hybridapplication_tau_aarch64.sif

Description

hybridapplication_tau_aarch64.sif is a singularity container based on ARM (aarch64). It can be used for profiling hybrid MPI on CPU based applications. This README showcases the usage of the container. It also lists the major softwares present in the container image for use.

Usage

In order to use this container follow the following steps:

Get the image from CDAC open source page
Once download is complete invoke the image shell using:

singularity shell hybridapplication_tau_aarch64.sif

Set the environment using:

source /usr/set_env.sh

The container is ready for use.

Using CUDA

Compiling cuda code

nvcc <program.cu>

Run the code

./a.out

Using CUDA with mpi

Compiling cuda with mpi code

nvcc -Xcompiler -fopenmp <program_name.cu> -o <program_name> -I$<OPENMPI_ROOT>/include -L$<OPENMPI_ROOT}/lib -lmpi -lgomp

Run the code

mpirun -np <no. of processes> ./<program_name>

Using TAU for profiling CUDA with mpi code

After compiling the CUDA + mpi code run the code as follows

mpirun -np <no. of processes> tau_exec ./<program_name>
pprof
