MPI-Adapter2: An Automatic ABI Translation Library Builder for MPI Application Binary Portability

This paper proposes an automatic MPI ABI (Application Binary Interface) translation library builder named MPI-Adapter2. The container-based job environment is becoming widespread in computer centers. However, when a user uses the container image in another computer center, the container with MPI binary may not work because of the difference in the ABI of MPI libraries. The MPI-Adapter2 enables to building of MPI ABI translation libraries automatically from MPI libraries. MPI-Adapter2 can build MPI ABI translation libraries not only between different MPI implementations, such as Open MPI, MPICH, and Intel MPI but also between different versions of MPI implementation. We have implemented and evaluated MPI-Adapter2 among several versions of Intel MPI, MPICH, MVAPICH, and Open MPI using NAS parallel benchmarks and pHEAT-3D, and found that MPI-Adapter2 worked fine except for Open MPI ver. 4 binary on Open MPI ver. 2 on IS of NAS parallel benchmarks, because of the difference in MPI object size. We also evaluated the pHEAT-3D binary compiled by Open MPI ver.5 using MPI-Adapter2 up to 1024 processes with 128 nodes. The performance overhead between MPI-Adapter2 and Intel native evaluation was 1.3%.
