I have done some stuff with SAS on clusters in the past. Are you looking for any particular feedback other than "it can be done"? Some of the issues/topics which would come up have to do with licensing on all nodes, the portability of SAS datasets between architectures, general data locality concerns for large datasets (and file locking over NFS), and the use of SAS/CONNECT for writing "parallel" SAS programs. -- Chris On 3/16/04 11:09 AM, "Steve Litster" <steve_litster@vrtx.com> wrote: > Is anybody using SAS on their cluster? > > Steve
