Detailed Description

The control class lets you control the parameters of a specific Bolt algorithm call, such as the command-queue where GPU kernels run, debug information, load-balancing with the host, and more. Each Bolt Algorithm call accepts the control class as an optional first argument. Additionally, Bolt contains a global default control structure that is used in cases where the control argument is not specified; also, developers can modify this structure. Some examples:

cl::CommandQueue myCommandQueue = ...
bolt::cl::control myControl;
myControl.commandQueue(myCommandQueue);
int sum = bolt::cl::reduce(myControl, ...);

Developers also can inialize and save control structures to avoid the cost of copying the default on each function call. An example:

class MyClass {
  MyClass(...) {
     cl::CommandQueue myCommandQueue = ...
     _boltControl.commandQueue(myCommandQueue);
  };
  void runIt()
  {
    int sum = bolt::cl::reduce(_boltControl, ...);
  };
  private:
       bolt::cl::control _boltControl;
  }

Sometimes, it can be useful to set the global default control structure used by Bolt algorithms calls that do not explicitly specify a control parameter as the first argument. For example, the application initialization routine can examine all the available GPU devices and select the one to be used for all subsequent Bolt calls. This can be done by writing the global default control structure, i.e.:

cl::CommandQueue myCommandQueue = ...
bolt::cl::control::getDefault().commandQueue(myCommandQueue);
bolt::cl::control::getDefault().debug(bolt::cl::control::debug:SaveCompilerTemps);
...
