[CPMD-list] TCPU

[HW Sheng]

Greetings, all.

I am runing an ab intio job on a Linux/Alpha cluster. (10 dual Ev 6 alpha processors + 3com network switch + LAM). I noticed that the TCPU of the output is around 20 seconds (per step), but the real time almost doubles the number. Does that mean that half of the running time was wasted on the data transfer? Did this happen to you before? I used netPIPE to check the network performance, and nothing unusal was detected. Thanks for your input.
