There is a ch_shmem transport option in mpich which might suit your needs. Please try building this option, by taking the mpich package and editing debian/rules line 30, replacing: --with-device=ch_p4 with: --with-device=ch_shmem If this works, then after the next bugfix release gets into testing, I will upload a new version which builds an additional set of -shmem packages to finally close this bug. But since that will go into the NEW queue, it will probably take quite a while to get into the archive...
