Hi Siegmar, It seems you already enabled the most detailed error outputs. We could not think out any clue for now. If you can give us access to your machine, we are glad to help you debug on it. Min On 10/8/15 12:02 AM, Siegmar Gross wrote:

Hi Min,

thank you very much for your answer.

We cannot reproduce this error on our test machines (Solaris i386, Ubuntu x86_64) by using your programs. And unfortunately we do not have Solaris Sparc machine thus could not verify it.

The programs work fine on my Solaris x86_64 and Linux machines as well. I only have a problem on Solaris Sparc.

Sometime, it can happen that you need to add "./" in front of the program path, could you try it ?

For example, in spawn_master.c MPI: A Message-Passing Interface Standard

...

#define SLAVE_PROG "./spawn_slave"

No, it wil not work, because the programs are stored in a different directory ($HOME/{SunOS, Linux}/{sparc, x86_64}/bin) which is part of PATH (as well as ".").

Can I do anything to track the source of the error?

Kind regards

Siegmar

Hi,

today I've built mpich-3.2rc1 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. I still get the following errors on my Sparc machine which I'd already reported September 8th. "mpiexec" is aliased to 'mpiexec -genvnone'. It still doesn't matter if I use my cc- or gcc-version of MPICH.

I would be grateful if somebody can fix the problem. Thank you very much for any help in advance. I've attached my programs. Please let me know if you need anything else.

Kind regards

Siegmar
