X-ScaleSolutions announces MVAPICH2-DPU MPI library v2024.04

X-ScaleSolutions is pleased to announce the release of its MVAPICH2-DPU MPI library v2024.04 to accelerate scientific applications using the NVIDIA BlueField DPU technology.

This release of the MVAPICH2-DPU MPI library offloads non-blocking point-to-point operations in addition to multiple non-blocking collective operations.  Offloading dense communication operations can provide significant benefits to the scientific applications running on HPC centers and Cloud environments. X-ScaleSolutions has demonstrated that the MVAPICH2-DPU is able to boost the performance of Alltoall by 87% and P3DFFT application by up to 24%. Similar boost in performance can also be harnessed by other non-blocking collectives and associated applications using these collectives.

A complete set of features of MVAPICH2-DPU v2023.04 release are as follows:

• Based on MVAPICH2 2.3.7, conforming to the MPI 3.1 standard
• Supports all features available with the MVAPICH2 2.3.7 release
• Novel frameworks to offload nonblocking collectives to DPU
• Offloads nonblocking Alltoall (MPI_Ialltoall) to DPU
• Offloads nonblocking Alltoallv (MPI_Ialltoallv) to DPU
• Offloads nonblocking broadcast (MPI_Ibcast)
• Offloads blocking send and receive (MPI_Send, MPI_Recv)
• Offloads noblocking send and receive (MPI_Isend, MPI_Irecv)
• Supports sub-communicator non-blocking collective offloading
• Supports multiple outstanding non-blocking collective operations per MPI rank offloading
• Optimized support for both Intel CPU-based and AMD CPU-based clusters with DPUs, respectively 
• Up to 99% overlap of communication and computation with non-blocking collectives 
• Accelerates scientific applications using any mix of MPI_Ialltoall, MPI_Ialltoallv, MPI_Ibcast, MPI_Isend, MPI_Irecv nonblocking collective and point-to-point communications
