Hi everybody. I’m experimenting with OpenCL and I faced the following problem: inside my code I have a function that is performed on the GPU using OpenCL. Every time the function is called I perform the whole OpenCL environment setup with the context and command queue creation, the program build and so on. Right now I don’t care about performance, I know it is very slow. The problem is that after 15 calls to the function I cannot create a new context. The error number is -6, CL_OUT_OF_HOST_MEMORY but I don’t see any problem with the local host memory, I’m not working with big data sets.
At the end of the function I release the context and in theory I would not face any problem. The GPU I’m using is the Nvidia GTX480, and curiously the number of Streaming Multiprocessor is 15 as the number of function I context I can create before the memory error. Can anybody explain me this behavior? Thanks
