I'm using SCYLD beowulf (27Bz-7) with fair success. I have a couple of unrelated questions: I should point out that I'm only using 100MB ethernet through a 100MB ethernet switch. Also, the nodes are AMD athlon 1.4 GHz. 1. Does anyone have experience running GAMESS-US under Scyld? I'm running using the MPI version and I'm getting seemingly perfect scaling at 1.8x each time I double the number of processors. Has anyone had better experience? The author claims we should be getting nearly perfect doubling (using the sockets version) for a linux-ethernet cluster. 2. In upgrading to 27Bz-8 has anyone had any difficulty? Are there clear advantages for a network that is running ethernet? 3. Is there a simple bpsh command to remove all files from /tmp on the slave nodes? -- Arthur H. Edwards 712 Valencia Dr. NE Abq.
