Learn R Programming

⚠️There's a newer version (1.1) of this package.Take me there.

gputools (version 0.24)

A few GPU enabled functions

Description

This package provides R interfaces to a handful of common statistical algorithms. These algorithms are implemented in parallel using a mixture of Nvidia's CUDA langauge, Nvidia's CUBLAS library, and EMI Photonics' CULA libraries. On a computer equiped with an Nvidia GPU some of these functions may be substantially more efficient than native R routines. Thanks to Craig Stark at UC Irvine for donating time on his lab's Mac hardware.
