The following code has proved good to generate a crash using MKL 10.2 update 2 (sequential version and threaded), last revision of MVAPICH, in two different clusters. Can anybody tell me what the problem is here? It does not crash always, but it does crash when the right number of MPI processes and matrix sizes are selected.
* crash.cpp - crashes with ICC 11.1, MKL 10.2, MVAPICH 1.0 on linux 64-bit
* both linked with the serial or threaded libraries
* doing mpirun -np 36 crash 5000 10
