How to run on Cluster

first ssh

ssh [email protected]

Clone

git clone https://github.com/NH89/opencl-sph

Load Intel modules for compatibility

module load intel-opencl-sdk 

Create build and install folder, and navigate into that folder

mkdir mybuild
mkdir install
cd mybuild

Run Cmake with hint

cmake -DCMAKE_INSTALL_PREFIX=../install .. -DOpenCL_LIBRARY=/pawsey/opencl-sdk/7.0.0/opencl/SDK/lib64/libOpenCL.so

(Alternatively load cuda module)

cmake -DCMAKE_INSTALL_PREFIX=../install .. 

make targets

make
make install 

Reserve resources of GPU

srun -A gpuhack02 -N 1 -p gpuq --reservation=gpu-hackathon --gres=gpu:2 --pty /bin/bash

Run executable

./install/bin/opencl_sph

Sit back and drink a coffee

An implementation of smoothed particle hydrodynamics using OpenCL.

This code is under development and may be subject to heavy revision at any time.

The nearest-neighbour search (NNS) algorithm is derived from the method used for Fluids v3. by Rama Hoetzlein.

• Clone this repository

  git clone https://github.com/tauroid/opencl-sph

• Edit the first line of makefile to point to your MATLAB installation

• make

You will need OpenCL headers and libraries.

This has only been tested on linux, with gcc.

The current interface is through MATLAB - see go.m or go_fluid.m.

These implement an elastic solid based on Becker et al. 2009 and a simple pressure gradient fluid respectively.

Using particle configurations other than a cube at the moment requires manual specification in the position field of psdata.
