Configure Run Options We implement consistent options for each benchmark instance. Common options are: option value function -h none display the help message -t integer configure the number of threads to run -r integer configure the number of rounds to run -m string configure the baseline models to run, tbb, omp, or tf
You can configure the benchmarking environment by giving different options. Specify the Run Model In addition to a Taskflow-based implementation for each benchmark instance, we have implemented two baseline models using the state-of-the-art parallel programming libraries, OpenMP and Intel TBB, to measure and evaluate the performance of Taskflow. You can select different implementations by passing the option -m. ~$./bench_graph_traversal-mtf#runtheTaskflowimplementation(default) ~$./bench_graph_traversal-mtbb#runtheTBBimplementation ~$./bench_graph_traversal-momp#runtheOpenMPimplementation Specify the Number of Threads You can configure the number of threads to run a benchmark instance by passing the option -t. The default value is one. #runtheTaskflowimplementationusing4threads ~$./bench_graph_traversal-mtf-t4 Depending on your environment, you may need to use taskset to set the CPU affinity of the running process. This allows the OS scheduler to keep process on the same CPU(s) as long as practical for performance reason. #affinetheprocessto4CPUs,CPU0,CPU1,CPU2,andCPU3 ~$taskset-c0-3bench_graph_traversal-t4 Specify the Number of Rounds Each benchmark instance evaluates the runtime of the implementation at different problem sizes. Each problem size corresponds to one iteration. You can configure the number of rounds per iteration to average the runtime. #measuretheruntimeinanaverageof10runs ~$./bench_graph_traversal-r10 |V|+|E|Runtime 20.109#theruntimevalue0.109isanaverageof10runs 8420.298 ...... 61980273.135 66477174.436
