Hi Christine
There is an issue with the severs and some zip uploads at the moment.
More about this Here This will be sorted out,not a problem your end.

So no need for the backup yet everything normal just a short wait for server maintenance.

Chris



Oh!!!!
I had this last night on my Linux machine - and I decided to abort...damn - I probably lost 12 hours of work or so for no reason... ...got it now again tonight on my 950D Windows system - glad I read the message.
I\'ll suspend Network activity overnight, and see if it uploads in the next 24 hours or so.

......i.e. the s/TS has kept dropping ever since the transfer - it\'s now 3.67 - but it\'s never going to show the real current s/TS.


You\'re right - it\'ll just show the average. However, if you look at \"Your Results\" and your Trickles, you\'ll see a sudden step-change in your s/TS measure.

23) Questions and Answers : Windows : Boinc running on vista ultimate not running smooth (Message 28013)

Post:

Your computers are hidden so we can\'t look at the specs - how much memory does it have? (Vista is very memory hungry and you may be seeing memory starvation).


I recently built a dual-core system, running Linux, but I thought 1Gb would be enough for the two models! No way Jose!!!
Most of the time I only have about 25-50Mb of Free RAM.
I would definitely recommend 1Gb RAM per core/thread. It also goes without saying, that the faster the RAM, the better.

There shouldn\'t be.

Looking at the page for that model, you may be having HD problems, even though the HD doesn\'t get written to as often.
Was any other program running at the time which may have been competing for hardware resources?



Probably - I think it crashed when I was using Internet Explorer, ironically, to ask about how to get BOINC running on a Linux PC!!!!!
My HD is only 3 months old so should be fine, but I may run some diagnostics on it to check. It\'s a Hitachi SATA 2, 320Gb 16Mb Cache.

25) Questions and Answers : Unix/Linux : hadcm3lb version 5.15 crashes when showing graphics. (Message 27951)

Post:
Processing workunit hadcm3lbm_azon_25282074 crashes when trying to show graphics. It didn\'t happen at the begin, but only when processing reached year 1952. Graphics window shows only Earth image up to coastlines and after that hadcm3lb version: 5.15 crashes:

Fatal signal caught, cleanup CPDN run and restart...

Tried to restart from earlier backup, but the problem reappeared when year 1952 was reached.

SYstem info: Linux, Fedora Core 6, Pentium 4.



I think the graphics takes up a lot of CPU ratio, so with a slower machine or one with only 512Mb RAM (one-core CPU) you might push it over the edge!
Having said that, I have never completed a model either and am getting very frustrated with the lack of reliability with Climate Prediction. I\'ve never had any other BOINC Project model crash, but CPDN is very, very fragile I feel.

26) Questions and Answers : Unix/Linux : suse 10.2 and boinc, does not work (Message 27950)
Posted 17 Apr 2007 by Profile old_user81594
Post:
OK I have switched over to suse 10.2 with KDE, the client does not run.
What gives with BOINC 5.4.9? sometimes it \"does\" move the counter, but about 1 second every 2 minutes. On an AMD Athlon 64 3000+ with 1 gig of memory, this for sure should be running faster. Is this client just too buggy or. . . .

Help is appreciated.


I have OpenSuSE 10.2 on KDE as well. All works fine here. I\'m running a 64bit version on an Intel 950D dual-core.

For Linux users who have downloaded a new model in the last two days

The new Linux climate models, version 5.40, were within hours discovered to contain an error. A line of code inserted for testing purposes had not been removed. When a Linux 5.40 model contacts the server, it will receive a killer trickle to abort it. A new version 5.41 model will be downloaded to replace it.

Apologies from Oxford for the error. Fortunately not much crunching time will have been wasted on the flawed models.

More project news is available through my signature link.



What about Windows models? I downloaded a 5.40 model on Thorsday and it crashed unexpectedly yesterday......is there a flaw there too??

This is discussed here on the BOINC/dev boards.




Got CPDN up and running again with Linux finally. Had a few days away, hence the break, but last night I downloaded OpenSuSE 10.2 64bit which works a treat!

I think the trickle process isn\'t picking up the new 5.40 models yet, once Carl/Milo/Tolo get back to the office they can sort it out. It takes a while for external sites to pick up credit so you\'re probably talking about tuesday for credit here, and wednesday for external sites (see Richard\'s post for a more detailed explanation).

At least you\'ll get a *LOT* of credit once all your backdated credits are processed! :-)



Thanks for this. I was getting worried that I had a \"bum\" model. Been crunching this 5.4 model now since Thursday and had no trickles (now Monday 18.30). I\'ll keep going and hope for a big bump up tomorrow or Weds then?

Cheers,

Neil.

OK. I\'ll continue with CPDN!!!
However, I can only do this if I get Linux up and running. Can someone help please?

I have Xandros distro loaded, and I have installed BOINC. On running the Client, I get a dialogue box telling me that \"GLIBC 2.4 not found (required by BOINC)\"
Can I download and install glibc 2.4 (or higher) with this distro?

Many thanks,

The problem is that 64 bit linux is not an officially supported o/s. Even though the 32 bit client apps will run just fine on it, and 64-bit Linux is becoming more popular, nobody at Berkeley seems interested in making it easy for us, yet.

I\'ve posted a couple of links below that can lead you to a solution, though it involves some work. I went back to a 32-bit version of Kubuntu for other reasons, so it doesn\'t really apply to me any more.

Option 1: download the 32-bit boinc software from boinc.berkeley.edu and edit your existing startup scripts to point to the 32-bit version of the executable. Here is a post outlining how I did it on a Debian-based distribution:
http://boinc.bakerlab.org/rosetta/forum_thread.php?id=1799


Option 2: Get the source code for the boinc_client, modify it so that it responds to the server with the reply it needs to download the 32-bit client applications. This has been done already, a link can be found at the bottom of this discussion:
http://boinc.bakerlab.org/rosetta/forum_thread.php?id=2549

Option 3: make an app_info file for each client application you want, and specify the 32-bit application request in there. The BSD folks do this, and some have done it for linux-64.




Hi all,
I\'m a little confused by all of this. I have just bought a new PC base-unit which sports an Intel 950D dual-core chip. This apparantly supports the EM64T stuff.
I\'d like to download Linux and run Seasonal Attribution on this PC.

What do I do?

I was looking at Linux Fedora Core 6 - 64bit OS

Is that a good OS to run BOINC? I need a GUI and am not into any kind of programming or Command Line stuff. I just want a straight-forward PC that keeps crunching!

Post:
I have a C2D E6400 ready and waiting for somethings it would work well at. Until then ill have my 1.9-2.1secs/ts i get now :(



I think 1.9s/TS is about right for your PC, but not 2.1.

My stock E6600 is 1.62s/TS (2.4GHz), so yours with 13% slower clock gives 1.82s/TS and then knock say 3% off for having only half the cache (guesstimate figure....) comes to 1.88s/TS.

Post:
I have an:
AMD Duron 1.8 GHz
1 GB DDR-RAM
FSB is 133 MHz
s/Ts is 4,5 s
64 K L2-cache

What is the most important for the s/Ts?
Processor runs at 100% so it doesnet have to wait for the rest of the system.

Will more ram help? if the cache was bigger, would it count?
The new PC\'s have fsb with 1 GHz speed. Is that important or is it the processor?

How much beter is a P4 than a P3 and so on
Pls, someone who knows something about this, tell me.

Thank you :-)


Well, you quoted 4.5s/TS for your old machine.
I have a new Intel Conroe E6600 based set-up and it runs at 1.6s/TS in standard trim (3 times the speed of yours and I have dual-core obviously, so I am doing about 6 times the work that you are in the same time!!!), but if overclocked, like I am currently, it is running at 1.25s/TS.
FSB/memory speed and clock speed are all interlinked. In order to get a higher clock-speed, you need to \"up\" the FSB. By doing this, allows the RAM to support the CPU better, if and only if it has sufficient overhead.

Post:
These 1.10-1.30 speeds people report are overclocked machines, and the beauty about this chip is that they are rather easy to overclock.

Mine E6600 @3.2 GHz is doing 1.32-1.35 with two models and the Linux client (which is a couple of % slower than Windows)
With one model it\'s around 1.25.
With one model + a GIMPS M32 LL test it\'s around 1.45, hmm...



Hi,

Re: Time-Step speeds.

I think you are right. I have just installed a new SATA II hard-drive, and re-installed XP and everything else. My E6600 is currently overclocked to a very stable 3GHz (333MHz FSB) @ 667 DDR2 RAM. I have on both cores 1.35s/TS.
This has dropped from 1.62s/TS on a stock 2.4GHz E6600 with 800MHz RAM. The maths says that this is completely right:

3/2.4 = 1.25 (ie. 25% quicker CPU clock)

1.62 secs. / 1.25 = 1.3 secs.

I\'m getting 1.32 which is only a smidge slower, probably due to the slower 667MHZ RAM clock as opposed to 800MHz.

Hi Neil

What you\'re losing is the gui (or Manager), which is boincmgr.exe, not boinc.exe (which is the worker daemon), or the 2 climate programs.
Yet.




....so all OK then. I can go abroad safe in the knowledge that my PC should keep chugging away!!!

Well, I\'m getting the same 1.62s/TS with both cores running CPDN. If I suspend my projects so I am just running one instance of CPDN on \"one\" core, I get 1.39s/TS.
My PC is E6600 on Asus P5WDH Deluxe with 2Gb OCZ DDR2 PC6400 (5-5-5-15) RAM.

Hi,

I\'ve just upgraded again from an Intel 950D (which was pretty impressive) to a Core 2 Duo E6600 (2.4GHz/4Mb L2 cache)

With CPDN and my old 950D, I was running at 1.9secs/TS. I\'ve just checked my current CPDN model over the last 3.5 hours, and it works out at only 1.68s/TS with my Core 2 Duo chip.
I was expecting a bit better than that. Could I just be seeing a \"slow\" part of the model?? Any others with an E6600 - what is you seconds/Timestep stat???

I thought I would be nearer to 1.3s/TS with this CPU.

Whenever I skype the software flames at me that \"my CPU usage is too high\" but that seems to be a default error message since I never had any problems... it\'s kind of a running gag between me and a friend who does BOINC too. ;-)



Interesting post!
I have problems with the BT Yahoo Browser (which I think is based loosely on the MSN Browser) and CPDN. After opening my BT Browser it then automatically loads up BT Yahoo Messenger/Communicator (Skype equivalent) and LaunchCast which is a BT Music Player that plays music based on your preferences.
After 10 minutes of so BOINC disappears from my taskbar, and then the icon in my System tray disappears 5 seconds later.

However, if I do a CTRL>ALT>DEL my processor is still running at 100% and I can see the Boinc.exe process and the SETI or CPDN process running too.

What\'s all that about??? Is BOINC still running under these conditions?
I go abroad a lot with work and leave my PC on whilst I\'m away running BOINC Projects. I would hate to find that my BOINC Client bombs out occasionally without me knowing!!!!

40) Questions and Answers : Wish list : Time to completion (Message 23916)
Posted 12 Aug 2006 by Profile old_user81594
Post:
A nice little improvement would be to get the \"Time to Completion\" a bit more accurate, and also the CPU Benchmarking. (Are the two linked in any way?)

One model I am running says it has 2090 hours to go, but from the graphics, you can see the Number of Time-Steps in the model and the Seconds/TS, so that calculation isn\'t that complicated. CPDN says I have 2090hrs to go...my maths and calculater says 1593!!!

The other model is the same sort of error, circa 20%.
CPDN says 2678hrs to go, but I reckon it has 2212 hours running at the current 1.9s/TS.

Neil
