• Description: Iterates over all tensors in scaledGrads to check for Inf or NaN. Sets foundInf to 1.0 if any Inf or NaN is detected; otherwise, foundInf remains unchanged. Then unscales all tensors in scaledGrads by multiplying with invScale.

• Formula:

  $$foundInf = \begin{cases}1.0, & if any Inf or NaN exists in scaledGrads,\\ foundInf, & otherwise. \end{cases}$$ $$scaledGrads_i = {scaledGrads}_{i}*{invScale}.$$

Each operator has calls. First, aclnnForeachNonFiniteCheckAndUnscaleGetWorkspaceSize is called to obtain the input parameters and compute the required workspace size based on the process. Then, aclnnForeachNonFiniteCheckAndUnscale is called to perform computation.
