Actually, it is pretty stable. It OOM's a bit more easily, but that isn't a surprise to anyone, especially with the smaller amount of ZONE_NORMAL. I routinely run kernel compiles for days on it with no problems.
That is, of course, a NUMA-Q. We're hoping to get a Summit box which is just as big sometime soon. It will be much more interesting. -- Dave Hansen haveblue@us.ibm.com
