HP-MPI mpich troubles i786 linux 32 bit PARA_ARCH=MPI
« on: June 22, 2010, 08:32:59 pm »
We've downloaded ex novo the new binaries of TM6.2, after the patches were released and deleted the old TM6.2 dir, however we're experiencing problems when running TM in parallel via the MPI PARA_ARCH, which, to the best of our knowledge, is the only parallel platform available on 32-bit linux .

Attached are excerpta from dscf.statistics.parallel to show the version of TM6.2 at our disposal and from dscf.out files tho show the error message. The last  seems to suggest that the mpich executable from the new HP-MPI release does not work on our cluster. We add that we tested the dscf module in serial mode also and it appears to work fine. For our tests we used some old inputs which went fine w. TM5.10, TM6.0 and TM6.1 versions, properly installed and perfectly working on our 32-bit cluster. We also wish to add that both TM61 and TM62 sysname scripts automatically assign i786 to our cluster without any forcing and that environment variables were set to the dir of TM6.2  and the system was rebooted before executing the tests.

Any help will be appreciated. Thanks in advance

Hi,

I just want to mention it once more: This Forum is the Turbomole user forum, it is not the Turbomole support. So if you have technical problems please just contact the support. There you will get all the help you need - and you would help other users too, since the support team at COSMOlogic can find bugs, fix them and send patches to everyone  ;)

Regards,

Uwe

Dear Uwe,

I'm sorry for my post, but I really couldn't know in advance if i was faced with a possible bug of the HPMPI bundled in TM,  with technical problem or, on the opposite, if I was missing something maybe in the installation, so that other users could be of help. I will post to Cosmologic my problem as soon as possible.

Thank you anyway.

Amedeo
