Hi, We have developed a small RoR app that runs fine on a standard IBM thinkpad (1GB mem) but runsmuch slower when on an IBM x460 Redhat machine (32GB ram). The x460 server has hardly any thing running on it at present, so that not the issue. We are busy checking the config and permissions of the user account used to run the app., but I was wondering if you guys have heard anything about redhat and RoR, that maybe causing t...

...t the symmetry of NUMA systems w.r.t the sockets_per_node value. Details are available a later email with the patch. These patches have been tested on several IBM NUMA and non-NUMA systems: NUMA-aware systems: IBM Dual Opteron: 2 Node, 2 CPU, 4GB IBM x445 : 4 Node, 32 CPU, 32GB IBM x460 : 1 Node, 8 CPU, 16GB IBM x460 : 2 Node, 32 CPU, 32GB Non NUMA-aware systems (i.e, no SRAT tables): IBM Dual Xeon : 1 Node, 2 CPU, 2GB IBM P4 : 1 Node, 1 CPU, 1GB We look forward to your review of the patches for acceptance. -- Ryan Harper Software Engineer;...

...ntaining the patchset against unstable. Additionally, I''ve spent the past few weeks collecting some performance benchmarks comparing with and without the NUMA patches on a system configured as a 4-socket server(no NUMA characteristics) and as a multi-node 16-socket NUMA machine.

Hi, I am a Masters student from Carnegie Mellon University. I am looking for a research topics for an Advanced OS & DS course we have. I wanted to know what is the current support for NUMA on Xen ? Does it support the IBM x440 and AMD64 Opteron ? Also, does the Xen scheduler do NUMA aware scheduling so it does not degrade the VM performace ? My group is currently looking into Scheduling
