This session covers the basic mechanics of WebAssembly—what does it look like, how do you create one, and how do you run it?—and shows some examples of the newest, coolest server-side use cases. The aim will be to run untrusted code (a user-defined function) in a Spring Boot application, enabling the application and its deployment to be completely separated from the business logic. In a true serverless fashion, the application becomes the platform. It will be demonstrated that there are immediate uses for such a pattern in Spring Cloud Data Flow and Spring Cloud Gateway.
Go debugging and troubleshooting tips - from real life lessons at SignalFxSignalFx
Exploring tips and advice on writing production Go systems that are easy to debug and troubleshoot. Jack Lindamood from SignalFx presents patterns that facilitate this process.
Jack addresses tools built into Go you can take advantage of, build process techniques they've learned over time, and open source tools and libraries you can use that help troubleshoot your production code when things go wrong.

Azul Virtual Machine Engineer Douglas Hawkins describes how decisions made by the JVM affect how your code is compiled and run. Learn how this affects application performance and what steps you can take to optimize how the JVM acts on your code.
Try to imagine the amount of time and effort it would take you to write a bug-free script or application that will accept a URL, port scan it, and for each HTTP service that it finds, it will create a new thread and perform a black box penetration testing while impersonating a Blackberry 9900 smartphone. While you’re thinking, Here’s how you would have done it in Hackersh:
“http://localhost” \
-> url \
-> nmap \
-> browse(ua=”Mozilla/5.0 (BlackBerry; U; BlackBerry 9900; en) AppleWebKit/534.11+ (KHTML, like Gecko) Version/7.1.0.346 Mobile Safari/534.11+”) \
-> w3af
Meet Hackersh (“Hacker Shell”) – A new, free and open source cross-platform shell (command interpreter) with built-in security commands and Pythonect-like syntax.
Aside from being interactive, Hackersh is also scriptable with Pythonect. Pythonect is a new, free, and open source general-purpose dataflow programming language based on Python, written in Python. Hackersh is inspired by Unix pipeline, but takes it a step forward by including built-in features like remote invocation and threads. This 120 minute lab session will introduce Hackersh, the automation gap it fills, and its features. Lots of demonstrations and scripts are included to showcase concepts and ideas.

Apache Beam (formerly Google Cloud Dataflow SDK) is an unified model and set of language-specific SDKs for defining and executing data processing workflows. You design pipelines, simplifying the mechanics of large-scale batch and streaming data processing and can run on a number of runtimes like Apache Flink, Apache Spark, and Google Cloud Dataflow (a cloud service).
This presentation introduces the Beam programming model, and how you can use it to design your pipelines, transporting PCollection and applying some PTransforms. You will see how the same code will be "translated" to a target runtimes thanks to a specific runner. You will also have an overview of the current roadmap, with the new interesting features.
ECMAScript 6 (ES6) is getting closer and closer with more support available in both node 0.12.0 and io.js. ES6 promises to fundamentally change the way we develop applications on node.js by allowing for the use of generators for iterators and a standard promises library for orchestrating our asynchronous calls. In this talk we will explore the implications of ES6 for the node driver and applications written on top of the driver.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.

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?
Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.

1. Running Untrusted Code in Spring
with WebAssembly
Dave Syer (2022)
@david_syer dsyer@vmware.com
2. What is WebAssembly?
● Host = application code (e.g. browser)
● Guest = WASM, compiled from C, C#, AssemblyScript, Rust, etc.
● Spec: https://github.com/WebAssembly/spec
● Originally targeted at browsers, so JavaScript is most common host
● Other hosts include Rust, Go, Python, C#, Java
● Sandbox - flexible with secure defaults
Host
Guest
3. Show me Some Code
(module
(func (export "add") (param i32) (param i32)
(result i32)
local.get 0
local.get 1
i32.add
)
)
Example playground:
https://developer.mozilla.org/en-US/docs/WebAssembly/Reference/Numeric/Addition
4. Linear Memory
(module
(memory (export "memory") 1)
(func (export "get") (param i32)
(result i32)
(i32.load (local.get 0))
)
)
1 page of memory is exported and accessed externally via the “get” function
5. Imports and Exports
(module
(import "env" "get" (func $get (result i32)))
(func (export "echo") (result i32)
(call $get)
)
)
The result of the “get” function is echoed back to the caller of “echo”
6. Options:
● Emscripten: https://github.com/emscripten-core/emscripten
● Wasi SDK: https://github.com/WebAssembly/wasi-sdk
● Binaryen: https://github.com/WebAssembly/binaryen
● Llvm/Clang: https://github.com/llvm/llvm-project
Echo Guest: C
int get();
int echo() {
return get();
}
Try it out at https://wasdk.github.io/WasmFiddle/
14. Exchanging Data Between Host and Guest
● Choose a binary format, e.g. Protobuf, Avro, MessagePack, JSON string
● Convert input and copy into shared memory
● Call WASM function with [ptr, len] tuple
● Output is another [ptr, len] tuple
● Copy output from shared memory and convert
ptr (input)
len
ptr (output)
len
15. Application Binary Interface (ABI)
Contract for exchanging data:
● Allocate and free memory (host and guest have to agree on location)
● Binary encoding format, e.g. Protobuf definitions
● Signature for exports - structure of input and output pointers
● (Optional as necessary) signature of imports
Draft spec for standardization: https://github.com/WebAssembly/component-model
16. Message Exchange Host: JavaScript
var encoded = encode(msg);
const bytes = malloc(encoded.length);
new Uint8Array(memory.buffer).set(encoded, bytes);
const output = malloc(8);
const input = malloc(8);
new Uint32Array(memory.buffer, input, 2).set([bytes, encoded.length]);
wasm.instance.exports.call(output, input);
var buffer = new Uint32Array(memory.buffer, output, 2).slice();
var result = message.SpringMessage.deserializeBinary(new Uint8Array(memory.buffer, buffer[0],
buffer[1]));
free(output);
free(input);
return decode(result);
input object
memory management (imported from wasm)
17. Message Exchange Host: Java
var buffer = memory.buffer(store);
try (var input = new Wrapper(buffer, message);
var output = new Wrapper(buffer)) {
linker.get(store, "", "call").get().func().call(store, Val.fromI32(output.ptr()),
Val.fromI32(input.ptr()));
return output.get(SpringMessage.class);
}
input object
memory management
18. Spring Host Ideas
● Some glue code for boilerplate WASM host stuff
● Spring Cloud Gateway - predicates and filters
● Spring Cloud Function - generic data transformation
● Kubernetes operator - webhook or controller, e.g. Cartographer
Demos:
● https://github.com/dsyer/spring-wasm-demo (client: C; host: Spring)
● https://github.com/dsyer/async-wasm (client: C, AS, Rust; host: javascript)
