//2. Query the host for OpenCL devices

//3. Create a context and a queue to associate the OpenCL devices.
ksack->createContextQueue(i, &logfile);
//4. Create programs that will run on one or more associated devices.
ksack->createProgramBuild(i, &logfile);
//5. Create memory objects on the host or on the device.
//6. Copy memory data to the device as needed. Create memory objects on the host or on the device.
ksack->createMemObjects(&logfile);
//7. Create Kernels
ksack->createKernel();
//8. Provide arguments for the kernels.
// ksack.createKernel();
//9. Submit the kernels to the command queue for execution.
//10. Copy the results from the device to the host
//ksack.executeMemObjects();
ksack->executeComputation(i, &logfile, local_threads[k]);
ksack->printResults(&logfile);
