Recently I've been implementing a Bellman-Ford-like algorithm, and there is a recurring need for accessing arbitrary indices on a DBM. As an example, for a `N`-sized square matrix `M`, a part of the a…

By optimizing, I mean

vex::vector a(ctx, 32);
SUM(popcount(a)); // it will be calculated as sum of popcount(long8). Or this optimization doesn't help much at all.

As per the documentation provided in VexCl, there is a SpMV function and it leverages Eigen's sparse matrix structure. In the same vein, would it be possible to have a defined API for interfacing with…

I want to launch a kernel many times "to test average run time for example, or change some arguments per call"
```
kernel.push_arg(a(0));
kernel.push_arg(b(0));
kernel.push_arg(c(0));
kernel.config( …

Focus on the topic. I'm a mac user wi…

I wrote a pretty toy spmv code. It hangs when trying to access the y1 (in device). If I append one empty row (so num_row == num_col), it runs smoothly.
Is it possible to support num_row < num_col as …
