Nice :) good work!i
I was first puzzled by the cpu00 cpu-usage but then in the ps i saw that you
were tar'ing with gz, and that explained it ;)
What is the current status? Have you made progress since this posting? Do you
take the physical connectivity into account when sheduling? Or are you using
processor affinity as much as possible?
I did read somewhere that the individual CPUs lack floating-point hardware, is
that true? How much would that effectively hurt general purpose applications?
With regards and keep on hacking!
