Message 1503039 - Posted: 12 Apr 2014, 5:21:35 UTC - in response to Message 1502588.  

... Somebody's got to do them, and the project (with a bit of nudging from a subset of GPU users) have decided that they're best done on CPUs.

Would be interesting to see how current NVidia GPUs would handle VLARs.
I've got a couple of Maxwell GPUs (GTX 750Ti) and shorties take almost 40% longer to run than they did on my GTX 560Ti, yet the longer running WUs take about the same time (no more than 5% longer).
When Lunatics release their next update that's been worked on to take better advantage of the more recent hardware, hopefully the shortie processing time will drop down to where it was, and the longer WUs will drop down as well.

Rac is now at 4250. I still have 55 pendings from the lunatics Apps.

@ Grant- Maybe that might be something that the beta testers could do. Try out VLAR's and or VHAR's On the higher end cards. Or if not beta testers, Maybe some brave volunteers from the GPU crunchers.

I thought that pendings would go far faster while running stock. Im guessing cache size comes into play?

One of those 55 is a stuck AP which won't validate and affect the test unless the staff does something. The rest will probably validate gradually enough to not shift RAC very much. Nothing you do will change how fast the wingmates finish their tasks.

You could have avoided that pendings effect by forcing the host to get a new hostID at the beginning of the test, so it would have started at RAC zero and be working up to wherever it will stabilize. Something to consider for the second phase...

RAC is at 3600 and still falling. I still have 47 pendings from Op apps

However I just found a boenhead move that I made. I set dont use GPU from my account page wrongly thinking that it would just stop GPU work for this test machine. Well it also stopped it for my I7 3770 rigs also. So I will set NNT for this machine check the box for GPU use in web prefs and then use the local preffs for this machine and stop GPU use. Is that the correct way?

I should have rememberd that as I have used local preffs before.

No

The correct way is to:

1) 'Add separate preferences for work' (may be any of 'home', 'school', 'work')
SETI@home preferences

Edit those 'Separate preferences for ...' to make them how you wish


2) go to 'Computer 5065145'
http://setiathome.berkeley.edu/show_host_detail.php?hostid=5065145

... and at the bottom change 'Location' and [Update]


3) make [Update] from BOINC Manager so it knows about the change

I think the better way would be a check box with the statement- For this computer use local prefs only. Then set what you want.

I understand what you say, But what if I had say 5 computers in each of those home ,school ,work settings. But I only had one I wanted to test? Id still have to do a local setting. But maybe Seti@home needs to get away from a website approach and go with a individual computer setting?

IE- So when you do add another cruncher and sign up. You get to set what you want to run for that computer only. So what ever changes you make on another computer does not effect any others.

Just my random two cents.

I think the better way would be a check box with the statement- For this computer use local prefs only.

And this is that way already - the simple act of clicking [OK] on Local preferences window make the "computer use local prefs only" (for Settings that exist both locally and on web)

You confuse:
1) Local preferences are 'the same set' as Computing preferences on web
2) There are no local SETI@home preferences
3) What you set in 'Activity' Menu is not saved as Preference (not saved in global_prefs.xml and global_prefs_override.xml)
It is saved in client_state.xml (at the end of file)


If from 'Activity' Menu you set to not use GPU:
a) it affects all projects (on this computer)
b) it stops GPU Computing, not Download of tasks for GPU (as you may resume GPU Computing later)

BOINC Manager Menu


I understand what you say, But what if I had say 5 computers in each of those home ,school ,work settings. But I only had one I wanted to test?

No one in the known universe ;) need more than 4 sets of Preferences
(they may implement more e.g. 'junkyard', 'jail' but will anyone use them? ;) )

I am confused. On more than one occassian I have messed up by using the wrong way to set a preference. And I just found out that you do get GPU work units even though you suspended use of GPU.
I think my test is turning into a cluster ^^%& By me not knowing how to do simple things. Thats why I am not a volunteer tester.

So, I take it that on this computer when I go to Add Seti@home preferences for home. That it will only take effect on this comouter? I have never even looked in that before. Sorry for my ignorance. Im an old dog trying to learn new tricks. And I do thank you for trying to help me.

Edit- BilBG I followed the links you gave and now computer 5065145 show up as work. I hope that my changes took effect also. I have a headache.

It will have effect only on computers of that venue. To set venue you need to manually allocate particular host to particular venue in hosts's properties page.

By default all host in the same default venue. So, if you change venue only for single host and then change that venue then only one host will be affected. If you only change venue but no hosts allocated to it then no host will get any changes in properties.

I am confused.

OK, I can confess I was very confused when I first started with BOINC in 2007
The idea that some program can have Settings which you need to change on web page was confusing for me.
And till now I don't know any other program that need web settings (browsers may have features like 'web sync for bookmarks' but they are not mandatory)

Now BOINC receives what is set in SETI@home preferences in sched_reply_setiathome.berkeley.edu.xml and saves it in account_setiathome.berkeley.edu.xml

It is/was possible to make/design BOINC so it get some XML file from projects which describe what may be changed and choices (e.g. list of applications) and then BOINC Manager have window in its interface (based on that XML) to edit this particular project preferences (then sent them back to project server).
But that will make another confusion - this way, using BOINC installed on a single computer, you change global Settings (for this project) for all your computers.

Obviously it was deemed better/easier to make people go to web page and change settings using a browser.


Edit- BilBG I followed the links you gave and now computer 5065145 show up as work. I hope that my changes took effect also.

You can check this in account_setiathome.berkeley.edu.xml

You will see something like this:
.....
<project_preferences>
<resource_share>100</resource_share>
<no_cpu>0</no_cpu>
<no_ati>0</no_ati>
<no_cuda>0</no_cuda>
<project_specific>
<format_preset>Custom</format_preset>
.....
<app_id>2</app_id>
<app_id>11</app_id>
<app_id>12</app_id>
<allow_non_preferred_apps>1</allow_non_preferred_apps>
</project_specific>
<venue name="work">

Nothing new, RAC is 3200 and still dropping. I have 40 lunatic work units still waiting to validate.

And thanks BilBG for explaining about venues to me. I made some changes in them and I hope I did it right. My other two machines are running GPU's again.
I have 100 GPU work units on (this host That will time out more than likely. Should I just abort them?
I made sure that I wont get anymore by checking the no GPU box in the work venue fore this machine.

Yes, just abort the GPU tasks so they can go to other hosts. They seem to be all cuda23, and the quota for that is already at minimum so no change there.

An alternative approach would be to set NNT, let all of the CPU tasks finish and report, then reset the project. That would make the GPU tasks be resent as CPU tasks, at least most of them. You could boost your cache settings to over 5 days to allow all 100 to be resent. But with 8 CPUs there would be some time with idle CPUs at the end of finishing the current CPU tasks. This approach would also effectively add about a week to the turnaround time of the tasks now showing as GPU, so I think aborting them is better.

Sometimes you learn things better by doing it the hard way.

You may find it interesting to compare your i7-920 to my i7-860 as you run this test. It is running 4 tasks, HT on, MB only, & the SSSE3x opt app. It was my old HTPC & has only been going for about two weeks. So is still working on leveling out.

Hal Do you run AP only and accept MB when AP isnt availible? Your RAC for the 860 is a bit higher than when I was running a mix on my 920. Plus you dont have a GPU either so Im impressed.

It's MB only. It looks like it may level out around 3500 according to the daily numbers. Once it does level out I think I will set it to 8 at a time to get the numbers from that.

Greetings Hal,

I too am running an i7 860 processor. I was wondering if you have an overheating problem with yours? My 860 likes to overheat really easy, right from the build. It will not run with the stock fan. I have a Corsair cooler installed to keep the temp down. I have to suck the dust accumulation from the radiator about every 6 weeks or so. I also use TThrottle to help keep the temp down. I can only run on 6 cores safely. If memory serves from a few years ago when I researched the 860, I found that the temp threshold was at 72 deg C. Any thoughts? I do plan on doing a new build within the next 6 months, so this question may become moot. ;)

Keep on BOINCing...! :)

In warmer months, as my central AC is a bit rubbish & ~30 years old, it would have issues. So I bought a Thermalright Venomous X RT for it. I only just cleaned the dust out of it a few weeks ago after 3-4 years of running 24/7.
