Derecho’s Acceptance Test Phase (ATP) was paused last week to allow HPE system engineers to focus on debugging the system and to resolve job launch failures, Slingshot network issues, and performance variability. While HPE has fully resolved the job launch failures, we continue to observe performance variability of select workloads and HPE is working to resolve the remaining performance issues. Additionally, the Derecho project team plans to conduct a final power cycle of the system before completing the ATP and prior to opening Derecho for Accelerated Scientific Discovery (ASD) access.
