Question

Before dispatching a large multi-node training job on a newly repaired GPU node, an operator wants to run a comprehensive validation that stresses memory, executes compute tests, and checks integration health beyond a quick sanity check. Using the DCGM diagnostic tool (dcgmi diag), which run level should the operator select to perform this deeper, longer-running validation?

Accepted Answer

Run level 3 (-r 3), which includes extended memory and hardware stress tests taking several minutes

Answer

Run level 1 (-r 1), a quick sub-second sanity check of deployment and software configuration

Answer

Run level 4 (-r 4), which disables ECC to speed up throughput benchmarking

Answer

Run level 0 (-r 0), which only reports the current driver and firmware versions
