I wonder if that's a client

I wonder if that's a client program bug (i.e. the results are
complete nonsense, caused by an uninitialized variable or so)
or if it's a validator problem.

(I have a few of those "no consensus yet" things too)

YES!!!!!!!! Was about time the minority strikes back!!

Again, as has been said before: The devs are working on this issue. I guess after we'll see SSE optimized apps (hopefully soon ;-) ) mixed with non-optimized apps in the field, results will even become more "slightly unequal", so this issue is kind of important.

The inaccuracy of the SSE code means extra 0,1% difference in the results.

Is that small enough for current validators to cope with? Well, maybe the current cross-platform validation problem isn't related to floating point accuracy at all, but to other things? Different implementations of qsort come to mind, so that different permutations of items with equal "weight" may result when sorting candidates.

Well, if developers are

Well, if developers are looking for test data on the cross-platform validation problem, here's an interesting datapack

http://einsteinathome.org/host/777013/tasks

About half the WU run on Linux failed to validate against Windows :-(.

Usually this kind of validation problem happens less frequently (also the host produced better results with a different datapack in the past).

Wow. If my Mac was coming out on the short end that frequently, I'd be thinking about putting both cores on CPDN or Rosetta until they had solved the problem here at Einstein. As it is, I've only had one WU that failed to validate against Windows (ID #33893916).
