Summary: | In previous work, we developed a checkpoint compression viability model based on compression factor, compression speed and I/O bandwidth that outputs when checkpoint data compression yields performance improvements. We evaluated the impact of checkpoint compression on overall application performance using an extension of Daly's model. This evaluation was based on CPU-based checkpoint compression performance and demonstrated that checkpoint data compression can improve an application makespan significantly. Now, we compare compression-based and increment-based optimizations and begin to explore how GPU-based checkpoint compression might further improve checkpoint/restart performance. |
