Hi Charles, > One followup question, what distinguishes handle(), handle1(), and > handle2()? Do they refer to different buffers?
.handle() is the only one you need for vectors and dense matrices. Sparse matrices are represented by multiple arrays, hence the different handleX() routines (with numbers X) Best regards, Karli > On Fri, Aug 12, 2016 at 3:13 PM, Karl Rupp <r...@iue.tuwien.ac.at > <mailto:r...@iue.tuwien.ac.at>> wrote: > > Hi Charles, > > call .handle()/.handle1()/.handle2() to get the abstract memory > buffers, and call .opencl_handle() on them to get the cl_mem handles: > > A.handle().opencl_handle() > > Similarly, the command queue is obtained with > viennacl::ocl::get_queue().handle().get() > > Unfortunately it's not explicitly written in the manual :-/ > > Best regards, > Karli > > > On 08/12/2016 09:39 PM, Charles Determan wrote: > > I also would need to access the command queue handle > (cl_command_queue) > object to pass to clBLAS and clMAGMA functions.
