It sounds like your system has not enough memory.

Try running mpibench by hand...first the bandwidth test...

mpirun <mpi options> mpi_bench -- -e 1 -x1 -m 16 -i 1 -b 

Cachebench is allocating too much memory, reduce the number in user.defs
from 29 to 24.

To test blasbench, you need some blas libraries installed. You either
need reference blas, Goto blas or Intel MKL. Do you have any of these?
