Isn't the process manager infrastructure hetero-safe? At the very least, ssh-ing "uname -a" around the ring of procs can identify the problem on O(1) cost.

If we detect what the local architecture is, how will we communicate it to other processes without having some infrastructure that is hetergeneous-architecture safe? — Pavan On Jan 1, 2014, at 9:50 AM, Jeff Hammond <jeff.science(a)gmail.com> wrote: > One wonders if MPICH could verify the system was sufficiently homogeneous to function properly during initialization rather than defer detection to an error during communication calls. > > Jeff > > Sent from my iPhone > >> On Jan 1, 2014, at 8:07 AM, Matthias Neuer <mneuer(a)web.de> wrote: >> >> Am 31.12.2013 18:44, schrieb Pavan Balaji: >>> >>> On Dec 31, 2013, at 10:11 AM, Matthias Neuer <mneuer(a)web.de> wrote: >>> >>>>> On 12/31/2013 04:34 PM, Pavan Balaji wrote: >>>>> >>>>> Are matze-debian and notebook of the same architecture (x86_64 and running the same OS/configuration)? >>>> >>>> No, notebook is x86_32 on debian stable and matze-debian is x86_64 on debian testing, but I compiled the program for each system separately. >>> >>> Such heterogeneous configurations are not supported in mpich. >> >> Ok, thats the problem then.

One wonders if MPICH could verify the system was sufficiently homogeneous to function properly during initialization rather than defer detection to an error during communication calls.

Ok, thats the problem then. I didn't find that information in the FAQ or in the installation manual. Thanks for your help. Matthias

Hi, Lixin, Unfortunately, we have stopped supporting MPICH on windows. For the windows part, you will have to find it on your own. http://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions#Q:_Why_can… — Huiwei Lu On Dec 31, 2013, at 6:50 AM, Wesley Bland <wbland(a)mcs.anl.gov> wrote: > Please direct all questions to discuss(a)mpich.org. > > On Dec 31, 2013, at 7:26 AM, 88-lixin <88-lixin(a)163.com> wrote: > >> hello , you give the the answer that detect whether MPICH has been installed or not in the computer the last time, thanks very much!
