Hi All, I was just curious, has anyone experience very bad performance issues/resultant timings with Amber 7/Sander running on a dual xeon 3.6 with ht and rhel 3 ws update 2? We have a cluster with that configuration and I have a user who says that he's seeing much slower performance than he was seeing on a Redhat 7.2 dual xeon 2.6 cluster. In addition to this question, has anyone seen any performance hits when using RHEL 3 and/or HT? I know for my own previous experiences, I've had to turn of HT on some of my customers clusters in order for their code to perform at expected performance. Anyone else experience something like this? Thanks, Brent
