WebWhen I tried this example on my MacBook Pro (15" 2014) using Iris Pro GPU the program is reporting "Test failed" for every test run. Which means that the result of the OpenCL FFT is different from the result of the Accelerate FFT. If I run the same test on my iMac 27" which has an GeForce GTX 680MX GPU all test runs are passing successfully. WebFabien Dournac's Website - Coding
