package org.apfloat.aparapi
Transforms for using a GPU via the aparapi library.

This package contains Number-Theoretic Transform implementations that can use the GPU (Graphics Processing Unit) for executing the transforms. There is significant overhead in invoking the GPU, e.g. in transferring the data between the main memory and the GPU memory, so for small data sets there is usually no performance improvement, and in many cases performance can be even significantly slower. However for very large calculations, e.g. one billion digits, using the GPU can improve the performance noticeably, depending on the hardware used.
