```cpp
class CDistributionSpecRandom : public CDistributionSpec
{
public:
enum EDistributionLevel
{
EdlSegment, // Cross-segment distribution
EdlWorker // Intra-segment distribution to worker threads
};
// New members
EDistributionLevel m_edl; // Distribution level
ULONG m_ulWorkers; // Number of workers
CDistributionSpec *m_pdsSegmentBase; // Base segment distribution
};
```
expand CDistributionSpecRandom.
