Race Issues On multi-core systems

Has there been any testing of Q-Chem for race issues involving multi-core and GPU systems?

Q-Chem is tested routinely with parallel execution and on GPU systems. Are you observing incorrect behavior?

Not at this time. I was just curious since a number of other multi-core/ GPU apps have encountered this problem. Also, it is a random occurrence which is not easily detectable and can significantly affect results from the calculations performed.
