Hi, I'm new to Intel Iris graphics 5100 and Intel tool set, if my question is duplicated, please point me to original ones ;-)
Q1, how to generate kernel statistics? Code-Builder exposes II and ASM, but I haven't found stats, such as # of full ALU/half ALU, Nops, global/local st, etc. This would be helpful in my kernel tuning. I would assume Intel exposes it, since the ASM are exposed.
Q2, I set gws and kernel argument in Kernel Builder, to perform "analyze" (or "deep analyze"). But Kernel Builder crashed with error msg: "Exception sending message to server: read: An existing connection was forcibly closed by the remote host". Any one met this before?
(If it is a real bug, is there a place to file it?)
I'm running Windows 7 64bit SP1, bootcamped on Mac Mini (version, late 2014, i5-4278U, Iris 5100). With (presumably) latest Intel Graphics and OpenCL driver, tools, VS2012. The kernel is not complicated, it is pretty much a unrolled 6x6 Gaussian filter. Input and output are 512x512 floating point buffer objects.
Thanks much for any suggestions.
