   I have a possible explanation.  When cudnnFind measures the runtime of algos that have similar runtimes, the selection of which is fastest may differ from run to run.  Filtering the algorithms based on MXNET_ENFORCE_DETERMINISM=1 just throws out the non-deterministic algos.  However, the results from run to run may differ based on the non-deterministic choice of which deterministic algo to run.
