Most ACCESS MMS activities were devoted to effecting the transition from XMS, which supported XSEDE, to establishing ACCESS MMS and supporting the ACCESS launch. These activities included:
- writing the ACCESS MMS Project Execution Plan
- establishing the ACCESS MMS website
- participating in ACCESS committees and working groups
- supporting outreach to the CI community
- transitioning XDMoD to function within the ACCESS framework
Other activities included:
- routine maintenance on XDMoD and Open XDMoD
- preliminary work on the data analytics framework, the CI simulator and the ACCESS MMS service model
- initial work on tool development for tracking public cloud usage
A critical goal of the transition was to minimize disruption to the CI research community so that researchers were able to seamlessly utilize the CI resources within the ACCESS environment. To demonstrate this, ACCESS MMS leveraged XDMoD to provide a comparison of system usage and job throughput between XSEDE and ACCESS. The analysis included metrics such as number of jobs run, number of service units consumed, breakdowns of usage by resource, by type of user and by field of science. For example, shown below is a plot of the total number of XSEDE and ACCESS HPC users broken down by NSF role. In all cases, there was no measurable difference between CI usage under ACCESS compared to usage under XSEDE. However, our comparsion did note a decrease in Gateway-unique user reporting during the transition, which was subsequently tracked to issues with the gateway API usage for two of the gateways (zhanglab and Cipres) as opposed to an actual decrease in Gateway jobs. This has been corrected, and we're working to recover historical usage where possible.
