示例1: getGpu
//-----------------------------------------------------------------------------
GpuPtr Helper::getGpu(int index)
{
// Check it against selection criteria.
pair_int gpuBlock = selectDeviceAndBlock(index);
if (-1 == gpuBlock.first) return GpuPtr();
scoped_lock lock(mutex);
// First check to see if this GPU device has been initialized.
DevicePtr device;
DevicelPtrMap::iterator dit = devPtrMap.find(gpuBlock.first);
if (dit == devPtrMap.end())
{
device.reset(new Device(gpuBlock.first));
// Double check to make sure our device is OK
if (-1 == device->ID()) return GpuPtr();
devPtrMap.insert(std::make_pair(gpuBlock.first, device));
}
else
{
device = dit->second;
// Make sure we activate this per-thread.
device->setDevice();
}
// Now that we have a device, get the block implementation handle.
