[OMPI users] wrong results in a heterogeneous environment with openmpi-1.6.2

2012-10-04 Thread Siegmar Gross
Hi, I have a small matrix multiplication program which computes wrong results in a heterogeneous environment with different little endian and big endian architectures. Every process computes one row (block) of the result matrix. Solaris 10 x86_64 and Linux x86_64: tyr matrix 162 mpiexec -np 4 -
