Cole, Thanks for the patch, looks good. I believe best fit is a good choice. For our NUMA systems, we want to fully utilize a single node before moving work to a second node as to minimize the amount of memory traffic over the interconnects. Best-fit should do this by selecting cell with the least amount of free ram that satisfies the request. What's the best RH-flavor'ed platform for testing this patch out? Fedora8, RHEL5u1? -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx (512) 838-9253 T/L: 678-9253 ryanh@xxxxxxxxxx _______________________________________________ et-mgmt-tools mailing list et-mgmt-tools@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/et-mgmt-tools
