It is critical to performance engineering that we can investigate the efficiency of applications in utilizing hardware components. As new hardware technologies, including hardware accelerators and fast, non-volatile memory technologies emerge and be integrated into systems, it is essential that profiling tools must allow performance engineers to re-examine the interactions between applications and emerging hardware technologies.
Extreme Storage & Computer Architecture Laboratory (ESCAL) at UC Riverside led by Prof. Hung-Wei Tseng recently released two profiling tools — TPUPoint (https://github.com/escalab/
Tier Memory Profiler (TMP) is a tool released jointly by researchers from ESCAL (Jinyoung Choi and Hung-Wei Tseng) and AMD (Sergey Blagodurov). The IPDPS paper written by the authors of TMP also reveals that through TMP’s more complete understanding about the memory usage of big-data applications, the same memory allocation policy can work more efficiently. In other words, the profiling tool matters and probably even more than policies!
