PGHPF is Running at ARSC

The Portland Group has kindly extended ARSC's license to use their HPF compiler until February 29th. Please contact Mike Ess if you have any problems or results from using pghpf. The instructions for using pghpf at ARSC were described in newsletter #65 (12/15/95).

Accessing 128 PEs at ARSC

It is not always possible to access 128 PEs in a predictable way now that the ARSC T3D is more active. To help with this access, after downtime this Tuesday, January 9th, we will open the 128PE, 5 minute NQS queue first and let all accumulated jobs (5 minutes or less) execute. Then when the 128 PE jobs are complete we will activate the other T3D queues.

So if you would like to execute on 128 PEs for less than 5 minutes, submit your NQS job before 5PM on Tuesday January 9th. This procedure is an experiment, and if it goes well we may make it a regular part of Tuesday downtime. If you have any questions about this please contact Mike Ess.

CUG Table of Contents

In last week's newsletter, I mentioned that the proceedings for the Alaska CUG were not yet available. Just this week, I received my copy and the table of contents of the proceedings is given below. If you would like a copy of some article, send a request to me and I'll mail it out. (These articles are not available though the CUG home page.)
