shmemcpy - symmetric memcpy

shmemcpy implements a point-to-point and broadcast memcpy capability using OpenSHMEM.

Installation Requirements

Dependencies:

• OpenMPI's OpenSHMEM implementation
• pkg-config
• cmake

Compilation

Build the library libshmemcpy.a without the test driver

• mkdir build
• cd build
• cmake ..
• make

Build the library libshmemcpy.a with test drivers shmemcpy_driver and shmemcpy_bcast_driver

• mkdir build
• cd build
• cmake -DTEST_DRIVER=ON ..
• make

Running Programs

Copy shmemcpy_driver on to a distributed file system. Change directory to the NFS directory that hosts shmemcpy_driver.

oshrun -n 2 ./shmemcpy_driver

This library is designed to be run on an HPC system that manages jobs using bulk synchronous workload managers: Slurm, PBS, etc.

Development Environment

• Raspberry Pi OS for CM5
• Slurm
• NFS
• UCX
