Hi, I have a problem that I can not explain.
On the second iteration clEnqueueReadBuffer hangs the system and it goes to BSOD saying that infinite loop at video adapter detected.
Any suggestions what am I doing wrong?
Here is the outline of the algorithm:
1. Init all variables, queues, kernels, writing data to buffers and so on
//here's the basic cycle goes:
2. do{
2.1. Write buffer to "Nebalans" kernel
2.2. clEnqueueNDRangeKernel Nebalans
2.3. Read buffers from "Nebalans" kernel
2.4. clFinish(queue)
2.5. clEnqueueNDRangeKernel JacobiForm
2.7. Read buffers from "JacobiForm" kernel
2.8. clFinish(queue)
2.9. for (i = 1..N)
2.9.1. for (j = 0..i)
2.9.1.1. clCreateBuffer(-s)
2.9.1.2. clSetKernelArg (for kernel SAXPY_cond)
2.9.1.3. clEnqueueNDRangeKernel SAXPY_cond
2.9.1.4. Read data from kernel SAXPY_cond
2.9.1.5. clFinish
2.9.1.6. Release mem objects
}while (EndCondition())
code is here
