Hi,
PBS version : 2021.1.3
OpenMPI : 5.0.3
I’d like to do a partial oversubscription with MPMD, like this
1. Request 40 trunks in total
2. First group of 32 trunks with 128 cores per trunk, 1 MPI rank per core, 1
OMP threads per MPI rank
3. Second group of 8 trunks with 128 cores per tru
Hi,
I'm trying to build an OpenMPI 5.0.3 environment on the Cray EX HPC with
Slingshot 10 support.
General speaking, there were error messages while building OpenMPI, and make
check also didn't report any failure.
While tested OpenMPI Env. with a simple 'hello world' MPI Fortran codes, it
if run on single node.How to
figure out the possible reasons?
Appreciating your kindly input

Dear Sir/Madam,
1. If specified '--mca btl tcp,self', which interface application will run
on, use GigE adaper OR use the OpenFabrics interface in IP over IB mode (just
like a high performance GigE adapter) ?
2. If '--mca btl tcp,self' forced application to use GigE adapter, how to

Hi,
The man page said all other command line options will be ignored if --appfile
used.
So just wondering
1. how to specify "--mca btl ^sm " option while launching MPMD applications
with --appfile?
2. how to know the option "--mca btl ^sm " worked?
Appreciating your kindly help
