comment Water-Cooled Rack Door: does it work well with Blades or GPU nodes?
it's a designated room of about 80 m^2 with no windows and a single AC (pretty weak, perhaps ~20 kW or so to keep a constant room temperature). there's a water supply that has enough capacity to provide cooling for ~100 kW. there are no strong space constraints.

comment ZFS performance: do I need to keep free space in a pool or a file system?
syneticon-dj, thank you for this explanation! Increasing RAM seems to help indeed.

comment ZFS: Why does resilvering go over all disks in a pool rather than only those in the raidz1 vdev?
Solaris 10 8/11. The resilvering is over by now, but I can tell you it was a disk inside raidz1-1. Thank you for the pointer to iostat, I will look into it next time I lose a disk. I'll also have to stop nfsd first in order to isolate the resilvering load from the usual load.

comment CUDA: Is it possible to dynamically restrict the number of cores / threads / clock freq. while a process is running on a GPU?
Thank you for your answer! You're right with everything you said, but I'm still looking for some technical details of how to perform the throttling. nvclock was a good start, but it seems that it doesn't support my video cards. Perhaps there are other ways?

Of course you're right, working cooling is absolutely important. Thank you for the pointer to nvclock!

Yes, this was the first thing I thought of, but unfortunately I can not modify the code to reduce the load. That's why I'm curious if it's possible to do this on the Linux kernel level (tell scheduler to give the process less shares?) or the CUDA driver (same idea).
