In addition, the CPU version contains support for [OpenMP] and [OpenACC].\n\n[CUDA]: http://www.nvidia.com/object/cuda_home_new.html\n[OpenMP]: http://openmp.org/wp/\n[OpenACC]: http://www.openacc-standard.org/\n\nUsage\n-----\n\nChange 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`. \n\nTo run each version, simply type\n\n\t$ ./laplace_cpu\n\t$ ./laplace_gpu\n\t$ ./laplace_omp\n\t$ ./laplace_acc\n\nRequirements\n------------\n\nThe 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.\n\n[CUDA]: http://www.nvidia.com/object/cuda_home_new.html\n[Portland Group]: http://www.pgroup.com\n\nMisc\n-------\n\nThe most up-to-date version of `laplace_gpu` can be found at the [GitHub repository](https://github.com/kyleniemeyer/laplace_gpu) on GitHub.\n\nLicense\n-------\n\n`laplace_gpu` is released under the modified BSD license, see LICENSE for details.\n\nAuthor\n------\n\nCreated by [Kyle Niemeyer](http://kyleniemeyer.com).
