Description
Hello.
I'm trying to run a job directly with mpiexec on Jasmin and I think I'm missing some steps. Can you clarify them for me, please?
I get two types of error: "Cannot open shared object file" and "All nodes which are allocated for this job are already filled."
The test is in /home/users/lucy/ESDM-test-script and the file readme has the instructions that I'm using to run it and the final outcome with the error messages.
Kind regards.
Luciana.

I don't think the unable to open mca_ess_lsf: libbat.so: is a problem - it's referring to lsf.
It's unusual to run mpi jobs anywhere other than on Lotus, so I'm not surprised there is resource issued.
You could try running with 1 ensemble member on 2 processors (say) and xios on 2 processors and use the "test" queue (see https://help.jasmin.ac.uk/article/4881-lotus-queues).
{I'm not sure if the test queue supports mpi jobs - I am led to believe it does}
