[SCore-users-jp] [SCore-users] Best way to increase the stacksize limit on MPI jobs?

[Nick Birkett]

Does anyone know if it is possible for an mpi processes to increase the stack 
size limits ? 


I had this query from one of our users:

ulimit sets the stack size for a shell, so is not probably not what is
wanted. Probably this is a general programming problem not related to
Score mpi.

Thanks,

Nick
