<p align=left><font face=Arial size=2>Hi,</font></p> <p align=left> </p> <p align=left>I MS RDP into the Headnode and the compute maangement MMC to manage the compute clusters of two compute nodes + one headnode. However, after operating for a while, the headnode will become unreachable and my MMC will disconnect. Then, after a while, about 5 minutes, the headnode become reachable again.

All my three nodes (1 HN and 2 CN) have 8 cores, total: 24 cores. When I submit a job and choose 16 cores, everything run less than 1 minutes. When it goes beyond 16 cores, it seem to run forever? Anyway to tell where the compute cluster is hung at?</p> <p align=left> </p>© 2009 Microsoft Corporation.
