1) Message boards : Number crunching : Is It Normal For MW To Use All 8 Cores For 1 Work Unit? (Message 52622) Posted 23 Jan 2012 by Ex_Brit Post: OK thanks.
2) Message boards : Number crunching : Is It Normal For MW To Use All 8 Cores For 1 Work Unit? (Message 52618) Posted 23 Jan 2012 by Ex_Brit Post: Just a query really not a complaint. I just happened to be looking at the BOINC Manager when I noticed 4 work units complete in literally a flash - they were using all 8 cores. I've never seen that before.

5) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 49183) Posted 8 Jun 2011 by Ex_Brit Post: Once again >50% of work units are failing due to computation error so am turning off work fetch for Milkyway until such time some kind of attention is paid to this ongoing problem.
6) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 49125) Posted 30 May 2011 by Ex_Brit Post: It just happened again and same pattern as the previous pair of WU's. One completed and one failed 'Computation Error'. Who is writing these things?
7) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 49095) Posted 29 May 2011 by Ex_Brit Post: My latest WU's seem to be better behaved with the last one completing without incident and I have 2 more on the go as we speak.

9) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 49074) Posted 27 May 2011 by Ex_Brit Post: I see now that it's vanished from the work unit progress page here, why do they delete them so quickly? It serves no purpose except perhaps drive us insane. I now have subsequent units in progress, so far so good, and those are all that now show there. So unless you caught the above post yesterday and took a look I'm afraid you are out of luck.

(Message 49058) Posted 26 May 2011 by Ex_Brit Post: Computation failed. the weird thing is that the log doesn't say that, it says merely that it finished.

11) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 49041) Posted 26 May 2011 by Ex_Brit Post: OK I've turned on work fetch again but there are no WU's to download a.t.m. They take while, almost to the completion stage in some cases then suddenly the status changes to 'Computation failed' & progress zips to 100% and all I can do is update to get rid of them..
12) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 49038) Posted 26 May 2011 by Ex_Brit Post: My problem is with the regular WU's not the GPU ones. I don't use my GPU as previously stated, overheating issues and it caused problems with other applications. What get's me is the issue hasn't even been mentioned in the News and it's been going on for ages. They also need to alter this website interface so that more WU's are kept on view. At present they disappear within hours so no one can check what past WU's were that gave the issue without a lot of delving.

(Message 49033) Posted 26 May 2011 by Ex_Brit Post: but you can always use the ones provided by the server. Are you saying it's fixed or what? I wasn't aware we can pick and choose where our work comes from.
14) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 49007) Posted 25 May 2011 by Ex_Brit Post: I understand, however since I had overheating issues I don't allow any projects to use the GPU any more. I also am not interested in using beta graphics drivers just to suit a project. This project needs to fix the work view problem too, there is no reason why recent work units should vanish from the records so quickly. This problem started with THIS thread so isn't anything new.
15) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 48953) Posted 24 May 2011 by Ex_Brit Post: I have no idea what the difference is, sorry. All I know is I keep getting work units that fail "computation error" and I'm not getting that with any other projects.
16) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 48913) Posted 21 May 2011 by Ex_Brit Post: The computation error idiocy continues. I'm about to withdraw my meagre support for this project.
17) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 48834) Posted 17 May 2011 by Ex_Brit Post: So you reckon it's safe to turn on work fetching? For me the answer is that I never turned work fetch off. I did try to catch the de_separation_17_3s_fix_5 WUs and abort them when they appeared so that they wouldn't put a GPU out of commission for hours. I think the project should institute a policy that no new WU runs be created until after at least the 2nd cup of coffee :) Well for now it seems the supply has dried up anyway. When they failed what got me were the dozens of errors Boinc/Windows threw up. Fine if one was sitting in front of the machine when they occurred but a bit off-putting when one had been away from the machine for a few hours.
18) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 48832) Posted 17 May 2011 by Ex_Brit Post: Mercifully the malformed WUs seem to have mostly burned their way through the system. Haven't seen any of the really bad de_separation_17_3s_fix_5 WUs for a couple of days. Had one de_separation_10_3s_free_2 WU yesterday and 1 so far today. The latter aren't as troublesome because they didn't have a tendency to get stuck and run for hours like the de_separation_17_3s_fix_5 WUs. Hopefully in the future the admins will cancel malformed WUs and not let them simply run through the system creating havoc. Please? So you reckon it's safe to turn on work fetching?
19) Message boards : Number crunching : Is Anyone Addressing This Constant Computation Error Problem? (Message 48830) Posted 17 May 2011 by Ex_Brit Post: Is anyone addressing the WU's that constantly fail due to computation error?....see the Bad WU thread also - no one seems to be at home in that thread lately. At least so we know when it's safe to resume work fetching. The reason I ask is that I see no mention of it in the News.
20) Message boards : Number crunching : Bad WUs (Message 48786) Posted 15 May 2011 by Ex_Brit Post: This is ridiculous...now de_nbody_orphan_test_2model_4_50204_1305471400_1 failed and one before that. I've aborted another one since and am turning off the work fetch until someone sorts this mess out.

Next 20
