These server software is extremely old, outdated and obsolete.


Where do you see this?


Maybe at the bottom of pages.

Hammeh,

Thanks for your response, you are probably correct in your analysis.

I too was thinking it was a failure to access a file but couldn\'t work out which one, or more importantly why this only happens occaisonally and only recently.

I have been poring through various logs etc and I think I have found the answer.

Each failure was preceeded by an entry in the event viewer system log stating that virtual memory was too low, and was being increased. Obviously this caused a lack of resources during an attempt to checkpoint.

I then realized that the second fastest of my three paging files had somehow vanished.
The fastest is fully allocated, but the slowest on C drive has only 2MB of 1000 allocated at startup. When the first is fully utilised Windows then claims more space on the C drive allocation, causing a temporary resource shortage.

This was due to a CPDN HADAM3P being suspended and a Rosetta task running, both using a lot of VMEM (total more than paging file #1).

I will reinstate my missing paging file and monitor, and am confident that this will resolve the issue.

One of my crunchers has had a few errors.

A window pops up stating that \"The application was requested to terminate in an unusual way\"


Stderror txt contains:

<message>
The system cannot find the path specified. (0x3) - exit code 3 (0x3)
</message>

An example

Any thoughts?

will rosetta use cuda/gpu crunching? my gtx295 is begging :-D

i have my i7 920, and my work computer and server rockin rosetta@home.... but i want to get those extra gpu\'s going... without running those on a different project....


any ideas?


Please read GPU@Rosetta Thread

Can anybody tell me if the units listed in Reports and plots of results from active work units on home page are still in progress, completed or a mixture?

I have noticed that a lot of them have not been updated for a long time (months), hence the question.

I have recently had a number of tasks that finish without error well before the preferred runtime.

An Example ran just 3 hrs on a 10 hr runtime.

All task that have done this show 99 decoys completed, is this a max built into the tasks?

I was referring to RAC. You are using a credit per MB of BW system. So, yes, I\'d expect that the more factors you can play together that reduce MB of download will improve your credit per MB. But, it will not make a material difference in credit per day of crunching, which is what RAC amounts to.

I\'m curious too, how did you measure your bandwidth? Are you using a proxy server that recorded that? I\'m not questioning your figures. Just looking for more ways to measure it my self :)



I am using a commercial program called BWMeter, primarily to control b/w allocations to each host on my network to stop any host \'hogging\' the internet.

I also has quite good statistics among many other features.

Yes virtual, I wouldn\'t \"sell it\" as a RAC improvement. It should be basically unmeasurable. And, as you can imagine, if a new protein come in to study during your test, then you had an extra couple of 2-3MB files to download. It really varies. So, it isn\'t even really intended to be much of a bandwidth saving. I really boils down to the number of hits on the scheduler. After that, the specific file transfers are not the main focus of changing these values.

You can also reduce file transfer bandwidth (and scheduler hits) if you keep more days of work on your machine. If you say connect about every 3 days for example, rather then the 0.1 days default, that can make a nice reduction in hits on the servers. Not that setting to .1 days means you actually always do 240 hits per day, but the higher value will reduce the number of requests.


Hi Mod.Sense

I agree that there is a large number of variables, but they do tend to average out over the longer term.

Below are the figures for 2 months pre/post which still show a significant decrease in traffic.

Even though during the post period I have noticed there have been increased numbers of new proteins and several series which repeatedly \'crashed out\' on my hosts and problems with credit generated, which would all have the effect of reducing the amount of traffic reduction I have seen.

These figures indicate a 33% increase in credit per MB of Download.

Date ranges      Credit DownMB  Ratio
16Sep08-14Nov08  25373  1196.2  21.21
15Nov08-13Jan09  30202 1057.2 28.57

Simple maths will tell you that for a particular protien, if you double your runtime then you will roughly double the number of models completed, thereby roughly doubling your credit (per MB DL).

If you still crunch for the same number of hrs per day this means your traffic is roughly halved.

I believe in the longer term my stats will approach that figure.

I was also wondering where the total credit increase came from, and suspect it may partially be due to less cpu time \'wasted\' by 1 - network traffic and 2 - loading and initialising the work unit before it can start actually crunching any useful data.

I guess more time will give more accurate findings.

And Yes - My overall servers hits have reduced considerably. (maybe by 30-40% guesstimate)

For those who may be interested in the effect of runtime changes.

Below is a list which shows credit vs down/up traffic for 3 weeks pre/post runtime change.

Weekly Dates      Credit   Down MB   UP MB
26Oct08-01Nov08   2079     150.1     6.0
02Nov08-08Nov08   2519     235.9     8.7
09Nov08-15Nov08   3222     211.2     29.1
16Nov08-22Nov08   3894     118.2     6.4
23Nov08-29Nov08   4348     120.0     12.3
30Nov08-06Dec08   2839     117.3     4.9

After this thread started I changed my runtime preferences.
Before 15Nov all my hosts were default 3hrs.
On 15Nov I changed runtimes as follows:

10hrs - 1 Host (~80% of RAC)
6hrs - 2 Hosts (~11% of RAC)
4hrs - 3 Hosts (~9% of RAC)

The List shows the obvious drop in internet traffic and increased Credit output due to changing the runtime (which was the only change made).

[EDIT] The increase in credit shown here is more likely due to variation in project crunching ratio - but overall shows ~10-15% increase since change.[/EDIT

I designed and was going to build myself a new desktop supercomputer, It would have been ~750 times faster than my current Q6600.

But then I came to a devesting realization, I dont know linux so I would have to use windows. On a computer that fast the 3 monthly BSODs would happen every 3 hours!!!!!!
