Created this PR to fix test_sharded_grad_scaler_found_inf failing test in Jira ticket https://ontrack-internal.amd.com/browse/SWDEV-479939.
The test was failing for Navi arch, that too when the test runs with cpu_offload=true. The cpu_offload=true, results in running the grad scalar optimizer to run on CPU. The grad scalar optimizer uses vectorized & scalar operations to find inf values in tensors. It seems for Navi arch, the vectorized operation is running unreliably, perhaps taking longer time to execute and resulting in failure. Adding a sleep statement in the vectorized operation helps run it successfully.
