laplace_gpu

===========

Laplace solver running on GPU using [CUDA], with CPU version for comparison. In addition, the CPU version contains support for [OpenMP] and [OpenACC].

[CUDA]: http://www.nvidia.com/object/cuda_home_new.html

[OpenMP]: http://openmp.org/wp/

[OpenACC]: http://www.openacc-standard.org/

Usage

-----

Change the problem size by modifying `NUM` in `laplace_cpu.c` and `laplace_gpu.cu`. To make all the executables (CPU, OpenMP, OpenACC, and GPU) type `make`. 

To run each version, simply type

	$ ./laplace_cpu

	$ ./laplace_gpu

	$ ./laplace_omp

	$ ./laplace_acc

Requirements

------------

The makefile is set up to use `gcc` to compile the CPU version, `nvcc` (part of [CUDA]) to make the GPU version, and 'pgcc' (part of the [Portland Group]'s Accelerator compilers) to make the OpenMP and OpenACC versions. `gcc` may also be used to make the OpenMP version by changing the appropriate line in the makefile.
