Hi Matt, thanks again for your interest and feedback :-) Philippe mostly answered your external BLAS-related questions, We may, if at all, provide only a few partial BLAS hooks, but instead squeeze out more performance from fusing multiple BLAS calls into a single kernel.
From my standpoint, what I expect to be addressed in the ViennaCL 1.6.0 release is, vaguely in order of priority: * Full integration of the micro-scheduler and the generator * Fully HTML-based Doxygen documentation * Support for reductions * Get rid of Boost as much as possible/reasonable * Stabilize existing (experimental or OpenCL-only) functionality I'm hoping for a full release towards July, with features incrementally showing up in the developer repository as usual. We will then also see how it goes with respect to the generator vs. external BLAS libraries and whether this makes actual sense for users. For GPUs there's probably little value because the generator is already pretty fast, yet I see some potential in scenarios for the CPU backend, whenever there's no OpenCL SDK available.
