Message 4290 - Posted: 29 Mar 2015, 13:23:29 UTC - in response to Message 4284.  
I discovered (with 32GB of RAM ...) that RAM usage crept up and up.
...
The computer runs 24/7 ...So...what I do now is Reboot once per day.

You have to have some program with very serious memory leak (bug) to fill 32GB in one day.

(I have 3 GB of RAM for Windows XP - sometimes I don't need a Reboot for weeks.
Only restart per 2-3 days the only program with memory leak here - cracked (by Russians) Skype 4.2.0.187 - I hate the new Skype
(No, I will not 'update'; No, I am not afraid of Russian cracks)
)

Which program uses so many GB of RAM is easy to see by any of:
Windows Task Manager
Process Explorer
Process Lasso
System Explorer
ProcessHacker

(no need of links - first result in Google is OK for all of them)

I had memory problems on occasion. www.wisecleaner.com took care of it. Hope that helps.

Several programs I use have "Memory Clean"/"Memory Usage Trim" Options:
Memory Cleaner (Koshy John)
Process Lasso
System Explorer

In fact all such programs call standard Windows functions to do the job

Usage of such programs/tools to "Trim Memory Usage" of processes may be helpful up to some point.
Windows do this "Trim" by its own when an active program want more Memory then RAM is free at the moment.

The real cure is to find the 'bad' (RAM leaking) program, then find different version which don't have the bug or find alternative program for the same job.
If no alternatives/versions are viable - restart the 'bad' (RAM leaking) program as often as needed (e.g. once a day).

P.S.
BUT I don't think that the Atom CPU that was in the beginning of this 'RAM talk' have any issue.
The Atom is just not so fast ;)

Same here, pretty much 100% failure across all my systems.


Same problem with my systems. Will be back later.

Looking over the US Navy team members task downloads most 'error while downloading' occurred at 04:00 UTC time 3/29/2015. Some members are now receiving some work units but many have just stopped the Asteroid@home project for now.

I tried something else, I didn't cancel the workunits. Unfortunately I was without internet connection during the weekend so I couldn't do anything else or check it.

I had there estimated time 2000 sec, after day it growed up to 20000 sec

Usually BOINC, when you start on some new app/project, 'thinks' the opposite - estimated time is 10x more than real.
In your case BOINC did it (estimation) wrong somehow the other way.

As you can guess it is not possible Xeon 3.00GHz to do this same task in >9000 seconds by AVX app and your Atom 1.66GHz to manage to do it in 2000 seconds by SSE3 app

Estimation should become better after you do some more tasks.


yes, i know that atom CPU is like a CPU unit of an calculator, but i have another mobile CPU attached on another project, it is intel pentium M 1,7GHz and is working on tasks without any issues, when is on some task written 32000 secs, then it will do it for this time,... and it is older CPU as intel Atom with 4 cores (2 real cores, 2 threads) and 64bit architecture... so it is strange for me, that the newer mobile processor is slower on this project as an 15 years old CPU...

Is the pc stopping crunching at some points? If it doesn't crunch 24/7 that could be the problem.

... but i have another mobile CPU attached on another project ... when is on some task written 32000 secs, then it will do it for this time,...

On this "another project" (SETI@home):
http://setiathome.berkeley.edu/show_host_detail.php?hostid=7522532
... this Pentium M processor 1.70GHz CPU have "Number of tasks completed 41":
http://setiathome.berkeley.edu/host_app_versions.php?hostid=7522532

So BOINC had time/'experience' to show you better estimated time

Check what BOINC knows for your Atom on this project/apps by yourself:
http://asteroidsathome.net/boinc/host_app_versions.php?hostid=154098

***

In the task there are no 'written' seconds, instead it have <rsc_fpops_est>XXXXXXXXXX</rsc_fpops_est>
(the Copy/Paste is from my client_state.xml from 26.03.2015 copy)
<workunit>
    <name>period_search_1010_1426497677.081390_228913</name>
    <app_name>period_search</app_name>
    <version_num>10210</version_num>
    <rsc_fpops_est>55757157098049.469000</rsc_fpops_est>
    <rsc_fpops_bound>5575715709804947.000000</rsc_fpops_bound>
    <rsc_memory_bound>64000000.000000</rsc_memory_bound>
    <rsc_disk_bound>100000000.000000</rsc_disk_bound>
    <file_ref>
        <file_name>input_4801_69</file_name>
        <open_name>period_search_in</open_name>
    </file_ref>
</workunit>


fpops_est = Floating-Point OPerationS _ Estimation (this is Not per sec, this is Estimation of total needed fpops to finish the task)

BOINC uses rsc_fpops_est (which is set by the project) and several other factors (which estimate in general the speed of the computer system) to show estimated times.

You may just not pay attention to BOINC estimates or you may go crazy ;)
If you really want to go crazy:
https://www.google.com/#q=boinc+estimated+cpu+time+remaining
https://www.google.com/#q=boinc+estimated+cpu+time+code+rsc_fpops_est

http://boinc.berkeley.edu/trac/wiki/CreditNew

***

http://boinc.berkeley.edu/trac/wiki/RuntimeEstimation

The only case when the estimated time matters is when it is 'too' low

As you can see by this two lines:
<rsc_fpops_est>55757157098049.469000</rsc_fpops_est>
<rsc_fpops_bound>5575715709804947.000000</rsc_fpops_bound>
... here on Asteroids@home the task is allowed to run at most 100x times the initial estimate (after that it will be auto-aborted by BOINC, this is to avoid hang apps to run 'forever')

On SETI@home this was (~year ago (?)) 10x and now is 20x

Hi Boss,

Any idea of a timeframe to sort the download problem out?

Could the download limiting server software be changed so that it doesn't count Download failed as a reason to stop a computer from downloading more workunits?

That should help get rid of the workunits set up with missing input files on the server faster, without the current restriction on how many good workunit get done each day.

I've found that there is no need to abort workunits with Download failed - just use the normal method for reporting them back to the server.

So what is currently the suggested action from the users? Keep going through the faulty WUs, or don't bother?

Looking at a tcpdump of my traffic to ateroidsathome.net, and trying the URL in a web browser, it seems that instead of the WU's data, the server provides just the 39-byte MD5 sum. Going by the presence of "Content-Location" header and its contents, I'm guessing this is caused by a misconfigured mod_rewrite in apache..?

Sounds like too many errors were reported so your work fetch has been throttled, this is standard at alot of projects, but since you have your pc's hidden I am only guessing. As you return valid units your daily quota will climb rapidly, if I am remembering right it's almost doubled every day as long as no more errors creep in again.

If you go to:
http://asteroidsathome.net/boinc/download/317/

,,, you will see that input_4532_19.md5 exists but input_4532_19 is not there

Kyong (the admin) say it is caused by BOINC server and re-using "same input name as before"
"I have checked how the BOINC server is checking the input files that have the same input name as before"
http://asteroidsathome.net/boinc/forum_thread.php?id=424&postid=4212#4212

Seems that BOINC server prematurely deletes WU files

Looks the download failure rate is 90%+. I've had 4454 failures to get 413 tasks that can be run since March 19th.
Makes no sense to me why this issue has not been fixed.

Well, the reason is very simple: Administrator of this project is busy. Obviously he hasn't had enough time to do it yet. He will fix it when he has enough time to study what causes the problem plus apply the fix.
