Extending OMPT to support Grain Graphs - Dataset

This collection contains the dataset used for the paper "Extending OMPT to support Grain Graphs", by Peder Voldnes Langdal, Magnus Jahre, and Ananya Muddukrishna.<br>The dataset is created by processing the textual outputs of schedbench, taskbench, BOTS, and SPEC OMP2012, and writing the aggregated data to the CSV-files provided here.The abstract of the paper is included below:<br>The upcoming profiling API standard OMPT can describe almost all profiling events required to construct grain graphs, a recent visualization that simplifies OpenMP performance analysis. We propose OMPT extensions that provide the missing descriptions of task creation and parallel for-loop chunk scheduling events, making OMPT a sufficient, standard source for grain graphs. Our extensions adhere to OMPT design objectives and incur up to 2% overhead for BOTS and SPEC OMP2012 programs. Although motivated by grain graphs, the events described by the extensions are general and can enable cost-effective, precise measurements in other profiling tools as well.
