createDeviceBuffer method

DeviceBuffer createDeviceBuffer(
  1. StorageMode storageMode,
  2. int sizeInBytes
)

Allocates a new region of GPU-resident memory.

The storageMode must be either StorageMode.hostVisible or StorageMode.devicePrivate, otherwise an exception will be thrown.

Throws an exception if the DeviceBuffer creation failed.

Implementation

DeviceBuffer createDeviceBuffer(StorageMode storageMode, int sizeInBytes) {
  if (storageMode == StorageMode.deviceTransient) {
    throw Exception(
      'DeviceBuffers cannot be set to StorageMode.deviceTransient',
    );
  }
  DeviceBuffer result = DeviceBuffer._initialize(
    this,
    storageMode,
    sizeInBytes,
  );
  if (!result.isValid) {
    throw Exception('DeviceBuffer creation failed');
  }
  return result;
}
