It looks like you might have missed installing the kernel module for BLCR. What is the output of `lsmod`?
Alternatively, if you installed BLCR by using apt-get in Ubuntu, you should be able to use dkms to manage your kernel modules automatically. Make sure you have the package 'blcr-dkms' installed (you should be able to check this by typing `dims status`.
Do either of those solutions solve your issue?

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:
