Henk,

Does the ldd output of the executable list myriexpress as a dependancy?

If so, was your Open-MPI built to always link libmyriexpress? By default, it should not.

Dear Scott

The MX library is dynamically linked in the executable.

In the mean time I repeated this with a simple MPI program which gives
the same messages about mx_init but does not crash. In the crashing
program the segmentation error came directly after the MX error and I
assumed they might be related but they are probably not.
The program that fails is tough2_mp with the Aztec library, however
building it with mpich_mx instead of OpenMPI does not give problems.

Thanks

Henk

Although the mismatch between MX lib version and the kernel version

Thanks in advance for any advice to solve this

Henk,

Is MX statically compiled into the binary or Open-MPI library?

Scott
