I have ran fluent 14.5 on a cluster including 8 system with diferent number of cores and CPU frequencies (a 24 core with 3.67Ghz, a 16 core with 2.2 GHz, and 6 core with 2 Ghz)

when I read data up to 24 core,after case reading data will be read fast and CPU usage is more than 95, but when I use more than 24 cores( I test 40 and 80) data reading takes a very large time (about a day) and CPU usage fluctuates.

( I use 1G switch and cat5e cables and latency is low enough)

why? and what can I do?

regards
