Detect the configuration of OpenCL platforms

This code detects the configuration of the OpenCL platforms available on the machine and outputs it to a file.

It can be used as a quick check whether OpenCL is working.

#include <iostream>

#if USE_OCL == 1

#include "sgpp/base/opencl/OCLManagerMultiPlatform.hpp"
#include "sgpp/base/opencl/OCLOperationConfiguration.hpp"

int main(int argc, char** argv) {
  std::shared_ptr<sgpp::base::OCLOperationConfiguration> configuration =
      std::make_shared<sgpp::base::OCLOperationConfiguration>(
          "detectPlatform.cfg");
  (*configuration).replaceIDAttr("VERBOSE", true);

  sgpp::base::OCLManagerMultiPlatform manager(configuration);

  configuration->serialize("detectPlatformOut.cfg");

  return 0;
}
#else
int main(int argc, char** argv) {
  std::cout << "no OpenCL support" << std::endl;
}
#endif
