Profiling applications for ARM HPC IT Department

ARM has a tiered storage architecture which makes it important to ensure that jobs and tool flows do not spend too long waiting while a file is fetched. Accessing the file system unnecessarily can slow down the network and affect other jobs.

Before tools and scripted flows are allowed to run on the main cluster, they are checked on a smaller practice cluster with Breeze. The initial benefits of using Breeze were seen immediately.

ARM is now able to sign off new flows more quickly and more safely.

Julien Palleau, Director of Engineering IT at ARM, said: “We are looking forward to catching problems before they happen by profiling our flows with Breeze. Long term we expect to see significant gains from more accurate prediction of our network and file system load and an overall reduction in traffic.”
