These benchmarks are often used for comparing different Message Passing Inerface (MPI) implementations and the underlying network interconnect. Here we use the OSU micro-benchmark (version 7.2) to assess the performance in terms of bandwidth achieved with an Apptainer container between 2 processors on different nodes with OpenMPI (version 4.1.6) on the Norwegian academic High Performance Computers (HPC) located in Tromsø (Fram) and Trondheim (Betzy). https://w3id.org/ro-id/97b0167c-0cb4-457d-abe8-41d1a9d1b981/

an open-source implementation of the MPI-3 standard that is developed and maintained by collaborators from academia, industry, and national laboratories. Oak Ridge National Laboratory (ORNL) and Los Alamos National Laboratory (LANL) are collaborating on porting and optimizing Open MPI and related components for use on HPE Cray EX systems, with a focus on the DOE Frontier and Aurora exa-scale systems. A key component of this effort involves development of a new LinkX Open Fabrics Interface (OFI) provider. In this paper, we describe enhancements to Open MPI, OpenPMIx runtime components, and the LinkX OFI provider. Performance results are presented for point to point and collective communication operations using both the vendor CXI provider and the LinkX provider, including results obtained using GPU accelerators. Recommended deployment options for EX systems will be discussed, along with future work. https://www.osti.gov/servlets/purl/1997634 http://schema.org/keywords Slingshot 11 https://www.osti.gov/servlets/purl/1997634 http://schema.org/keywords libfabric https://www.osti.gov/servlets/purl/1997634 http://schema.org/license https://choosealicense.com/no-permission/ https://www.osti.gov/servlets/purl/1997634 http://schema.org/name Open MPI for HPE Cray EX Systems https://www.osti.gov/servlets/purl/1997634 http://schema.org/sdDatePublished 2024-01-17 10:54:09.114061+00:00 https://www.osti.gov/servlets/purl/1997634 http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://purl.org/wf4ever/wf4ever#Resource https://www.osti.gov/servlets/purl/1997634 http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://schema.org/MediaObject https://www.osti.gov/servlets/purl/1997634 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/ro/terms/earth-science#ConferencePaper https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8/provenance https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8/assertion http://www.w3.org/ns/prov#wasDerivedFrom https://api.rohub.org/api/ros/97b0167c-0cb4-457d-abe8-41d1a9d1b981/crate/download/ro-crate-metadata.json https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8/pubinfo https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8 http://purl.org/dc/terms/created 2026-03-03T15:15:44.181+01:00 https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8 http://purl.org/dc/terms/creator https://w3id.org/kpxl/gen/terms/RoCrateBot https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8 http://purl.org/nanopub/x/introduces https://w3id.org/ro-id/97b0167c-0cb4-457d-abe8-41d1a9d1b981/ https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8 http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://purl.org/nanopub/x/RoCrateNanopub https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8 http://www.w3.org/2000/01/rdf-schema#label OSU MPI Get Bandwidth Test v7.2 with OpenMPI 4.1.6 on Fram & Betzy https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8/sig http://purl.org/nanopub/x/hasPublicKey MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxszSDYX5tuCSkP7UiCtftYPFNQVTjgNu0I5fwdML2DLRDlp0xzmsQXRk8oHuvwGvG1aMjj6cpUqO+0rz2Sg/wvHOgUpkRH8VJXvmlkhafMLCMtUtk5JIx7e+fkzCby+fnmD7kMkGLrT+OaExWwEDmNlCAt0TPKcHSdwsjso2isXjtAsGevyCMke8ufnFYpjs746JES1eNzVnHnn2Kp/lqcm60GM+J8dLgRZp7fX0anW098xhKym6+xXFzqeju0vYRIHBPerv+r7skWxwk+a7Sd8msqVeYEv6NTqnyWvyWb6Yh8cvj04N6qm/T6C5FUPLQhzSaQgMVMU6yLqjPuu9DwIDAQAB https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8/sig http://purl.org/nanopub/x/hasSignature VKbxj4o74UWPK2L+apSYP/8k+oJZ8L5XAALPqMSTgDTBTjKa/I2TX5QLxA4efh0IGC8TvvX7EkH0z46LDbAwrZNeTaISBUMBMlyckrubIu3UD5ZcmMU/Po5/HJi6Vtb2emiqeM7sfDYwAdqOqersAvk6bn7OJQDPd6fLkWfyajRQnSl17QxCeiLhkGc20hB36mXXsRmrs+r7XgzjDDguC+8C47mxx65ppvVzYwpYM8vVx2lqnrXXt1nz/gZ0mT6GWJdPaXyljsg3BYi0J7GqzAI2NOE2WQxnp9JnMDD0A/PnUH5WRdQy5Qf2smY5zl8/Ek4MCOe5H6ok/nHbK4CM0w== https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8 https://w3id.org/np/RAsdD7UML0Sw6I9APeXRiWbQKIKnYCBbN6bQT_FTzDrO8/sig http://purl.org/nanopub/x/signedBy https://w3id.org/kpxl/gen/terms/RoCrateBot
