Hi, this is per-zone/reclaim support patch set for memory controller (cgroup). Major changes from previous one is -- tested with 2.6.24-rc3-mm1 + ia64/NUMA -- applied comments. I did small test on real NUMA machine. My machine was ia64/8CPU/2Node NUMA. I tried to complile the kernel under 800M bytes limit with 32 parallel make. (make -j 32) - 2.6.24-rc3-mm1 (+ scsi fix) .... shows soft lock-up. before soft lock-up, %sys was almost 100% in several times. - 2.6.24-rc3-mm1 (+ scsi fix) + this set .... completed succesfully It seems %iowait dominates the total performance. (current memory controller has no background reclaim) Seems this set give us some progress. (*) I'd like to merge YAMAMOTO-san's background page reclaim for memory controller before discussing about the number of performance. Andrew, could you pick these up to -mm ? Patch series brief description: [1/10] ... add scan_global_lru() macro (clean up) [2/10] ... nid/zid helper function for cgroup [3/10] ... introduce per-zone object for memory controller and add active/inactive counter. [4/10] ... calculate mapper_ratio per cgroup (for memory reclaim) [5/10] ... calculate active/inactive imbalance per cgroup (based on [3]) [6/10] ... remember reclaim priority in memory controller [7/10] ... calculate the number of pages to be reclaimed per cgroup [8/10] ... modifies vmscan.c to isolate global-lru-reclaim and memory-cgroup-reclaim in obvious manner. (this patch uses functions defined in [4 - 7]) [9/10] ... implement per-zone-lru for cgroup (based on [3]) [10/10] ... implement per-zone lru lock for cgroup (based on [3][9]) Any comments are welcome.
