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).

Yes, this is quite exceptional. Most of the time, all my Linux hosts including the one mentioned above are doing fine, only losing about 1 in 10..15 WUs due to validation problems.

There could be a light at the end of the tunnel.
In this WU the validator didn’t think that my windows result agreed with bprokopow’s Darwin result and we have both been waiting for a 3rd result to sort it out. A couple of days ago the validator decided that we did agree after all and granted the credit. Clearly there has been some tweaking to good effect.
The downside is that when Grant subsequently returned the 3rd result overdue he got nothing for 414,404 second work. :(

Hi!

This one's funny (the first one to be replicated to 4 PCs that I noticed):

http://einsteinathome.org/workunit/33712959

First computer to receive is running Win98, wingman is on XP, and they didn't agree.

Third one was a Mac, which seemed not to agree to either result.

Then the workunit got send to "RiversideCityCampus" which is best described as a Super massive Black Hole for workunits because workunits are sucked into this site and disapper forever :-)

Now my veteran Pentium III got the workunit, and it's running on Linux, the third OS involved. Hopefully it will validate against the Darwin Mac, or else the WU will reach "initial replication 5" and be sent to yet another host.

Come on little Workunit, hang in there!! You'll finally make it to the science database :-) :-)

That is a good one....

Gotta love the "RCC Black hole" ;-)

I'd put money down that your host and the OSX host validate and put this monstrosity of a WU to rest.

Here's another interesting one:

http://einsteinathome.org/workunit/33925402

The first two hosts are a P4 and an AMD Turion both running XP, surprisingly they didn't agree and the WU was sent to my C2Q running Linux. Not wanting to get involved in the battle of the validator, I aborted the WU.

The WU has now been sent to a PD also running XP....

Will the two Intel boxes validate, or will the WU be sent out to a 5th host...

All that should mean is that your two results ended up being weakly similar. I'd start worrying if a 3rd result gets assigned and returned and then there is still no consensus. There is obviously a chance though that the 3rd result comes in and is strongly similar with only one of you and the other result may not get credit. Without something explaining "why", those scenarious are the toughest to accept, but they could be legitimate. For example, your system may have had some sort of memory glitch or whatnot that fouled a math routine, so the result is truly non-similar.

I still believe that expansion of the "outcome" column and better explanation of invalid results is needed BOINC-wide...

Your result was compared with 1 from a MAC and it did not match:(

There are validation problems between diff. OS right now. But they are working
on fixing it.

YESSS! The WU finally validated (Darwin + Linux). I'm sorry for the Windows users.... ;-)

Yeah, those two Windows hosts combine for more than a weeks worth of of waisted CPU time, that's a lot of electricity!!!

At this point I'm starting to worry about the environmental impact of these validation problems, screw the credit... I hope Al Gore doesn't peruse this forum ;-)
