hpcpp's Introduction

hpcpp

Standard C++26 High-Performance Computing (HPC) applications that run on CPUs and GPUs.

Build

git clone https://github.com/NERSC/hpcpp.git
cd hpcpp; mkdir build ; cd build
ml nvhpc/23.7 cmake 3.24

# enable GPU support by setting -DSTDPAR=gpu (default)
cmake .. -DSTDPAR=<gpu/multicore> -DOMP=<gpu/multicore; 
make -j 10

Note: Make sure your localrc file (located at /path/to/nvhpc/bin) is properly configured to GCC >= 11.2.0 paths.

NERSC Users

You can also use the pre-configured localrc file included in this repo. To use it, run:

export GCCLOCALRC=/path/to/hpcpp/scripts/pm-localrc/localrc

Note: Please uncomment the following line in apps/fft/CMakeLists.txt if using nvc++ version < 23.7?

  # uncomment only if using nvc++ earlier than 23.7 to find libcublas
  # target_link_directories(${exec_name} PRIVATE /opt/nvidia/hpc_sdk/Linux_x86_64/23.1/math_libs/lib64)

Run Apps

cd hpcpp/build
srun -n 1 -N 1 -G <> -A <acct> -t 30 -C <cpu/gpu> ./apps/<appname>/<appname> [ARGS]

hpcpp's Issues

fix or reproduce stdexec errors

possible solutions:

  1. separate out CPU and GPU schedulers implementations into two cpp files
  2. reproduce the error with standalone cpp files (no dependencies) and share it with stdexec team.

Apps using `repeat_n` fail to build with `-stdpar=multicore`

hpcpp apps including both stencils fail to build when -stdpar=multicore (aka CMake -DSTDPAR=multicore). The build errors originate from the repeat_n.cuh file adapter from nvidia/stdexec.

Possible fixes:

  1. Quick (and temporary fix): Use compiler directives #if defined(USE_GPU) to disable code using repeat_n and provide alternative implementation
  2. Implement a repeat_n sender for CPU scheduler.

formatting

We need a formatting file for project files (cpp and hpp) and cmake files for CI and guideline purpose.

remove magic_enum

We aren't using magic_enum in our apps so far as it requires advanced compiler features not available in nvc++ yet. We can remove this and it's instances if any from CMake files too to avoid baggage.
