##Introduction:

Tartan is a multi-GPU benchmark suite. It is proposed to evaluate modern GPU interconnect in our IISWC-18 paper "Tartan: Evaluating Modern GPU Interconnect via a Multi-GPU Benchmark Suite". Please see our paper (as included) for more details.

Tartan contains three sub-directories:

microbenchmark The microbenmarking routines to measure the startup latency, sustainable uni-/bi-direction bandwidth, bandwidth with message size, etc. for Peer-to-Peer (P2P) and and Collective Communication (CL) on PCI-e, NVLink-V1, NVLink-V2 and InfiniBand.

scale-up Applications for intra-node scale-up (i.e., single node with multiple GPUs)

scale-out Applications for inter-node scale-out (i.e., GPU-accelerated multi-node system)

##Acknowledge:

The applications in Tartan were modified from their original implementations. It is an joint effort of the community. Here we list the source of the original design.

The Tartan Benchmark Suite and the evaluation research was supported by the U.S. DOE Office of Science, Office of Advanced Scientific Computing Research, under award 66150: "CENATE - Center for Advanced Architecture Evaluation". The Pacific Northwest National Laboratory is operated by Battelle for the U.S. Department of Energy under contract DE-AC05-76RL01830. This research was also supported by the Exascale Computing Project (17-SC-20-SC), a collaborative effort of the U.S. DOE Office of Science and National Nuclear Security Administration. Part of the computing resources is from the Oak Ridge Leadership Computing Facility. The Oak Ridge National Laboratory is supported by the Office of Science of the U.S. Department of Energy under Contract No. DE-AC05-00OR22725.
