Arc: An IR for Batch and Stream ProgrammingLars Kroll
There is currently a large number of data programming models and their respective frontends such as relational tables, graphs, tensors, and streams. This has lead to a plethora of runtimes that typically focus on the efficient execution of just a single frontend. This fragmentation manifests today into highly complex pipelines that bundle multiple runtimes to support the necessary models. Hence, joint optimisation and execution of such pipelines across these frontend-bound runtimes is infeasible. We propose Arc as the first unified Intermediate Representation (IR) for data analytics that incorporates stream semantics based on a modern specification of streams, windows and stream aggregation, to combine batch and stream computation models. Arc extends Weld, an IR for batch computation, and adds stream interoperability as a natural extension to describe static computational graphs suitable for stream processing.

Adaptive Compilation by Jecel Mattos de Assumpção JrFAST
Traditional language implementations are interpreters and compilers, though it is possible to mix them: compiling source text to some bytecode which is then interpreted, for example. The performance of a hybrid system can be much greater by also compiling the bytecode to native machine language dynamically, which is known as JIT (Just In Time) compilation. The problem with this is that the compiler now has to do its job really fast because it is getting in the way of executing the actual application code.
Most of the time is spent executing a tiny fraction of the code, known as the hot spots. An adaptive compiler can quickly generate usable code for the common case and then dedicate a lot more time doing a better job on the hot spots for a better overall performance. Such a system has unique advantages and complexities.

Spectral Analysis of Sample Rate ConverterCSCJournals
The aim of digital sample rate conversion is to bring a digital audio signal from one sample frequency to another. The distortion of the audio signal introduced by the sample rate converter should be as low as possible. The generation of the output samples from the input samples may be performed by the application of various methods. In this paper, a new technique of digital sample-rate converter is proposed. We perform the spectral analysis of proposed digital sample rate converter.
Accurate Synchronization of EtherCAT Systems Using Distributed ClocksDesign World
Synchronization and determinism are important considerations when selecting an industrial control system and the associated fieldbus. Additionally, it’s important for field devices to have network-wide interrupts for activating outputs, capturing input data, oversampling or latching events. These are all significant facets in the overall network synchronization scheme.
This webinar on Tuesday, Oct. 23 at 2 PM EST will explain how the Distributed Clock mechanism in EtherCAT works to meet all of these functions using properties inherent to the protocol. This can be done using a standard Ethernet network adaptor, all without the overhead of IEEE 1588.
Attend this webinar to learn:
How Distributed Clocks (DCs) in EtherCAT facilitate measurement of propagation delay throughout the system and synchronize network devices to a single time value
What EtherCAT slave devices can do to facilitate temporal behavior for outputs and inputs as well as implementing data oversampling
More about some of the concepts that enable EtherCAT to have a high scan rate as well as high levels of synchronization

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.
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.
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.

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.
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.

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. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources. In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.
Paketo Buildpacks : la meilleure façon de construire des images OCI? DevopsDa...Anthony Dahanne
Les Buildpacks existent depuis plus de 10 ans ! D’abord, ils étaient utilisés pour détecter et construire une application avant de la déployer sur certains PaaS. Ensuite, nous avons pu créer des images Docker (OCI) avec leur dernière génération, les Cloud Native Buildpacks (CNCF en incubation). Sont-ils une bonne alternative au Dockerfile ? Que sont les buildpacks Paketo ? Quelles communautés les soutiennent et comment ?

6. DOMAIN MODELLING
• Records, unions and units of measure let us model hardware
capabilities and experiment parameters clearly and concisely
• We get structural equality and serialisation for free
type Frequency = FrequencyInHz of float<Hz>
type Amplitude = PowerInDbm of float<dBm>
type StepSpacing = LinearSpacing | LogarithmicSpacing
type Range<'T> = { Start : ’T ; Stop : 'T }
type FrequencySweep =
| FrequencySweep of range : Range<Frequency>
| FixedFrequency of frequency : Frequency
type AmplitudeSweep =
| AmplitudeSweep of range : Range<Amplitude>
| FixedAmplitude of amplitude : Amplitude
type StepSweep =
{ Frequency : FrequencySweep
Amplitude : AmplitudeSweep
NumberOfPoints : int
Spacing : StepSpacing }
7. INSTRUMENT CONTROL
• Communication to hardware is inherently async
• async workflows are great metaphor for
experiments
• Use asyncChoice (available in ExtCore) and
railway-oriented programming to handle errors
8. DATA ACQUISITION
type StreamingAcquisition =
{ Parameters : StreamingParameters
Buffers : AcquisitionBuffers
StopCapability : CancellationCapability<StreamStopOptions>
StatusChanged : Event<StreamStatus>
SampleBlockObserved : Event<SampleBlock> }
let run scope acquisition = asyncChoice {
use acquisitionHandle =
PicoScope.Acquisition.allocateHandle digitiser acquisition.Buffers
do! prepare scope acquisition
do! startStreaming scope acquisition
do! pollUntilStopped scope acquisition }
• Acquisition emits samples via Event<‘T>, so we can feed this straight
into FSharp.Charting
• Use Rx transformations to implement signal processing
9. WHAT DO OTHERS USE?
C / C++
• Low level, manual memory and thread management
Python
• Global Interpreter Lock can cause problems
• Pay the price for dynamic typing in large projects
C# (… in industry?)
10. LabVIEW
• Looks and feels like it belongs in the 90s
• … but has a vast library of instrument drivers
11. SUMMARY
• F#’s type system allows us to model our problem
domain clearly and concisely
• Many of the tools we need are already available
(async, Rx, FSharp.Charting)
• F# is very well suited to the task but lacks
instrument libraries and user base
