@@ -19,6 +19,9 @@ Version 3.2.1+edits (development branch) versus 3.2.1 - Removed the use of gcc in compilation and the need for a bunch of unnecessary 'extern "c"' statements. - Removed print at kernel finish that dumped a warp issue histogram. +- Added new option '-liveness_message_freq'. It throttles the number of + simulation liveness messages printed by the timing model (defaults to + 1 message per second in wall clock time). - Bug Fixes: - Fixed the flit count sent to GPUWattch for atomic operations. - Fix for Bug 51 - Updated the function declaration of diff --git a/src/gpgpu-sim/gpu-sim.cc b/src/gpgpu-sim/gpu-sim.cc index dcbdfe0..2de9a4f 100644 --- a/src/gpgpu-sim/gpu-sim.cc +++ b/src/gpgpu-sim/gpu-sim.cc @@ -378,6 +378,9 @@ void gpgpu_sim_config::reg_options(option_parser_t opp) option_parser_register(opp, "-gpgpu_runtime_stat", OPT_CSTR, &gpgpu_runtime_stat, "display runtime statistics such as dram utilization {<freq>:<flag>}", "10000:0"); + option_parser_register(opp, "-liveness_message_freq", OPT_INT64, &liveness_message_freq, + "Minimum number of seconds between simulation liveness messages (0 = always print)", + "1"); option_parser_register(opp, "-gpgpu_flush_l1_cache", OPT_BOOL, &gpgpu_flush_l1_cache, "Flush L1 cache at the end of each kernel call", "0"); @@ -571,6 +574,8 @@ gpgpu_sim::gpgpu_sim( const gpgpu_sim_config &config ) m_last_cluster_issue = 0; *average_pipeline_duty_cycle=0; *active_sms=0; + + last_liveness_message_time = 0; } int gpgpu_sim::shared_mem_size() const @@ -1268,17 +1273,20 @@ void gpgpu_sim::cycle() time_t curr_time; time(&curr_time); unsigned long long elapsed_time = MAX(curr_time - g_simulation_starttime, 1); - days = elapsed_time/(3600*24); - hrs = elapsed_time/3600 - 24*days; - minutes = elapsed_time/60 - 60*(hrs + 24*days); - sec = elapsed_time - 60*(minutes + 60*(hrs + 24*days)); - printf("GPGPU-Sim uArch: cycles simulated: %lld inst.: %lld (ipc=%4.1f) sim_rate=%u (inst/sec) elapsed = %u:%u:%02u:%02u / %s", - gpu_tot_sim_cycle + gpu_sim_cycle, gpu_tot_sim_insn + gpu_sim_insn, - (double)gpu_sim_insn/(double)gpu_sim_cycle, - (unsigned)((gpu_tot_sim_insn+gpu_sim_insn) / elapsed_time), - (unsigned)days,(unsigned)hrs,(unsigned)minutes,(unsigned)sec, - ctime(&curr_time)); - fflush(stdout); + if ( (elapsed_time - last_liveness_message_time) >= m_config.liveness_message_freq ) { + days = elapsed_time/(3600*24); + hrs = elapsed_time/3600 - 24*days; + minutes = elapsed_time/60 - 60*(hrs + 24*days); + sec = elapsed_time - 60*(minutes + 60*(hrs + 24*days)); + printf("GPGPU-Sim uArch: cycles simulated: %lld inst.: %lld (ipc=%4.1f) sim_rate=%u (inst/sec) elapsed = %u:%u:%02u:%02u / %s", + gpu_tot_sim_cycle + gpu_sim_cycle, gpu_tot_sim_insn + gpu_sim_insn, + (double)gpu_sim_insn/(double)gpu_sim_cycle, + (unsigned)((gpu_tot_sim_insn+gpu_sim_insn) / elapsed_time), + (unsigned)days,(unsigned)hrs,(unsigned)minutes,(unsigned)sec, + ctime(&curr_time)); + fflush(stdout); + last_liveness_message_time = elapsed_time; + } visualizer_printstat(); m_memory_stats->memlatstat_lat_pw(); if (m_config.gpgpu_runtime_stat && (m_config.gpu_runtime_stat_flag != 0) ) { diff --git a/src/gpgpu-sim/gpu-sim.h b/src/gpgpu-sim/gpu-sim.h index 90f8cb6..03f9bf2 100644 --- a/src/gpgpu-sim/gpu-sim.h +++ b/src/gpgpu-sim/gpu-sim.h @@ -347,6 +347,7 @@ private: + unsigned long long liveness_message_freq; friend class gpgpu_sim; }; @@ -462,6 +463,7 @@ private: unsigned long long gpu_tot_issued_cta; unsigned long long last_gpu_sim_insn; + unsigned long long last_liveness_message_time; std::map<std::string, FuncCache> m_special_cache_config; |
