Description Arguments Examples
Launch a loaded kernel with provided arguments.
grid |
Three member list giving x, y, and z dimensions (in blocks) of grid. The list members do not need to be named, but must be in x, y, z order. |
block |
Three member list giving x, y, and z dimensions (in threads) of each block. The list members do not need to be named, but must be in x, y, z order. |
args |
List of numerics and XPtrs to device memory (as returned by h2dVector & h2dMatrix). Type and order of arguments must match kernel signature, and there is no checking that this is the case. Incorrect argument specification may either result in memory faults or, worse, silent but unforeseen behavior. |

cu <- new(Cuda)
# create data matrix and load on device
x <- cu$h2dMatrix(matrix(rnorm(20), nrow=5, ncol=4));
# create a matrix to hold results and load on device
y <- cu$h2dMatrix(matrix(0, nrow=5, ncol=4));
# load and launch kernel
k <- system.file("extdata", "stride.cu", package="cudalite")
cu$loadKernel(k)
cu$launchKernel(list(1,1,1), list(3,2,1), list(5, 4, x, y))
#retrieve results
res <- cu$d2hMatrix(y)
## End(Not run)
