I’m so glad to announce that the computational model I developed during my PhD is now a stand-alone software and has recently passed the strict review process of my favorite journal, Journal of #OpenSource Software 🤩

doi.org/10.21105/joss.…
Let me explain it a bit 👇
(2/9)
BioDeg is an #opensource cross-platform software written in #FreeFEM, C++, and Python for modeling the degradation of metallic #biomaterials and simulating the #biodegradation behavior of medical devices and #implants in #corrosion experiments.
(3/9)
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.

Wanna try @nextflowio DSL2?

Our #climbBioinfoskills tutorial is available online! 🧵 Image
#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!

My slides are available on Github: github.com/Bioinfo-skills…
And the repository itself shows a simple example of a "de novo" assembly pipeline for bacterial genomes

#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.
ABC Tiiriön 50kW 🇪🇸 Efatec #Recharge laturi on erinomaisella paikalla, harmillisesti vain yksinäinen. Oli vapaana mutta 10min latauksen lopulla tuli toinen auto jonottamaan. Latausnopeus odotettu 40kW.

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

Ok I feel a rant coming on…
Imagine showing up to the Top500 podium and celebrating #1 when you know Serena Williams didn’t show up to play because she didn’t think your tourney was worth her effort. That’s how foolish it’ll look this Top500 at SC21.
Today is the death of the Top500. I’m calling time of death the moment @NicoleHemsoth hit submit on this article. It’s over. I can’t imagine anyone else submitting future numbers when we know there are better out there.
The US in a way set itself up for this. It spent years dominating Top 10 and irking friends. I don’t know anyone that loves competing in this metric but they got invited to play in a court built especially for Michael Jordan to dunk on others. Then Yao Ming didn’t show up to play

Are you interested in reaction-diffusion systems? Also want to know more about coupling them with moving interface problems? Especially if it’s related to #HighPerformanceComputing and elaborated on it? Then, don't miss our recent publication😉👇
doi.org/10.1177/109434…
(2/8)
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.
(3/8)
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

Interesting read: @jonmasters uses the return of @PGelsinger to @intel as an excuse to talk about how the semiconductor world has changed with a small number of #cloud vendors calling the shots

medium.com/@jon.masters/p…

#HPC #AI
@jonmasters 2/
The future has only 6 or 7 customers driving demand

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

#Cloud
@jonmasters 3/

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)

1/ How should we talk about DP FLOPS for A100? A thread. #HPC #AI #Nvidia
2/ Nvidia announced A100 this morning and you can read about it from any number of outlets, e.g. nextplatform.com/2020/05/14/nvi…
3/ Nvidia, as usual, have themselves published a great set of detailed blogs about the architecture and specs, really diving into the approaches they've taken and how they might impact workloads.

#MDSI2019 Day2 Session 2: "Standardization of file format I/O" by @jppiquem.

Straight into problems -- input files are a tougher cookie to crack than output 🍪
Actually, Day 2 Session 3 #hasphdcantcount
#Input: Many problems -- many possible solutions! How to find the right one? #goldilocks

#Output: probably easier to handle and we can learn from other fields, like climate research.

Holy crap. Gemalto's IDPrime.NET cards - the ones they tout being Windows native compatible - are suscept. to factorization.
1) Researchers have found a process to duplicate a PRIVATE key just from the PUBLIC key. This is big.

And cheap, for a 1024bit key.
2) Gemalto are a large mfgr of smartcards. Their IDPrime.Net cards are popular because they work with Windows w/o extra software
