It is a dual Xeon (Quad core) on a 5000P chipset board.
Tziporet> Can you send us description how to reproduce?
I started a 100 node / 8 core = 800 processes mvapich job
(linpack). The issue occured after about 1 hour of runtime. A 50 node
/ 8 core = 400 processes mvapich job ran fine several times for more
than 36 hours (including the node on which this issue occured now).
