compiler problem

Post by lagoun brahim » Tue Mar 02, 2010 4:14 am

HI every one
I installed intel fortran compiler but after configuring MPICH2 and abinit-5.8.4 I realize that it is configured with the system compiler (gcc-4.2)
I have two questions:
1-what is the feast of compiling both with gcc makes them less reliable (in therm speed)
2-how can I force them to configure itself with the ifc
thanks

1. I don't understand your question.

2. Pass FC=ifort as an argument to configure.
