gpuLm
(Package: gputools) :
Fitting Linear Models using a GPU--enabled QR
Most of this documentation is copied from R's documentation for lm. gpuLm is used to fit linear models using a GPU enabled QR decomposition. It can be used to carry out regression, single stratum analysis of variance and analysis of covariance (although aov may provide a more convenient interface for these).
● Data Source:
CranContrib
● Keywords: regression
● Alias: gpuLm

getGpuId
(Package: gputools) :
Discover the Id of the current GPU device
Queries the CUDA driver for the GPU device currently assigned to this thread. This is the id of the device that will be used for computation. If you wish to use a different device, use the chooseGpu function.
