Important!
So you’re wondering about Vulkan API support for progrmaming parallel compute code? Well, yes, indeed Vulkan can be used to program parallel compute code. But, it goes further than that. Matter of fact, OpenCL’s long-term plans are to be merged into Vulkan. So, if you want to program for the future, then try programming your GPGPU compute code against Vulkan API today. But, no worries. If your GPGPU code is small, simple, and easy to write, then it is also correspondingly simple to rewrite too. Not to mention, it appears that OpenCL will still be around for a long while, and maybe Vulkan API may have direct backwards compatible support for OpenCL too, eventually.
