formal release on Linux and frameworks like Kitura and Vapor have made it possible to build mobile backends and web applications on the server. Running Server Swift is however not your own option for becoming a fullstack engineer and building backends in Swift. Amazon, Microsoft, Google, IBM and others are all also providing the ability to run Serverless (aka Lambdas or Functions), with some of those supporting the use of Swift.
This session will introduce you to Serverless Swift, highlight how it compares to Server Swift and show you some applications that have been built with Server(less) Swift.
AltConf 2017: Full Stack Swift in 30 MinutesChris Bailey
The introduction of Swift on the server gave the promise of being able to easily build, deliver and own the whole user experience and the solution, not just the iOS app. Building a backend however introduces many new technologies and terms, from server, cloud and Swagger definitions, to Docker and Kubernetes. This session will show you how easy it can be, demonstrating how to build a Swift Server application and connect to it from an iOS app in under 30 minutes.
InterConnect: Server Side Swift for Java DevelopersChris Bailey
The range of languages and frameworks that are available for building server applications has exploded over the last few years, with the most recent of these being the Swift programming language, which IBM has been backing along with the Kitura application framework. But does this mean that Swift is the future and you should stop developing Java server applications? This session will give you an introduction to where and when you might use Kitura, and take you through the experiences of a long-time Java EE developer building their first Angular.js based Kitura application, and how that compares to building the same application with IBM WebSphere Liberty.
InterConnect: Java, Node.js and Swift - Which, Why and WhenChris Bailey
Java, Node.js, and Swift are three of the most popular and effective programming languages in use today. When presented with an opportunity to choose, it may not be clear which language is best suited for the job. This session will provide a tour of these languages and the use cases for which each is best suited.
Over the last 12 months Swift has gone from an emerging language on the server, to a real one. The ability to run Swift on both Mobile and Server, works ideally in the Backend for Frontend "BFF") pattern.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs.

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

Innovating Inference - Remote Triggering of Large Language Models on HPC Clus...Globus
Large Language Models (LLMs) are currently the center of attention in the tech world, particularly for their potential to advance research. In this presentation, we'll explore a straightforward and effective method for quickly initiating inference runs on supercomputers using the vLLM tool with Globus Compute, specifically on the Polaris system at ALCF. We'll begin by briefly discussing the popularity and applications of LLMs in various fields. Following this, we will introduce the vLLM tool, and explain how it integrates with Globus Compute to efficiently manage LLM operations on Polaris. Attendees will learn the practical aspects of setting up and remotely triggering LLMs from local machines, focusing on ease of use and efficiency. This talk is ideal for researchers and practitioners looking to leverage the power of LLMs in their work, offering a clear guide to harnessing supercomputing resources for quick and effective LLM inference.
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
