During the week of March 13, the NWSC-3 project team continued resolving a myriad number of hardware and software issues encountered during the initial benchmark runs and NCAR team’s health checks. Later this week, the Spectrum Scale file system will be mounted on Derecho, allowing the consulting team to start building the software stack which will be used during the Acceptance Test Plan (ATP) to run NWSC-3 benchmark suites and other application-related tests. The ATP will commence when these issues have been resolved and Derecho's health checks can be successfully completed.
