Thanks! This sounds like a simple solution.
I tried it and got some errors:

mex: -pthread not a valid option.
Usage:

or (to build an Ada S-function):

Use the -help option for more information, or consult the MATLAB
External Interfaces Guide.

If I setenv LAMCC mex
I get:
losangeles[24]% mpicc
mex: -pthread not a valid option.

But if I setenv LAMCC gcc
I get:
losangeles[27]% mpicc

Yes, mex is a script provided by Matlab. But I am not able to
modify it yet. Any further suggestions on how to solve it problem?
Thanks a lot,
