(Updated Dec. 16, 2014, 9:16 a.m.) Review request for Default. Repository: gem5 Description (updated) ------- Changeset 10606:3a4e0cb7ffe6 --------------------------- config: Add options to take/resume from SimPoint checkpoints More documentation at http://gem5.org/Simpoints Steps to profile, generate, and use SimPoints with gem5: 1. To profile workload and generate SimPoint BBV file, use the following option: --simpoint-profile --simpoint-interval <interval length> Requires single Atomic CPU and fastmem. <interval length> is in number of instructions. 2. Generate SimPoint analysis using SimPoint 3.2 from UCSD. (SimPoint 3.2 not included with this flow.) 3. To take gem5 checkpoints based on SimPoint analysis, use the following option: --take-simpoint-checkpoint=<simpoint file path>,<weight file path>,<interval length>,<warmup length> <simpoint file> and <weight file> is generated by SimPoint analysis tool from UCSD. SimPoint 3.2 format expected. <interval length> and <warmup length> are in number of instructions. 4. To resume from gem5 SimPoint checkpoints, use the following option: --restore-simpoint-checkpoint -r <N> --checkpoint-dir <simpoint checkpoint path> <N> is (SimPoint index + 1). E.g., "-r 1" will resume from SimPoint #0.
