If Sun==Solaris then $ psrinfo -p should give you the number of physical processor and $ uname -X | grep NumCPU the total number of core see http://www.sunsolarisadmin.com/general/psrinfo-find-number-of-physical-virtual-processors-in-solaris-10/ On IRIX; $ hinv | grep -i processor see: http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi?coll=hdwr&db=bks&fname=/SGI_EndUser/Octane2_Dual_Head_IG/apa.html On HP-UX: $ machinfo | grep -i CPUs | awk '{print $5}' see : http://forums11.itrc.hp.com/service/forums/questionanswer.do?admit=109447626+1289241355098+28353475&threadId=1287278 On FreeBSD: $ sysctl hw.ncpu If you want wider support for several platforms there is hwloc: http://www.open-mpi.org/projects/hwloc/ which does a pretty good job. hwloc-info --merge + some grep and arithmetic should do the job. but I'm afraid hwloc is not of widespread use unless for platform where OpenMPI is used. If using hwloc is not an option then have a look to "hwloc_fallback_nbprocessors" inside hwloc/src/topology.c you'll find some methods used to find the number of CPUs. -- Erk Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org _______________________________________________ cmake-developers mailing list cmake-developers@cmake.org http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
