Performance and Power Analysis of HPC Workloads on Heterogeneous Multi-Node Clusters

Abstract: Performance analysis tools allow application developers to identify and characterize the inefficiencies that cause performance degradation in their codes, allowing for application optimizations. Due to the increasing interest in the High Performance Computing (HPC) community towards energy-efficiency issues, it is of paramount importance to be able to correlate performance and power figures within the same profiling and analysis tools. For this reason, we present a performance and energy-efficiency study aimed… Show more

“…We plan to extend this work also to the second release of the ThunderX chip which is expected to be widely adopted in the HPC market [8] and moreover we expect to be able to access also non-standard power related registers embedded in this SoC [7], as done for other architectures [36]. The possibility to read power figures using PAPI [37], would enable also fine grained energy analyses [29], [38] without the need for external power-meters [39].…”

“…Popular tools to read the PMCs on a given platform include Likwid [47], Linux Perf [48], PAPI [43] and Intel PCM [42]. Extrae and Paraver tools [49,50] can also be used to gather the PMCs. These tools are built on top of PAPI.…”
