1 In the 'bin' directory containing mpif90, the following command shows ifort is used.

$./mpif90 -v

mpifort for MPICH version 3.1.2

ifort version 14.0.3

2 ifort -mcmodel=medium won't work. 

Since large array could not work with mpich in my computer,

I downloaded openmpi and now it is working fine. The parallel code being modified from the serial

version

is now working.

Thank you for your attention
