[mpich-discuss] BLCR kernel module not present

[Wesley Bland]

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?
