Interesting, we are using 3.0 that is in MOFED, and that is also what is on the
MXM download site. Kinda confusing.

Hello Brock,
Some people complained that giving world-wide access to a device file by
default might be bad if we ever find a security leak in the kernel
module. So I needed a better default. The rdma group is often used for
OFED devices, and OFED and KNEM users are often the same, so it was a

I'm not sure why this is the default but in your case you should set the
permissions to 666 to use it.

Hi,
KNEM can improve the performance significantly for intra-node communication
and that's why MXM is using it.
If you don't want to use it, you can suppress this warning by adding the
following to your command line after mpirun:
-x MXM_LOG_LEVEL=error
