Run the VSS Blueprint on your Spark
| Symptom | Cause | Fix |
|---|---|---|
| Container fails to start with "pull access denied" | Missing or incorrect nvcr.io credentials | Re-run docker login nvcr.io with valid credentials |
| Network creation fails | Existing network with same name | Run docker network rm vss-shared-network then recreate |
| Services fail to communicate | Incorrect environment variables | Verify IS_SBSA=1 IS_AARCH64=1 are set correctly |
| Web interfaces not accessible | Services still starting or port conflicts | Wait 2-3 minutes, check docker ps for container status |
NOTE
DGX Spark uses a Unified Memory Architecture (UMA), which enables dynamic memory sharing between the GPU and CPU. With many applications still updating to take advantage of UMA, you may encounter memory issues even when within the memory capacity of DGX Spark. If that happens, manually flush the buffer cache with:
sudo sh -c 'sync; echo 3 > /proc/sys/vm/drop_caches'
