Building

Setup spack and sds-repo, clone this repository and cd in it, then:

spack env create ssg-test spack.yaml
spack env activate ssg-test
spack install
spack env deactivate

Then to build the code:

export CRAYPE_LINK_TYPE=dynamic
module swap PrgEnv-intel PrgEnv-gnu
module swap gcc/8.3.0 gcc/9.3.0
spack env activate ssg-test
mkdir build
cd build
cmake ..
make

Running

From the build directory:

export MPICH_GNI_NDREG_ENTRIES=1024
export HG_NA_LOG_LEVEL=debug
export ABT_THREAD_STACKSIZE=2097152
srun -C haswell -n 128 ./test-server
# one of the server will print "Credential: X", copy the X

In another terminal window, with current working directory set to build:

export MPICH_GNI_NDREG_ENTRIES=1024
export HG_NA_LOG_LEVEL=debug
export ABT_THREAD_STACKSIZE=2097152
srun -C haswell -n 1 ./test-client X # replace X with the copied value
