Adding built-in support for basic performance test analytics to ReFrame

ReFrame is the tool of choice of many data centers and vendors alike when it comes to HPC cluster validation, ranging from small university clusters to large national supercomputers. Despite its highly capable test programming API and its feature-rich runtime, it has always delegated the post-processing of the test results to the user, requiring homegrown site-specific solutions for post-processing. In this talk we will present our recent contribution to ReFrame that enables support for basic analysis of past performance results. All the information about the test cases that have run in a session is stored in a backend database and a new set of CLI options are added for querying, analyzing and comparing past results. We will also discuss how we make use of this feature in our highly dynamic data center environment.
