Re: [Beowulf] more automatic building

Many thanks for all answers ! It looks for me now that OpenHPC choice may will be best for me. 1 of my 2 existing clusters is based on RH, 2nd - on OpenSuSE. Basing of OpenHPC on repositories is plus for me. Plus support of mvapich2/OpenMPI/intelMPI (I don't know about basical MPICH).  Etc.

[Beowulf] more automatic building

OSCAR or even ROCKS. But it looks that ROCKS don't support modern interconnects, and there may be problems w/OSCAR versions for support of systemd-based distributives like CentOS 7. For next year - is it reasonable to wait new OSCAR version or something else ? Mikhail Kuzminsky, Zelinsky

Re: [Beowulf] Register article on Epyc

te2006 may be good for Epyc 7601 because of 32 cores per CPU instead of 22 cores for Broadwell Xeon E5-2699A v4. Xeon Phy KNL cores also gives 32 DP FLOPS per cycle. By my opinion, it's necessary to wait results of normal HPC tests. Mikhail Kuz

Is it possible to use diffenent slurm versions on different worker nodes of cluster (w/other slurmctld and slurmdbd versions on head node) ? If this is possible in principle (to use different slurmd versions on different worker nodes), what are the most important restrictions for this? Mikhail

Re: [Beowulf] Fortran is Awesome

I believe that the rationality of FORTRAN using is and now very much dependent on the application. In quantum chemistry, where I previously programmed, as also in computational chemistry in general, Fortran remains the main language. Yes, C is dangerous. You can break your code in ever so many

[Beowulf] GPUs Nvidia C2050 w/OpenMP 4.5 in cluster

Heterogeneous nodes in my small CentOS 7 cluster have x86-64 CPUs along with the old Nvidia GPU C2050 (Fermi). New Fortran program uses MPI + OpenMP software. Does the modern gfortran or Intel ifort compilers give support of work through OpenMP 4.5 with these GPUs? Mikhail Kuzminsky

[Beowulf] likwid vs stream (after HPCG discussion)

that for the HPC user, stream gives a more important estimate - the application is translated by the compiler (they do not write in assembler - except for modules from mathematical libraries), and stream will give a real estimate of what will be received in the application. Mikhail Kuzminsky
