Hi,
I am trying to create some elementary wrappers for VCL in javacpp.
Everything goes fine, except i really would rather not use those "cpu"
types (std::map,
std::vector) and rather initialize matrices directly by feeding row-major
or CCS formats.
I see that matrix () constructor accepts this form of initialization; but
it really states that
it does "wrapping" for the device memory.
Now, i can create a host matrix() using host memory and row-major packing.
This works ok it seems.
However, these are still host instances. Can i copy host instances to
instances on opencl context?
That might be one way bypassing unnecessary (in my case) complexities of
working with std::vector and std::map classes from java side.
But it looks like there's no copy() variation that would accept a
matrix-on-host and matrix-on-opencl arguments (or rather, it of course
declares those to be ambiguous since two methods fit).
For compressed_matrix, there seems to be a set() method, but i guess this
also requires CCS arrays in the device memory if I use it. Same question,
is there a way to send-and-wrap CCS arrays to an opencl device instance of
compressed matrix without using std::map?
Thank you very much for any sugestions.
