Ah yes, OpenFoam, forgot about that one.  Spack has OpenFoam 8 installed.  If I remember correctly (perhaps I’m not) OpenFoam is really “one installation pergroup (or person)” given compile time and linking etc. issues.

 

Anyone compile it recently?  Ahh looks like they have a docker image already.

 

Tim.

From my experience, OpenFOAM is a good deal of use. My officemate at Penn State developed for it and used it for his wind turbine work. I'm not sure how widespread the use is, but I had some requests for Moose as well, although that was mainly from one group. 

 

I've installed (or attempted to install) the software; however, I've never managed to learn much in the way of CFD due to my background. 

 

Best,

So, my memory is fading from my time at MU in terms of software and domains – what are the main CFD codes being used on campus today?  I’m only familiar with COMSOL – are there any open ones in common use?   Are there any good REAL benchmarks that don’t look like linpack? Anyone working with a researcher that has a need to benchmark (perhaps looking to XSEDE)? (my optioning is that REAL benchmarking needs a real researcher :grin:).

Where I'm at is: I know enough about container orchestration to describe it at a high level. While this works I can't really claim I'm "happy" with my degree of comprehension; and in addition I have a sense of where the rubber meets the road for cloud research computing advocacy. And by this I mean outside the curriculum scope that CJ describes (also super important). So: Can the cloud hold a candle to on prem distributed hpc. My feeling is that the poster child implementation is computational fluid dynamics. Supposing I were to dive into k8: I'd first spend some time looking into Singularity containerization; and the main goal would be an HPC implementation of a CFD sort of computation with benchmarking to get to unequivocal remarks comparing to an on prem cluster / slurm / MPI / infiniband run at the same problem. I'm sure this has been done a number of (zillion?) times and I'd be super pleased to get a pointer to a good example... in my case it's always a matter of finding uninterrupted blocks of time. Anyways that's my take on this important topic.

Tim,

I'm also interested in this event. I think the learning format works! A month's pace is fine to me, since I am very new to Kubernetes. Currently, Kunernetes isn't on my radar, but I know that it will be of some use to me in the future.

 

Thanks,

Eric

Tim,

   This event sound very interesting and glad that you forwarded it on to this list.  We are using Kubernetes on AWS to manage JupyterHub instances for class courses here at OSU.  Any extra training on Kubernetes is welcomed, especially when it’s free 😉.

Question for the community,

 

Are events like these of use? 

https://www.nginx.com/c/microservices-march-2022-kubernetes-networking/

 

(there is a short explainer video about what it is on the page – basically a 16 hour kubernetes tutorial)

 

Does the learning format work or is it when you need learn something, you need it yesterday and don’t have time to consume them at a month’s pace?

 

Where is Kubernetes on your radar?

 

Is this reference of value to the community?

 

Regards,

 

 

Tim.
