List of SMP WUs with the "1 core usage" issue

martiou · Post by **martiou** » Tue Sep 08, 2009 12:43 pm

I received several WUs which crashed immediately after startup ("CoreStatus = FF (255)").

With core 2.07 :
- 20/08 :
.Project: 2669 (Run 9, Clone 20, Gen 198) - compressed_data_size=1518487
- 26/08 :
.Project: 2677 (Run 11, Clone 88, Gen 31) - compressed_data_size=1490678
- 02/09 :
.Project: 2677 (Run 3, Clone 20, Gen 41) - compressed_data_size=1503302

With core 2.10 :
- 06/09 :
.Project: 2677 (Run 30, Clone 77, Gen 33) - compressed_data_size=1495164
- today :
.Project: 2677 (Run 12, Clone 88, Gen 38) - compressed_data_size=1508891
.Project: 2677 (Run 24, Clone 57, Gen 32) - compressed_data_size=1498655

2671, 10, 3, 86
2671, 12, 40, 89
2671, 32, 41, 88
2671, 37, 79, 78
2671, 49, 98, 84
2671, 50, 97, 91
2671, 52, 43, 82
2677, 1, 30, 31
2677, 30, 77, 33

each has had the following in the FAHlog

Some units have been issued more than once so is there any chance that we can get them deleted from the queue.

Ditto

,
after reading this 1st... I find no use in looking up the Specific WU info

.

Just curious, as I was out of folding for the Holiday weekend, if any advances as to the Crux of the problem have been made?

An update would be helpful

. None of mine will make it either when a WU is over 1 hour per %

. It is a lot of wasted electricity and Hardware stress for nothing with these slow WU's.

Please advise, as I think that only one or 2 WU's finished over the weekend on 4 VM's running.

Do we still have to report bad WU's?
Apparently nobody cares to delete them, they keep reappearing

This got loaded on my Mac Mini 1.83 GHz C2D running Leopard 10.5.8. It seemed to not want to get started, but looking at it, something weird was happening when it tried to run. It might be one of the runs only with one FAH_Core process as my CPU meter showed 50% of one core and ~5% of the other core busy. I had recently received the V2.10 FAHCore_A2, and I tried again after deleting the V2.10 and letting it download the V2.11 core:

and so we're processing normally now. I notice that there is another WU that terminated after I ran through my P2669:R13:C71:G168. Work Unit for Project: 2677 (Run 19, Clone 97, Gen 30) also exited with the Core Status = FF.

I searched this Forum but didn't see either of these Work Units reported.

Project: 2669 (Run 2, Clone 6, Gen 133) got it 4
times before it deleted and went to
2677 (Run 30, Clone 77, Gen 33) right after, (3 times) before finally got a good one

Can kasson or someone from Pande please comment. "Bad" WU's are being reported. Why can they not be removed from the servers?

Post by **VijayPande** » Thu Sep 10, 2009 9:25 pm

We're looking into what's going on here. We could try to do "whack a mole" on bad WU's as people report them, but it's better for us to get to the root of the issue, especially since others are likely having trouble and not reporting. The server will eventually abandon WUs that are bad, but it takes more than one computer to make the report to ensure that it is indeed bad. Being too liberal here with banning WUs leads to both no science done and WU shortages. I or Kasson will give an update hopefully in a day or two if we have some news. Sorry this is taking so long.

Vijay,

Thank you very much for responding. You're right, this is taking too long to sort out.

Firstly, with regard to bad WU's, you do not need to be a programmer to spot these a mile away by the size of the WU. We're not asking you to "whack a mole", just remove the obviously bad units from the server. This, along with making sure that no undersize bad units are generated, or added to the server in the future is the fix I would suggest you should be applying. Issuing the Core_a2 v2.10, to detect these units on the client side and error out with a 'FF' status is not fixing the issue. It's still a complete waste of resources for a single client to repeatedly download a bad unit 3 or 4 times before moving onto the next. It wouldn't be so bad if the client actually communicated the "it will only ever run 1 core" badness of the unit to the server so it is never issued again either to the reporting client or another for that matter. This may be an improvement on the previous v2.08 core behaviour of these bad units (ie. running on a single core) were it not for the fact that the client seems to be hanging for some people while locally deleting the bad unit. Not to mention that it is pretty obvious by now that v2.10 has issues when running less than 4 cores. I'd even suggest that by the v2.10 client still being in the wild and not having reverted to the v2.08 client until a better solution can be found, is a mistake, judging from the number of people running 2 cores in VM. I hope these issues are resolved quickly. The v2.10 client pretty much ensures less science is being done.
