high performance computing on graphics processing units: hgpu.org

Here we present the revised and newly rewritten version of our earlier published CAVE package [J. Busa et al., Comput. Phys. Commun. 181 (2010) 2116] which was originally written in FORTRAN. The package has been rewritten in C language, the algorithm has been parallelized and implemented using OpenCL. This makes the program convenient to run on platforms with Graphical Processing Units (GPUs). Improvements include also some modifications/optimizations of the original algorithm. A considerable improvement in the performance of the code has been achieved. A new tool called input structure has been added which helps the user to make the data input and conversion more easier and universal.
