Yellowstone users who need to debug code at scales beyond 1024 cores, even up to full-machine runs, will have that opportunity soon. As part of CISL’s purchase of DDT, MAP, and Performance Reports, Allinea, developer of the DDT debugger, will facilitate the larger-than-usual runs by providing CISL with a modified license for one week.

To indicate your interest and needs, submit a large-scale debugging request using the CISL Special request form. State how many cores you will need, how many runs you anticipate, and when you are available to run the jobs. CISL staff will schedule the license modification once user preferences and availability are known.

The agreement with Allinea allows CISL to offer this “burst mode” for large-scale debugging only a few times per year, so the opportunities will be scheduled by CISL consultants throughout the year as user needs are identified.

When your Yellowstone job’s workload or need for memory isn’t uniform, or if you want to place frequently communicating tasks on the same node for efficiency, consider submitting a task geometry job. See the CISL web site to learn how to create a task geometry job script.
