As explained in Different cores setting have different results - #2 by jeff.dietiker
“It is possible you will get different particle position over time due to the difference in order of operation.”
Since the totals match, and the other numbers are fairly close, I think that this does not indicate a problem, just normal variation.
The core dump on the other hand indicates that something has gone wrong. Can you copy/paste the last part of the output from the console, including the whole stack trace (not just a screenshot?) Thanks.
