Common Pitfalls
1
Relying on disk-based data transfer can create bottlenecks in performance.
This occurs because disk access is slower than in-memory operations, leading to latency issues. To avoid this, utilize direct memory transfers between components whenever possible.
2
Using Python for cuGraph can introduce overhead and complexity.
Python's inherent overhead can slow down compute-intensive tasks. Instead, leveraging C++ for critical components can enhance performance significantly.
