Random number generation?

[jeremysalwen]

In this thread http://sourceforge.net/p/viennacl/discussion/1143678/thread/f6fe1301/ it seems that there is no functionality for generating vectors/matrices of random numbers. Is there any suggested workaround for generating random numbers on the opencl device?

I am finding that copying the random numbers over is taking an excessive amount of time (I am generating a 784*784 matrix of booleans in my inner loop).

Hello Jeremy,

It is not supported by ViennaCL right now. You may want to use an external
OpenCL RNG library (such as
http://cas.ee.ic.ac.uk/people/dt10/research/rngs-gpu-mwc64x.html) and
create a custom kernel.
