Transcript
GPU Programming in Metal • Twitter: @alienxp03 • Not a
GPU programmer
Metal • Introduced in iOS 8 • Only for iOS
devices • Usage - Graphic rendering - Parallel data computation
Basic guide • Initialise Metal
Basic guide • Call the compiled shader function
Basic guide • Set parameters
Basic guide • Threadgroups
Basic guide • Run the computation • Get the result
Shader language • Using C++11 with some extension and limitation
pow(x, y) • 12,228 integers - CPU : 0.028833416668931 secs
- GPU : 0.0302730000112206 secs
pow(x, y) • 33,554,432 integers (2 ^ 25 ) -
CPU : 73.7681545416708 secs - GPU : 38.1098593333445 secs
Implementation • Didn’t compare precise::pow vs fast::pow • Initialise the
array on CPU, then pass it to GPU for computation • Using CPU cache memory
None
iOS 9 • Metal is now available on OS X
too • MTLResourceOptions
iOS 9 • Instrument, Metal System Trace
None
Lesson learned • We have GPU too, and it’s pretty
powerful • And it’s idle almost the whole time
Real world application • For data simulation or visualisation •
Though the truth is, I have no idea • Just did it for fun
