We got our POWER7 780 (MR) System on Friday and I just logged in :-). I’m alone on something like this:
htor@bd01:~> w 20:49:12 up 1 day, 1:01, 1 user, load average: 0.00, 0.00, 0.00 USER TTY LOGIN@ IDLE JCPU PCPU WHAT htor pts/0 20:35 0.00s 0.04s 0.01s w htor@bd01:~> cat /proc/cpuinfo processor : 0 cpu : POWER7 (architected), altivec supported clock : 3864.000000MHz revision : 2.1 (pvr 003f 0201) processor : 1 cpu : POWER7 (architected), altivec supported clock : 3864.000000MHz revision : 2.1 (pvr 003f 0201) ........ processor : 127 cpu : POWER7 (architected), altivec supported clock : 3864.000000MHz revision : 2.1 (pvr 003f 0201) timebase : 512000000 platform : pSeries model : IBM,9179-MHB machine : CHRP IBM,9179-MHB
It’s SMT=4 though (so “only” 32 cores) but with sweet 128 GiB memory. With 4 FMAs per cycle, that’s 983.04 GF/s, nearly one TF in a single “rack” (that thing below)!
I particularly like the name … we all hope that the drop will quickly fill up a bucket full of water(s) :-).
