Hello Priya,
The portable way to determine the number of cpus _online_ is:
if [ -x /usr/bin/getconf ] ; then numprocs=$(/usr/bin/getconf _NPROCESSORS_ONLN) if [ $numprocs -eq 0 ]; then numprocs=1 fi else numprocs=1 fi
at least that is the number I usually pass to "make -j$numprocs" when compiling large software projects.
Regards, Tigran

But I would like to implement it using a system call rather than use the environment variables?? I couldn't find a system call for linux that would give me the result. Could anyone please let me know if there is one for redhat linux?? > > Thanks for your time, > Priya > - > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ >
