Greetings, I am working on writing some additional opencl kernels (potentially to incorporate in to viennacl) which involve column-wise reductions. A simple case would simply be the sum of each column of a matrix. However, I am having an extremely difficult time getting my kernel correct (reductions are tricky to me). That said, after searching for some resources I came across an old post on sourceforge referring to column-wise kernels ( http://sourceforge.net/p/viennacl/mailman/message/27542552/) with viennacl. This leads me to my primary question.
Are there such kernels already in ViennaCL that I have overlooked? If not, are there any examples or resources you would recommend to help learn this topic? I have tried searching further but the only thing I can really find is a reduction of an entire matrix (which is relatively simple) as opposed to by column or row. Best regards, Charles
