> Does the Panama API give us any insight into the underlying capabilities of the CPU? Not just which versions/widths of SIMD instructions are supported (in a general cross-platform sort of way I guess), but also how much "true" concurrency of these SIMD instructions is supported? Unfortunately, no. We get the preferred species size and number of lanes. But everything that does not work on hardware is emulated in damn slow interpreted code. -- This is an automated message from the Apache Git Service.
