configure container to use the MPI library installed on HPC.

[lorincmeszaros]

@avgils @backeb I confirmed internally that Deltares has a container that can use the MPI library at the Host, we have this for the 2022.02 release. Yvonne will send the container with instructions to Anna.

@nikosT @kkoumantaros : Do you have IntelMPI installed at the cluster and (if yes) which version it is? When we try to set this up, will you have a sysadmin help us out? Who should be the contact person?

[nikosT]

@lorincmeszaros Yes, we do. We have various versions of it. Is intelmpi/2018 suitable for you? Yes, you can always send an e-mail at support at hpc.grnet.gr and an admin will be answering back to you.

Thanks @nikosT ! We can try with the older one but it was only tested with IntelMPI 2021.2 and 2021.4.

@avgils

[nikosT]

@lorincmeszaros, you can also load the oneAPI module, which includes the intelMPI 2021.4.

[lorincmeszaros]

this is what we see (2021.3):

[nikosT]

@lorincmeszaros Could you try:

module purge
module load oneAPI/2021.3
module avail # see under oneAPI section available modules
module load compiler
module load mpi # this is the intelmpi 
mpiicc --version # intelmpi uses double "i" in commands

which will eventually load intelmpi 2021.3.

You could also try module load oneAPI/2022.1, and then follow the same steps, which will load intelmpi 2021.5.

PS: I was confused with the number versions, where no .4 is installed, however probably both .3 and .5 will suit you.

[avgils]

@nikosT Thanks for this example I see intelmpi 2021.3.0 :)

@nikosT

@avgils submitted jobs to test the mpi library but stuck in the queue. Do you have recommendation how to jump the queue? Using test queue for short runs or similar?

[nikosT]

@lorincmeszaros, generally, you can not jump in the queue, in terms of fairness. However, you could use partition el7thin with 2 allocated nodes.
