The app.DeepSquare.run Customer Portal provides easy access to our infrastructure and an array of pre-built applications, including #Text2Image, #Blender, @unity Render Streaming, and #AI Upscaling.
The Developer App within the portal is a game-changer for those looking to create and run custom jobs in an #HPC environment.
It offers unmatched flexibility and ease of use, enabling users to develop and deploy their applications on the @DeepSQUAREio infrastructure.

And @PGelsinger takes the stage and immediately confirms that this is the launch of the fourth-generation #Xeon processor known as #SapphireRapids. He’s also emphasizing the #XeonMax brand!
@PGelsinger immediately turns it over to a video featuring @MichaelDell of @DellTech, then the CEO of @InspurSystems, then @AntonioNeri_HPE of @HPE, then @Lenovo
Something a little different today:
A blog post on the curious case of Alder Lake, the quest for reduced precision on x86, preparing HPC FOSS libraries and documentations, and how a certain vendor made it explicitly harder to support their own hardware.

This is an abridged recounting of months of works which is still ongoing to this day.
Writing this up stemmed from a tangent with @owainkenway about needing special microcode revisions within custom kernels, and instead of just an email, turned it into a post of sorts.

Some of the content is a little harsh towards certain entities. I want to be clear to those at said entities that I truly do value the amazing work you do and that I still believe in you longer term.
Heck I'm still open to working with you on fixing some of these problems!

I have benchmarked the new @AMDInstinct MI250 #GPU at @fzj_jsc, and it is disappointing but also impressive. Let me explain.

The #MI250 is misleadingly marketed as "one chiplet GPU" with 13312C, 90TFLOPs & 128GB @ 3.2TB/s.
But it is not. The 2 GCDs are 2 separate GPUs with 64GB each, like a K80 dual-GPU but in a socket. One #GPU can't directly access the other's memory.

To use both GCDs, the software needs to be multi-GPU capable. For many algorithms this is very difficult and for some it is entirely infeasible. The desire for large unified memory is huge.
The #MI250 promises exactly that with "128GB", but delivers only half.

The necessity and the details of the computational model of #biodegradable materials, which does the main simulation behind the scene, are already discussed in this Twitter thread, so make sure to have a look at it if you like to know more 🤓

We just published the “Ten Simple Rules for Large-scale Data Processing” with @GreeneScientist @seandavis12 @infoecho @localee_compact @datawheeler @jaclyn_taroni based on our experience. journals.plos.org/ploscompbiol/a…

#Bioinformatics #BigData #CloudComputing
Thank you to all the authors for sharing their thoughts and contributing to writing/editing. I learned several tips in our discussion.
These rules are focusing on the technical planning process and should be considered as a companion to other recommendations that are more focusing on policy, ethical, or compliance aspects.
#Nextflow is a fantastic language and workflow runtime, which allow us to write clean logic and to separate it to the configuration. The same workflow can transparently run locally, on your #HPC or in the #cloud!

#Sähköauto Nissan #Leaf 40kWh matkaa 338km Pohjanmaalle. Pakkasta aamulla Helsingissä -16°C. Matkalla 3 lyhyehköä pikalatausta yht 1h sekä lounaan ajan 3kW AC latausta. Kangasalan kautta ajaessa kokeillaan mahtuuko siskon 2 turvaistuinta ja lastenrattaat tähän tilaihmeeseen.
Auton mittari kertoo -15°C. Kyllä on mukava lähteä lämpimällä autolla ja ikkunat sulana liikkeelle. Akku myös tukevasti pakkasella, mutta varmasti lämpenee ennen ensimmäistä #Chademo pikalatausta, #goldgate nimellä kulkeva kylmän akun hidas lataus ei vaivaa #Leaf’ia.

Incredibly happy that our @RoboStack paper has been accepted to the @ieeeras Robotics & Automation Magazine 🥳. @RoboStack brings together #ROS @rosorg with @condaforge and @ProjectJupyter. Preprint: arxiv.org/abs/2104.12910. Find out some key benefits in this 🧵: 1/n
You can now easily use ROS (both ROS1 #Noetic and ROS2 #Galactic) on a wide range of platforms: @linuxfoundation (not just a specific Ubuntu, any Linux!), @Apple #MacOS and @Microsoft @Windows - even on ARM processors including the new M1 (work still in progress, though). 2/n
Thanks to the tight coupling to @condaforge, this enables you to (very easily) install ROS side-by-side with thousands of scientific libraries, including recent #computervision and #machinelearning ones (think @TensorFlow, @opencvlibrary, @PyTorch and more). 3/n

Reaction-diffusion systems coupled with moving interface problems (in which the boundary of the domain is part of the solution 🙂) have great importance in various real-world scenarios in chemistry and chemical engineering as well as environmental and life sciences.

As an example of such systems, we developed an #InSilico model of the #biomaterials degradation phenomena, in which the loss of material due to #corrosion (#biodegradation) leads to movement of the material-medium interface.

A lot of folks have asked about what we used to build out the infrastructure for the hackathon. 1/22
I'm going to lean on @ollyperksHPC and @CQnib and others who worked really closely to look after both the orchestration of the clusters themselves as well as the "insides" of the clusters (packages, compilers, libraries etc). 2/22
Firstly, we extensively used @awscloud #ParallelCluster, which takes spec files that more or less say - "gimme a cluster with, lemme see ... I think I want Slurm today, and up to 16 compute nodes made from Graviton2, I also want EFA for doing fast MPI stuff, oh, and a… 3/22
Drum-roll, please: @OllyPerksHPC and I just announced the winners of the @awscloud/@arm Summer Cloud HPC #ahugHackathon hosted by @ArmHPCUserGroup. 1/17
The judges were really impressed by the incredible effort from across the community that saw the participants get 31 codes working on Graviton2-based #HPC clusters that previously only built and ran on other, mostly x86-based, lifeforms. 2/17
This lifts the water level for the whole Arm-HPC community. 3/17

They are both extremely sophisticated AND more than capable of taking matters into their own hands, in-house
They’re larger than any of the component suppliers from which they source their compute needs today

The “lock in” of the next decade won’t be literally “your software only runs on my #Cloud but more that it “runs better on my cloud”
Because I coupled a “right sized” design with the right accelerators and made it “just work”!

@DukePallCare SUCCESS! Journal Club Time Machine: Speed Dating with the Classics. Format - everyone in attendance (MS2-Attending) teaches a classic article for 4 minutes, it is put in context by someone old for 1-2 min, and we move on. Here's the list! A #HPC thread:
No 1 - SUPPORT Trial: pubmed.ncbi.nlm.nih.gov/7474243/. 5 AMCs. Docs don't know pt's CPR preference, many DNRs within 2d of death, lots of ICU time and pain. RN led intervention gives docs data. Centers around communication. NO CHANGE IN KEY METRICS.
No 2 - Prognostication: pubmed.ncbi.nlm.nih.gov/10678857/. Docs of pts referred to #hospice asked for assessment of prognosis. Only 20% accurate (+/- 33%) with most over-optimistic. Average miss factor of 5.3! Longer pt/doc relationship = worse prognostication accuracy (#LoveThemTooMuch)
