You should be able to add the blcr modules to the list of modules loaded at boot up by editing the file /etc/modules. Just add the names of the modules to the list. Wesley On May 1, 2013, at 1:08 PM, basma a.azeem <[email protected]> wrote:

Thank you so much for your help

i used "insmod" to install kernel module for blcr

"sudo insmod /usr/local/lib/blcr/3.5.0-27-generic/blcr_imports.ko" "sudo insmod /usr/local/lib/blcr/3.5.0-27-generic/blcr.ko"

it works but i need to run these commands every time i shut down i think that there is a method to have them installed permanently

i am new to Linux and parallel programming also

i need to find long running c/mpi applications to test blcr , the applications i will use to test blcr should have an enough long execution time , i found many applications but with a short execution time .

thank you

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?

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:

basma@basma-Satellite-A500:~$ mpiexec -ckpointlib blcr -ckpoint-prefix /home/business/ckpts/app.ckpoint -ckpoint-interval 3600 -n 4 /home/basma/libraries/mpich-3.0.3/examples/cpi
