Dear Developers,
First, thanks for this promising package. I am wondering about an error
runnning the example script:
library("gpuR")
ORDER = 7024 # note that I increased the size to match my typical working data
A = matrix(rnorm(ORDER^2), nrow=ORDER)
B = matrix(rnorm(ORDER^2), nrow=ORDER)
gpuA = gpuMatrix(A, type="double")
gpuB = gpuMatrix(B, type="double")
gpuC = gpuA %*% gpuB
then the error happened:
ViennaCL: FATAL ERROR: Kernel start failed for 'assign_cpu'.
ViennaCL: Smaller work sizes could not solve the problem.
Error in cpp_gpuMatrix_gemm(A@address, B@address, C@address, 8L) :
ViennaCL: FATAL ERROR: CL_MEM_OBJECT_ALLOCATION_FAILURE
ViennaCL could not allocate memory on the device. Most likely the device
simply ran out of memory.
If you think that this is a bug in ViennaCL, please report it at
[email protected] and supply at least the following
information:
* Operating System
* Which OpenCL implementation (AMD, NVIDIA, etc.)
* ViennaCL version
Many thanks in advance!

Finally, I am wondering if exist some documentation that decribe a method for
implement a function and apply it row wise in a large matrix.
Many thanks in advance.
