This depends: if you have a queuing system, the master node of a parallel job may be one of the slave nodes already where the jobscript runs. Nevertheless I have the nodes uniform, but I saw places where it wasn't the case. An option would be to have a special queue, which will execute the jobscript always on the headnode (i.e. without generating any load) and use only non-local granted slots for mpirun. For this it might be necssary to have a high number of slots on the headnode for this queue, and request always one slot on this machine in addition to the necessary ones on the computing node. -- Reuti > Sent from my iPad > > On Jan 24, 2012, at 5:54 AM, Ilias Miroslav <miroslav.il...@umb.sk> wrote: > >> Dear experts, >> >> following http://www.open-mpi.org/faq/?category=building#static-build I >> successfully build static OpenMPI library. >> Using such prepared library I succeeded in building parallel static >> executable - dirac.x (ldd dirac.x-not a dynamic executable). >> >> The problem remains, however, with the mpirun (orterun) launcher. >> While on the local machine, where I compiled both static OpenMPI & static >> dirac.x I am able to launch parallel job >> <OpenMPI_static>/mpirun -np 2 dirac.x , >> I can not lauch it elsewhere, because "mpirun" is dynamically linked, thus >> machine dependent: >> >> ldd mpirun: >> linux-vdso.so.1 => (0x00007fff13792000) >> libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f40f8cab000) >> libnsl.so.1 => /lib/x86_64-linux-gnu/libnsl.so.1 (0x00007f40f8a93000) >> libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007f40f888f000) >> libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f40f860d000) >> libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 >> (0x00007f40f83f1000) >> libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f40f806c000) >> /lib64/ld-linux-x86-64.so.2 (0x00007f40f8ecb000) >> >> Please how to I build "pure" static mpirun launcher, usable (in my case >> together with static dirac.x) also on other computers ? >> >> Thanks, Miro >> >> -- >> RNDr. Miroslav Iliaš, PhD. >> >> Katedra chémie >> Fakulta prírodných vied >> Univerzita Mateja Bela >> Tajovského 40 >> 97400 Banská Bystrica >> tel: +421 48 446 7351 >> email : miroslav.il...@umb.sk >> >> Department of Chemistry >> Faculty of Natural Sciences >> Matej Bel University >> Tajovského 40 >> 97400 Banska Bystrica >> Slovakia >> tel: +421 48 446 7351 >> email : miroslav.il...@umb.sk >> >> _______________________________________________ >> users mailing list >> us...@open-mpi.org >> http://www.open-mpi.org/mailman/listinfo.cgi/users > > _______________________________________________ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users >
