If you tell openmpi mpirun --mca btl tcp,self -np a.out does that reduce the noise level? mpi apps tend to be very noisy because they poke the nics directly in memory, and memcheck doesn't understand what's going on. Also, did you try the flag --ignore-ranges=0xPP-0xQQ[,0xRR-0xSS] ? That was created expressly with the purpose of ignoring rances of memory into which nics have been mapped.
