2025-02-18A bunch of maintenance fixes, the largest of which is getting the PTX ↵Tim Rogers
simulation to work with CUDA 12. (#95) * Fixing the formatter to always use a consistent format and running it on the codebase * Update linux-so-version.txt * Update Makefile * A couple of unnecessary files that are lingering around * Support CUDA 12 * Getting the PTX simulations to work with CUDA 12. The issue is that ptxas added more information (number of barriers and compile time). We have to parse these or lexx/yacc fail. * Update ptxinfo.l debug MACRO was ineffective * Update gpgpusim_check.cmake Update to make the CUDA version print a warning, not an error and updating the print to be more reflective of what the actual problem is.

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]>
