I have 4, on a Q9450 they are estimated to take 12-13 hours based on time so far and %. Otoh CEP2 wus on my one linux core, same box, always estimate to 12 hours and mostly they take 6-9 hrs, very rarely taking 11 or 12. Will see how they turn out in the morning.

Pretty amazing to sit on a water diet only for the duo and this morning 2 of them are at bottom. Suspended the RTS jobs, but those running, since they need only 2 resp. 33 more minutes and then away they are on their way. Assuming they live by the same 12 hour cut off rule, the TTC shows as 12:30:05 hours.
----------------------------------------The bandwidth issue has been discussed by knreed how that will be dealt with. No messages here though, given that the jobs ran generate enough continues traffic to allow BOINC to maintain the bwdown value above the 128mB warning level. (802.11N flies here) NixChix, presume you meant the Progress percent... whilst typing slow and checking things, the Elapsed time counting started immediate, and after about 4.5 minutes the CPU time counter started too combined with little % progress steps. Did notice that during the model setup the system got slow responsive, so think that I will allow the 2 to run concurrent for a little and observe impact... throttle set at 100%, and after maybe set the ThreadMaster GUI ** to allow 90, 80, 70% to see how impact manifests itself. Will monitor also with Process Explorer on the system uses, PFs Delta etc, how efficiency keeps up. Think with the forewarning by armstrdj, OPT-IN is when really choosing to run them. Process Explorer took 95 seconds to load, so know what you get into ... 12 minutes elapsed, 6 minutes CPU time, 0.892% progress for starters Lets crunch :D ** still the best science-app level CPU cycle permission *smooth* throttle controller to be had for BOINC on windows. The default is set to not allow more than 40% of system (80% of core) and that's what it's running at now. Switching up to 100% this moment to see how it impacts browsing and typing messages... update later.

PF Delta is sizable at 1.7MB and peaking even at 4.2MB, 15 minutes recorded as CPU time (of 27 minutes elapsed), with a chunk of kernel time. Will let Process Explorer continue and make a screen dump of the tasks properties when having run a couple of hours... armstrdj did warn us :D

It seems at 25% it takes 3 hours to complete.
----------------------------------------12hrs Windows VS 9hrs Linux - what a big difference ![]() ![]() |

Presume there to be a selection of heavy and less heavy to be put through there paces, so they'll hit the 12 hour cap mark too aswas beta tested on Linux!
----------------------------------------I've put the version in the title. Should there be a second round, all needs done is change that and all know which release we're discussing. Process Explorer is collecting interesting data. Don't think I'll be running 2 concurrent on this duo for very long, though they have now been for 15 minutes... it's noticeable at 100% TM throttle. edit: Definitely needs 4.5 minutes for the model grid to build before CPU time start counting... monitoring with BOINCTasks makes it so much easier.

To add to the 12 hours showing in TTC, from running many on Linux we know that the % progress is tuned to exactly 12 hours run time, not the real progress. Maybe armstrdj could revisit that bit so it takes number of jobs completed also into consideration. 15 of 16 jobs done after 4 hours does not make 12 hours to be very probable and highly impacts the client scheduler and buffering behavior (and a roller coaster DCF when mixing with other sciences).

Checkpointing:
----------------------------------------The first 2 checkpoints came very soon: after 0.4% and ~1%. For the 3rd checkpoint you have to wait 1½ to 2 hours. However there was a big difference between two tasks on the same machine (C2duo) of about 25 minutes. Thereafter the checkpoints seem to come more regular with shorter intervals. On a Quad running 4 beta's on all cores without other processes: A lot of CPU-time seems wasted. After 2 hours wallclock 1hr54min cpu-time. Perhaps due to heavy io-ing (10 billion in the first 2 hours) and millions of page faults. Rebooted 1 system after the 3rd checkpoint: Tasks restarted fine.

6 minutes is quite moderate or 3 minutes per hour aka 95% efficiency. Wish my quad Linux box could show that for CEP2, particular when using the system.
----------------------------------------edit: monitoring from remote with 2 running concurrent and 2 DDDT2 on the other cores, showing exactly 30 minutes difference after 5:46 hours wallclock on one job and the other 34 minutes after 5:15... 3 minutes per hour for the moment would be an improvement in my book... my centrino shows 17 minutes gap after the 2:14 hours wallclock, running at 100% throttle and system in use doing multiple things... Firefox ate 2:39 hours since it was last loaded yesterday morning.

Also getting the Beta - The Clean Energy Project - Phase 2 requires 128.00 kbps download bandwidth. Your computer has been measured at 95.29 kbps. I know for sure I have more than that. Is there a workaround? It's really annoying not to get WUs due to this limit? I know for sure I have more than that. BOINC 6.10.58 x64 |

Download a couple of HPF2 jobs... that will pump it up. Download speed is highly affected by many short files which really never get to reach max speed, so by forcing a few jobs to come that are known to have bigger downloads, BOINC will adjust, temporarily. Mine is measured 266kB presently off from a recent mix of C4CW and HPF2.
