Openmpi support

[adarsh]

Does this mean “my openmpi didn’t support PBS”? But it seemed that I can use “mpirun” in pbs job scripts.

PBS Supports openmpi, but the openmpi should be compiled with PBS TM option.

@liuxiaopiao

Do I need to install openmpi by compiling the code with " --with-tm option"?

Thats correct, for this to work you need to compile openmpi with PBS TM , please follow the below

Compile OpenMPI with PBSpro 14.1.10

Adding a pbs_config script is one way of making openmpi’s configure to succeed, but here also a simple manual way to do it: export LD_LIBRARY_PATH=/opt/pbs/lib:$LD_LIBRARY_PATH export LDFLAGS="-L/opt/pbs/lib -lpbs -lpthread -lcrypto" ./configure --with-tm=/opt/pbs This should simply configure openmpi with PBS tm support. I tried with 2.0.2 as well.
