[mvapich-discuss] Finding the right version of MVAPICH2

[Panda, Dhabaleswar]

Hi,

Thanks for your note.

For pure CPU-based applications, please use MVAPICH2-X.

For GPU-based applications, please use MVAPICH2-GDR.

Both these versions support containers technology.

We are working on a merged  version of these two and it will be available in a few months. After that, you can use this merged version everywhere.

Please note that AWS has a separate network adapter (EFA). Support for this EFA adapter is available under MVAPICH2-X.

Let us know if you encounter any issues.

Thanks,

DK

Subject: [mvapich-discuss] Finding the right version of MVAPICH2

Hi all,

My research group at UNICAMP (led by Prof. Guido Araujo) developed a distributed runtime which use MPI as the underlying communication infrastructure. I would like to experiment it with MVAPICH2 but I am having some difficulties to decide what would be the best version of MVAPICH2 according to our specific situation:

  *
All applications which make use of our runtime are deployed using containers technology (docker or singularity) but usually with only a single container by node;
  *
Some of those applications use GPUs to perform the computation and some only use CPUs;
  *
Those applications might be deployed on cloud service provider (either AWS or Azure) or on more traditional HPC clusters (but still using containers);

Should we provide a single container using MVAPICH2-Virt or should we provide multiple possible configurations to our users?

Thanks for the help,
Hervé
