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.
Large Language Models and the End of ProgrammingMatt Welsh
Talk by Matt Welsh at Craft Conference 2024 on the impact that Large Language Models will have on the future of software development. In this talk, I discuss the ways in which LLMs will impact the software industry, from replacing human software developers with AI, to replacing conventional software with models that perform reasoning, computation, and problem-solving.
Code reviews are vital for ensuring good code quality. They serve as one of our last lines of defense against bugs and subpar code reaching production.
Yet, they often turn into annoying tasks riddled with frustration, hostility, unclear feedback and lack of standards. How can we improve this crucial process?
In this session we will cover:
- The Art of Effective Code Reviews
- Streamlining the Review Process
- Elevating Reviews with Automated Tools
By the end of this presentation, you'll have the knowledge on how to organize and improve your code review proces

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.
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 ?

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.

or "There is error in your sound system, music can't be heard."
9. Christmas 2001
Maldal virus spread via email using a seasonal electronic
greeting card called Christmas.exe.
Picture: Santa Claus on skis accompanied by a prancing
reindeer
Message: "From the heart,
Happy new year!".
11. IBM Christmas Card: Facts
When: 09th December 1987
Name: Christmas Tree Exec
Place of Origin: Germany
Significance: Worms were first noticed as a potential
computer security threat
Effect: It brought down both the world-wide IBM
network and BITNET
Source Language: REXX
12. Behavior
E-mail Christmas card
Subject line "Let this exec run and enjoy yourself!”.
Included executable code.
Claimed to draw a Christmas tree on the display.
The user had to execute the program by typing christma
or christmas.
14. A comment inside the source code:
browsing this file is no fun at all just type
CHRISTMAS from cms
Sent a copy to everyone on the user's address lists.
15. Working
Read the files:
NAMES: Collection of information about other users with
whom you communicate
NETLOG: File transfer log
Mailed itself to every email address
Approximate number exceeded 1,000
People trusted it, because it was coming from a regular
correspondent
16. The Name: CHRISTMA EXEC
IBM VM systems originally required file names to be formatted
as
8 characters + space + 8 characters
IBM required REXX script files to have a file type of "EXEC”
17. Source of the Christmas card
A student at the University of Clausthal in West
Germany
REXX scripting language: a shell script-like language for
IBM’s VM/CMS system
Found by December 21
Barred from using his/her system.
“The damage was unintentional and that the program
was written to send Christmas greetings to my friends.”
18. Damage Done
Worm itself wasn’t malicious
Exponential growth patterns
Clogged servers, communication paths, spool directories
Unintentional denial of service attack
19. Damage Done
EARNet:
The European Research and Education Networking
Association (TERENA)
BITNET:
BITNET was an university computer network founded in
1981s at the City University of New York (CUNY) and Yale
University
Destroyed by December 14th
20. Damage Done
IBM's VNet electronic mail network
International computer networking system deployed in the
mid-1970s.
Developed inside IBM
Provided the main email and file-transfer backbone for the
company
December 15th
Paralyzed on 17th December
Brought to a standstill two days later, only getting rid of the
worm by shutting down the network.
In 1990, Christmas Tree resurfaced after being posted to
Usenet. IBM was forced to shut down its 350,000-terminal
network
21. Countermeasures Taken
Programmer at Cornell University had written a simple
program
Examined the network queues every five minutes and delete any
files called Christma Exec;
Purged about 300 copies in four and a half hours.
Other operators did the same, writing and passing around ad-
hoc program to eliminate copies of the worm.
22. Countermeasures Taken
Such simple tools could only sample the queues every few
seconds and purge what they found
Worm could still sneak through to a limited degree.
In Israel, one programmer wrote a program “anti-Christma
Christma,”
Examined users’ netlog to determine whether they had been
victimized
If yes, the new Christma would retrieve any copies of the
original that had not yet been read by the addressee and then
send itself onward to the same set of targets used by the
original Christma.
23. Debate: Trojan or Worm
Trojan:
Appear to be useful, but will do damage once installed
Required the user to download and run the attachment to
make it replicate
Worm:
Virus Encyclopedia refers to it as a worm.
Worms move from one computer to another regardless of any
human action
