oclContext | R Documentation |
OpenCL contexts host kernels and buffers for the device they are hosted on.
They also have an attached command queue, which allows out-of-order execution
of all operations. Once you have a context, you can create a kernel in the
context with oclSimpleKernel
.
oclContext(device = "default", precision = c("best", "single", "double"))
device |
Device object as obtained from |
precision |
Default precision of the context. This is the precision that
will be chosen by default for |
