[openib-general] IB: I don't like what I'm seeing. - large clusters

Thu Apr 8 14:04:02 PDT 2004

The Riken cluster you refer to is actually 3 clusters which can be joined.  Linux Cluster 1 consists of 512 nodes of Dual CPU Xeon systems with an Infiniband interconnect.  This cluster was installed by Fujitsu and InfiniCon.  We staged the cluster starting in 4th quarter of 2003 at Fujitsu, installed it at Riken in the first quarter of 2004, ran customer acceptance tests and opened it for business on 3/1/2004.  The cluster is performing genetics analysis and is running well.  Since its install, we have had no problem reports.

The staging process included extensive acceptance testing by both Fujitsu and the customer.  To give you a feeling of the degree of thoroughness in the testing, we had to ensure there were no finger prints on the units we shipped!  Our products were carefully tested and design reviewed by Fujitsu for data integrity, robustness, component selection, management interfaces, mechanical design, reliability and numerous other criteria.

I am not sure of the status of the other smaller Linux clusters at Riken.  I understand Linux cluster 2 is being provided by NEC and Topspin.  Linux cluster 3 is myranet.

I have a brochure which summarizes the clusters, but the mail server has rejected my attempts to attach it.

?? The link is to Fujitsu PR...  This cluster is the one also
described here: <>.  Maybe someone from
InfinCon can comment.
