original centos kernel is 2.6.18. anyhow, i found a RHEL bug (which centos is based on): https://bugzilla.redhat.com/show_bug.cgi?id=518581 comment #1 from this bug: It has only been added to glibc 2.6, and cannot be backported due to ABI breakage. You can always fall back to syscall(3). so, RHEL/CentOS 5 will never support this directly. what about implementing the mentioned "syscall(3)" workaround for RHEL/ CentOS? - Thomas ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
