NUMA aware meminfo is one of the patches you have sitting in your tree. I haven't got around to the NUMA-sim yet ... maybe after Halloween when management stop asking me to get other bits of code in before the freeze ;-) mbligh@larry:~$ cat /proc/meminfo.numa Node 0 MemTotal: 4194304 kB Node 0 MemFree: 3420660 kB Node 0 MemUsed: 773644 kB Node 0 HighTotal: 3418112 kB Node 0 HighFree: 2737992 kB Node 0 LowTotal: 776192 kB Node 0 LowFree: 682668 kB Node 1 MemTotal: 4147200 kB Node 1 MemFree: 4116444 kB Node 1 MemUsed: 30756 kB Node 1 HighTotal: 4147200 kB Node 1 HighFree: 4116444 kB Node 1 LowTotal: 0 kB Node 1 LowFree: 0 kB Node 2 MemTotal: 4147200 kB Node 2 MemFree: 4131816 kB Node 2 MemUsed: 15384 kB Node 2 HighTotal: 4147200 kB Node 2 HighFree: 4131816 kB Node 2 LowTotal: 0 kB Node 2 LowFree: 0 kB Node 3 MemTotal: 4147200 kB Node 3 MemFree: 4128432 kB Node 3 MemUsed: 18768 kB Node 3 HighTotal: 4147200 kB Node 3 HighFree: 4128432 kB Node 3 LowTotal: 0 kB Node 3 LowFree: 0 kB >> Looks to me like it's just out of low memory: >> >> > LowFree: 1424 kB >> >> There is no low memory on anything but node 0 ... > > It was a GFP_HIGH allocation - just pagecache. Ah, but what does a balance_classzone do on a NUMA box? Once you've finished rototilling the code you're looking at, I think we might have a better clue what it's supposed to do, at least ...
