Thank you for your help


i installed BLCR 0.8.5 on my ubuntu 12.10  to be used for MPICH -3.0.3
this version of blcr should support to kernels through 3.7.1

when i run the command :
basma@basma-Satellite-A500:~$ mpiexec --info

results:

so i thought that every thing is ok but when i try to rum mpiexec it failed:
