Choosing the mpich version

Recent versions of SCore also support multiple versions of mpich. At the time of writing these are mpich-1.2.0 and mpich-1.2.4. To compile using a particular version of mpich add the -mpi option to the compiler commmand - e.g

[nrcb@ehtpx-cluster mpi]$ mpif77 -mpi mpich-1.2.4 -compiler intel7 -O3 -w -o jacobi_mpi jacobi_mpi.f aloc.o
   program JACOBI
   external subroutine OUTPUT
   external function UEXACT
   external function FEXT
   external subroutine INITIALISE
   external subroutine ERROR
   external subroutine ITERATE

The default version of mpich if you don't use the -mpi flag depends on the version of SCore. For SCore version 5.0.1 the default is mpich-1.2.0 and for SCore version 5.2 or later it is mpich-1.2.4.
