2024-08-21Stream stats (#71)JRPan
* Temp commit for Justin and Cassie to sync on code changes for adding per-stream status. * Resolved compile errors. * Removed redundant parameter * Passed cuda_stream_id from accelsim to gpgpusim * Cleaned up unused changes * Changed vector to map, having operator problems. * StreamID defaults to zero * Implemented streams to inc_stats and so on * Fixed TOTAL_ACCESS counts * Implemented GLOBAL_TIMER. * Fixed m_shader->get_kernel SEGFAULT issue in shader.cc. * Use warp_init to track streamID instead of issue_warp * Removed temp debug print * Modified cache_stats to only print data from latest finished stream Added optional arg to cache_stats::print_stats, cache_stats::print_fail_stats and their upstream functions. When streamID is specified, print stats from that stream. When not specified, print all stats. NOTE: current implementation depending on streamid never equals -1 * Removed default arg values of streamID * modified constructor of mem_fetch to pass in streamID * changed get_streamid to get_streamID * Added TODO to gpgpusim_entrypoint.cc and power_stat.cc * Only collect power stats when enabled * print last finished stream in PTX mode using last_streamID * take out additional printf * Add a field to baseline cache to indicate cache level * save gpu object in cache * Print stream ID only once per kernel * rm test print * use -1 for default stream id * cleanup debug prints * remove GLOABL_TIMER * Automated clang-format * Should be correct to print everything in power model * addressing concerns & errors * Automated clang-format * add m_stats_pw in operator+ * Automated Format --------- Co-authored-by: Justin Qiao <[email protected]> Co-authored-by: Justin Qiao <[email protected]> Co-authored-by: Tim Rogers <[email protected]> Co-authored-by: JRPan <[email protected]> Co-authored-by: purdue-jenkins <[email protected]>

2024-06-22Add missing increment part for m_pending_ldgsts with minor fix (#72)Wonhyuk Yang
LDGSTS/LDGDEPBAR was introduced #62, but it's increment part was deleted by mistake. So add it. In some applications, ldgsts may not exist between ldgdepbar. In such cases, add exception handling logic to insert an empty vector. Reported-by: Okkyun Woo <[email protected]> Signed-off-by: Wonhyuk Yang <[email protected]>
