Hi! We are running a Dual-Opteron based Linux-Cluster with 20 nodes and SuSE90 AMD64. The cluster nodes are set up as diskless clients. The cluster is a batch-job cluster with Sun's gridengine. We are running C programs both in 32bit and in 64bit as well as Matlab jobs on it. Everything works fine. Details: 20xDual Opteron 242 1.6GHz, 6x1GB memory, MSI K8D Master F Mainboard, 80GB local HDD on each node The gateway uses an Infortrend EonStor external SCSI-Raid (~3TB in 3x1TB) and an Adaptec 39320D 2-channel SCSI Controller. Gigabit ethernet is used with an HP4108GL Switch. Problems only occured with the nameserver (which needed to be recompiled) and the kernel distributed on DVD which became unstable after about 3 hours of raid disc access (fdisk's harddisc check). But that's not the case with the currently available SuSE AMD64 kernel. The kernel was a problem quite a long time (at least until christmas) because the 2.6 test kernels had problems with the masquerading support which eventually cut off NFS connection and the 2.4 kernel had difficulties with the RAID as described above. The gridengine also did not work with every kernel which is a really strange problem because it does not depend on kernel modules but just uses the network interface.

Hi All,
Google shows some positive info about clusters on AMD64. However this maillist contains no feedbacks about clusters successfully running at AMD64 SUSE.
Is here anybody alive who has managed to setup such a cluster based on SUSE-AMD64?
Are there any technical notes/comments to read?
kind regards, Valery A.Khamenya
