I've done a bit more digging around, and it doesn't seem like much fun to try to parse /proc/cpuinfo in a portable way. *However*, it turns out glibc already does this! sysconf(_SC_NPROCESSORS_CONF) should work on x86, sparc, alpha, mips and, probably, ia64. -- Leif Nixon Systems expert ------------------------------------------------------------ National Supercomputer Centre Linkoping University ------------------------------------------------------------
