See here: http://blog.xen.org/index.php/2012/04/26/numa-and-xen-part-1-introduction/ http://blog.xen.org/index.php/2012/05/16/numa-and-xen-part-ii-scheduling-an= d-placement/ For benchmarking our NUMA aware scheduling solution, in Xen, I used SpecJBB, sysbench and LMbench: http://blog.xen.org/index.php/2012/05/16/numa-and-xen-part-ii-scheduling-an= d-placement/ The trickiest part is have the benchmark(s) of choice running concurrently is a bunch of VMs on the same host. I used some hand crafted scripts at the time, very specific to my own environment. I'm working on abstracting that and putting together something more easy to be shared and used outside my attic. :-P Regards, Dario --=20 <> (Raistlin Majere) ----------------------------------------------------------------- Dario Faggioli, Ph.D, http://about.me/dario.faggioli Senior Software Engineer, Citrix Systems R&D Ltd., Cambridge (UK) --=-i50Dk+erqDRCabyQ4SpP Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) iEYEABECAAYFAlK0ZIwACgkQk4XaBE3IOsRR7wCfQ/T8h6m1DknPlY0+g1Bp0RNB cO8AnR1+v9xJoDvNQqWDxu4VDC5QIUOR =oQPk -----END PGP SIGNATURE----- --=-i50Dk+erqDRCabyQ4SpP--
