Hi Siegmar, It seems it is still caused by the unaligned memory access issue in MPICH. Unfortunately, the fix patch is still in our reviewing queue. I hope it can be pushed to master as soon as we can. Please check this ticket for tracking the status (it will be closed once we have pushed fix to master). Thanks. https://trac.mpich.org/projects/mpich/ticket/2309 Min On 6/8/16 1:14 AM, Siegmar Gross wrote:
Hi,
I have built mpich-master-v3.2-331-g44fd9c5f39e5 on my machines (Solaris 10 Sparc, Solaris 10 x86_64, and openSUSE Linux 12.1 x86_64) with gcc-5.1.0 and Sun C 5.13. Most of the time I get an error with different error messages spawning processes on a Sparc machine.

I would be grateful if somebody can fix the problem. Please let me know, if you need more information. Thank you very much for any help in advance.
Kind regards
