CSX加速器應用在HPCC的效能評估

Abstract

由歷年全球前五百大超級電腦排名中，可以觀察到利用加速器之特性應用於提升運算效能趨勢。本研究採用現有該類解法，由其中選擇一具優勢者，進行其效能評估，並進一步提出改善建議。於傳統上，我們藉由HPL程式來量測高效能系統所產生之計算量。由於系統之多樣化發展。我們有必要更進一步針對電腦系統中，各項元件以不同程式來識別該系統之特性。HPCC為近年來針對處理器、快取記憶體、系統記憶體以至於內部網路連結等，透過不同程式之結果來觀察系統對各種不同性質之計算做出效能上之評量。我們研究將HPCC程式在一般伺服器搭配CSX加速器的系統上進行效能分析，並試圖獲得最佳化結果。同時，建議未來加速器設計上改良之方向。由本研究我們得知加速在HPC領域中應用之特性與其限制用途。

From the lists of the world’s Top 500 Supercomputers in the past years, we can see the tendency of employing the characteristics of accelerators to enhance operating performance. This research adopts the current solution, choosing one of the superior accelerators to evaluate its performance and further to offer the suggestions of improvement. Traditionally, we measure the computation power in the high performance system by HPL program. However, because of the diverse development of systems, we need to further focus on the characteristic that each item uses different programs to distinguish its system. HPCC has been used in recent years to evaluate performance by observing the system’s various computations on the processor, cache system, memory, the interconnection and so on, through the results of using different programs. We used the HPCC Suite to investigate the system performance of a common server with the CSX accelerator and we tried to obtain the optimal result. At the same time, we also made suggestions about future direction of improving accelerators. Through this study, we learned about the characteristics of applying accelerators in the HPC domain and its suitability.
