hello !
I have an issue with an OpenCL application that compute matrix multiplication.
In particular i think that the problem is related to "clGetEventProfilingInfo" function. If i execute the program by using the CPU (Intel Core i5-4300U) all works fine and by using "clGetEventProfiling" function it calculates the execution time correctly.
Instead, if i use GPU (Intel HD4400), all works fine if i don't use the "clGetEventProfilingInfo".When i use "clGetEventProfilingInfo" to calculate the execution time and set a local work size in "clEnqueueNDRangeKernel" the program crashes and i don't understand why (instead, if i use "NULL" for local work size parameter in "clEnqueueNDRangeKernel" all seems to work) .Using Visual Studio debugger i think it's a "access violation" problem but i'm not shure.
This is the code of application : https://www.friendpaste.com/2NIpYvk8R96S01kFD3H3Gl
Can someone help me?
