1) Message boards : Number crunching : WU Time estimates (Message 98392) Posted 31 Jul 2020 by neil.hunter14 Post: Hi, I have a query about the estimated time that my WU should be taking. On download, BOINC Manager states the WUs should last around 8 hours (Rosetta 4.20 - JHR_bd4 and bd5 models) However, they have now been running for 13h 40m and still have over 11hrs to go. I'm now concerned they won't achieve the reporting deadline? I've noticed this before. How/why is the initial calculation so far out? Regards, Neil.

Both have the same problem for me, in that they get to around 98% complete, then seem to just hang there. Completion does not take place and I have aborted all 1.40 WUs on both PCs for now. Neil, UK. [/quote] ......they all seem to finally stick with 9m 53s to the end of the WU.

It has been running for 8hrs,20min and is at 98.050% my run time is 6hrs i haven't had this big a margin to finish before. Could it be the new mini app 1.40 or the task? 1hzh_2fiw_fchbonds_20_30sarel_SAVE_ALL_OUT_4704_76 http://boinc.bakerlab.org/rosetta/workunit.php?wuid=188078859 I'll let it run to end. pete.

First couple ran OK, but my third one seems to be stuck at 95% with just 10m 06s to go. The CPU Time is still running, and the BOINC Manager functions normally, but the WU is not getting any closer to 100% and completing. Neil ____________

6) Message boards : Number crunching : cpu optimization (Message 53475) Posted 31 May 2008 by neil.hunter14 Post: is that enough advanced notice for the progrgammers to have an optimized Rosie app ready ?! I've just hopped onto this thread, and flicked through it quickly. Seems like there's a catch-22 going on. Developers won't spend huge amounts of time optimising Code for the latest CPUs if there are many takers. But there won't be many takers until the Code yields significant performance benefits. My personal view is that Project Developers (not just R@H) should keep on top of the current state-of-play. At the end of the day, we are using our PCs (and electricity bills) to support their research, so they should do their utmost to keep us interested and onboard their Project. Using a Marketing tool such as "optimised for SSE4 etc", would keep us going!!! Neil.

8) Message boards : Number crunching : Default Run Time (Message 16681) Posted 20 May 2006 by neil.hunter14 Post: I don't quite follow the logic of being able to change the CPU Run-Time. I set mine at 12 hours yesterday, and sure enough, the WU ran for about that length of time. Now I have it set to 2 hours. And the model runs for two hours. My question is: Do I get more credit for longer run-times? If the CPU Run Time is too short, am I wasting part of the model, that will never then be computed? Should I leave it stuck at 4 hours as the default? Surely a slower PC will take longer to compute, and therefore the amount of number crunching my PC can do in an hour, might take 4 hours on an older P3 machine. What is the reason for being able to change the run-time? Neil.
9) Message boards : Number crunching : AMD or Intel dual-core (Message 16660) Posted 19 May 2006 by neil.hunter14 Post: Hi Well thanks to all the replies. As with most forums, the answers very quickly stray from the original question. I asked about problems upgrading my mobo/CPU whilst using BOINC and all of the answers seemed to concentrate on my PSU?!?!? For your information, I have a perfectly good CPU for my level of PC. I am not an extreme gamer so do not have dual SLI gfx cards or 4 RAID5 HDs in my box.. It's an Akasa Silent 480W ATX2 model with a nice 120mm silent fan. Anyway - thanks to BennyRop who did read my original post and has really scared me. Why are PCs so difficult to upgrade??? All I need is a faster PC, and I NEED dual-core (Intel or AMD) as my PC not only runs BOINC, but also Audio/Video software which loves duallies!!! It looks like I need to add a new fast SATA2 HD to my shopping list and to install a fresh copy of XP onto it for best results.....but I am 500 hours into a CPDN model. How do I capture this and carry on where I left off......?? (I also run SETI and Rosetta, but those mosels are smaller) Cheers, Neil.
10) Message boards : Number crunching : AMD or Intel dual-core (Message 15728) Posted 9 May 2006 by neil.hunter14 Post: Hi all, First thread here - and I am glad to be here too! I have been crunching SETI for about 4 years I think, and Climate Prediction too for a while, and now I have joined Rosetta. However, I am about to upgrade my PC. From the CPDN Forum, I was told to "suspend" my WU's, and re-instigate them after the new PC is put together. I want to go for a dual-core AMD X2 4400+ CPU with about 2 or maybe 4Gb RAM all plonked onto a nice Asus A8N-SLI-Premium motherboard. Currently, i run an old Intel P4 2.8GHz (with no HT) on an even older 845 chipset based mobo!!! HUH Can anyone see any problems doing this? My plan is to simply rip out my mobo/CPU/RAM/gfx card and stick in the new stuff using the same HDs. People on SETI reckon I should re-install XP too on a clean, formatted drive. (That's always good, but it is necessary really?) Also, does Rosetta utilise AMD X2 better than Intel 800/900 Series dual core CPUs? Any thoughts? Best wishes, Neil.
