ECC, Row Remapping and Memory Errors

ECC and row remapping detect or manage some GPU memory faults. Recovery depends on error containment, remapping state and the device’s supported procedure.

PRACTICE THIS IN REAL QUESTIONS

GPU Fleet Reliability & ObservabilityOne GPU's correctable memory error rate has been climbing for a week. What does that predict and what do you do about it?→GPU & Accelerator ArchitectureWhat does ECC on a GPU cost you, and why do you keep it on across a fleet?→GPU Fleet Reliability & ObservabilityWrite the policy for when a GPU is replaced rather than returned to service. What are the triggers and what do they cost?→GPU Fleet Reliability & ObservabilityWhat is an XID error, which ones mean the hardware is bad, and which ones mean somebody's kernel has a bug?→GPU Fleet Reliability & ObservabilityWith DCGM available on every node, what do you actually collect, what do you alert on, and what do you deliberately ignore?→GPU Fleet Reliability & ObservabilityHow do GPUs actually fail at fleet scale, how often, and which failures should the platform expect to handle every day?→
