title: Artifacts for "CPU- and GPU-initiated Communication Strategies for Conjugate Gradient Methods on Large GPU Clusters"

description: This dataset contains computational artifacts related to the paper: “CPU- and GPU-initiated Communication Strategies for Conjugate Gradient Methods on Large GPU Clusters”

The paper describes computational experiments that were conducted to evaluate the performance of multi-GPU iterative linear solvers based on the conjugate gradient (CG) method.

The computational artifacts are located in several subdirectories:



'aCG-1.0.0/' contains the source code for aCG (version 1.0.0), which implements of the various multi-GPU CG solvers that are used for the performance benchmarks presented in the paper.

'partitions/' contains input files related to partitioning and distributing matrices that were used in the experiments. Partitions were computed using METIS (Karypis and Kumar, 1998), a multilevel graph partitioner.  From the SuiteSparse Collection (Davis and Hu, 2011), six matrices were selected: Bump_2911, Cube_Coup_dt6, Flan_1565, Queen_4147, Serena and audikw_1.  For each matrix, partitions are provided for 2, 4, 8, 16 and 32 parts.

'scripts/' contains job scripts for submitting jobs on three clusters: LUMI, MareNostrum 5 and Wisteria/BDEC-01 (Aquarius). These scripts carry out performance measurements for the multi-GPU CG solvers in aCG and PETSc, and were used to collect the results presented in the paper.

'results/' contains results from the performance benchmarks presented in the paper as tables in a plain-text format.
