1) Questions and Answers : GPU applications : Perhaps stupid question ! Can I put 2 differents GPU card (Message 1923594)
Posted 10 days ago by Profile marsinph
Hello everyone.
My host :
Mainboard : Asrock Z77 Extreme 4 ( )
Like you see it have a 3D Vision GeForce 570 (2GDDR5) .

I have a unused MSI GeForce 660Ti (2GDDR5)
Can I put it on MB ?
Of course no SLI between the card.
First essential question : Win7 will accept it ?
It are similar GPU, same drivers.
If yes, can I assign a project to one card and a other project on the second card
and lest SETI only run on CPU (it is already now on all my computers.

Hello Matt,
I also not find a good idea to post a forum on all other media.
Well advertising for SETI and BOINC.
I fully agree with all others remarks here below who have doubt and very good reasons about doubts.
Keeping it here, as subforum seem me the best. And by the way, it stay between Seti users.
No external unwanted person..
3) Questions and Answers : Web site : Team merge / fusion / absorption ! (Message 1917677)
Posted 8 Feb 2018 by Profile marsinph
Hi everyone.
I really do not know where to post this message. It is more a BOINC matter instead of SETI.

I see in my country very little team with one or two members. Always founder active.
My questions :
1. Is it possible to merge one team into a other. I repeat, "into", not create a new one by merging ???
2. If yes, how ???
Best regards from Belgium.

Hello Grant what is the name of ?
I know 119 : (download server)
but not the 127 ! So what is the name ? I will add to my host file)

And now we're starting to pick up work, downloads are stilling.
Tried both and in my hosts file.
No joy.

EDIT- tried again and stalled downloads cleared.
5) Message boards : Number crunching : 100 WU limit for GPUs is too low. (Message 1913768)
Posted 18 Jan 2018 by Profile marsinph
Like I wrote, why not a variable amount of WU based on computer average turnround time.
So to increase cache and also to not overload the system

Basic start : computer run 24/24 and 7/7
For beginner (RAC and/or credit : 0 ) : 50 WU (there are so much WU out in field waiting crunching)

actually 100WU
divide by avg turnaround day
x 10 days work (or depending the settings)
/ 2 to let WU for evryone (unless splitter will never produce enough work for everyone
It will give in this case 500 WU

The same powerfull computer working 12 hours a day will also have a turnaround of 2 days
So it will receive 250 WU

With this easy calculation it not depend the power of computer.
A PC power 10 with avg 1 day will receive the same as a twice powerfull with avg 2 days (perhaps it works 6hr/day)
A PC 1/2 powerfull but avg 0.5 day also the same perhaps oy works 24/24.

With such calculation, everyone have the same cache time depending crunching, depending crunching. How more sent WU, how more cache.

Of course it not need a calculation to ten or twenty decimals. Only two decimal is enough.

For the one with super powerfull calculator, no problem. And if one of it crashes, there will be more results "out of time".
OK. BUT !!! I really think it will be less than thousand of computers with 100CPU and 100GPU, who have never run any tasks !!
For beginners, the turnaround will very fast increase depending crunching.

Advantage of such way of going : reduce amount of WU out in field or waiting validation. ( I have WU waiting calculation since october!!!)
I am sure a lot of you too.
It will also reduce the servers "waiting validation" about 3,000,000 WU !!!

Hello Gary, also a nice idea about flops, but not forget that some of us let computer run a few hours/day but with very powerfull computer.
Some less powerfull, but 24/24 and 7/7 (my self)
So not easy !

Is there a 'better' database to use than Informix? What does Google use, for example? SQL by MS? And is it practical to switch? Though I have heard of Informix for quite some time, I just Googled it and found that it is an IBM product. I guess I am old, but I thought that IBM had a reputation for doing big iron, and a solid DB? Or has that ossified over the years?

*edit* Just took a closer look at the quick blurb on Google, and this caught my eye: Stable release: 12.10.xC7 / June 15, 2016. I can appreciate having something just work if it ain't broke, but I don't know, it seems to me that over 18 months between stable releases seems like a pretty long time in the compressed IT world we live in now. But then again, what do I know? ;-)

It is the BOINC master database which uses mySQL rather than the science databases that use Informix. The issue is more how SETI@home uses the database.
For all of the tasks assigned to hosts, "results out in the field", the task information is stored in a single table.
So when tasks are assigned, reported, or a host doesn't an update then that table is accessed.
For the hardware running the db the limit of that table turns out to be around 11,000,000 rows. Then it can not longer complete a query fast enough. Which causes the db server to stop and the project to be offline for several hours if not days which recovery is run.

So the solutions are
1) Have more hefty master and replica db servers.
2) Recode how the results are sent to hosts are stored.
3) Limit the number of tasks sent to hosts.

#1 is a stop gap until that hardware hits its limit.
#2 is probably the best solution, but requires dedicated time that isn't available to the project.
#3 easiest to implement and can be adjusted if the db server gets near the limit again.

#3 is the opposite of the thread title. One other thing that can be done is to shorten the amount of time until a report is due. The should shorten the queue of workunits out in the bushes and also let more workunits validate faster. However as Seti allows phones to crunch, I'm not sure how much shorter it can be before many of those low crunch able phones would start missing deadlines. Perhaps some sort of dynamic deadline based on the reported FLOPS?

Posted 17 Jan 2018 by Profile marsinph
I am happy, I got 23 WU on one of my computer. Just enough for four houyrs GPU work

Sorry, Correction, I got 150WU. SETI is back . I hope for a very long time.
Well done Berkely.

Posted 17 Jan 2018 by Profile marsinph
The little "Bruno", have now more than 5,000,000 waiting "db purge" and of course it will increase more and more.
Very soon it will be a bottleneck on it ! It status is "not running". Strange, Not the server itself, because other programs seems run normally.
I only try to understand !
I am sure all the team at Berkely try and do the best they can. Since degin december there are more and more problems after weekly outage.

And no any news from the staff. I understand they prefer to solve the problems. But it will be nice if they publish informations. It will reduce the amount of message on the forume from people who not knows what happen.

Regards from Belgium.

To mederator's, not move to "Panic mode". It is quiet different. It is only about and to the staff. Nothig to make with "crunching" or "panic"...

I just get 36 WU !!!
12) Message boards : Number crunching : 100 WU limit for GPUs is too low. (Message 1913256)
Posted 15 Jan 2018 by Profile marsinph
As I just learned there is a maximum of 100 WUs per compute device, or device class, and with an average of about 4-5 minutes per WU, that's a maximum of about 8 hours of work I can store, and with the splitters out all the time recently, this really doesn't cut it.

I'm already out of work for two hours with the current outage.

A cache of 100 tasks is only about an 8 hour cache for my dual E5-2670, or R9 390X as well. When we have shorties it is even less.
There are a few options to handle running out of work during an outage.
1) Have a backup project in BOINC.
2) Let your system(s) have a break when they run out of work.
3) Not run the project.

Hall, so if i understand enough, you ask to not more run SETI. OK
I wil do and follow your proposal !!!
Consider my suggestion about increase max alowed WU for veru acive users (like you)

Posted 15 Jan 2018 by Profile marsinph
Since a few weeks/monts, there are server outage. We all know it.
With result that a lot of cruncher are out of work after a few hours or day

We all known that it is a limitation of 100WU/CPU and 100/GPU.
Not depending of 10 days WU and 10 days additionnal WU.
It nothing change. Still 100 CPU and 100 GPU.
I understand the limitation because some users download WU, then nothing more do with results of many WU "out of time".

More and more we have powerfull computers and GPU. For a lot of us, we runs thoses WU in less than 24 hours. In case of outage, we always are out of WU.

Why not increase the limitation based on the RAC or based the turnaround time average (better i think) ???
To be clear : basic (new) user, max WU amount 100. Based on 10 days
Average 1 day : 1000 WU
Or turn around average of 5 days, then 500WU

Hello Chris, I know ! I am not stupid.
My post is only about the fact that nobody at Berkeley send information.
Sorry for my english. I try to do my best. Without electroncic transaltor. Only from my little knownledge in Shakespeare languague !
Kind regards from Belgium

No any explanation from Berkeley and staff !
Of course, they can not always publish. But a little word from staff helps !
I also not forget the time difference between Belgium and Berkeley (9 hours)
It will says it is already 10.00AM there.
Soon we perhaps will miss "The" signal we all of us are searching....
Because limitation of 100WU (understandable) i am in a few hours out of WU on all my computers..
And I ask work for 10 + 10 days.

So to conclude : it will be nice if staff post situation report.
Of course no reaction are needed on my post
Best regards from Belgium.

Posted 23 Nov 2017 by Profile marsinph
On the same computer some WU runs faster but receive higher credits than other.
Some runs slower and receive also higher credits !
Also for the same running time there are big difference.
Of course for similar WU (same version) !!!
I not compare WU running on GPU also not compare AP with other

Who can explain ?

Posted 22 Nov 2017 by Profile marsinph
Not be afraid ! How faster your run task, how slower the will be validated (not everyone run very fast and/or 24/24, 7/7).
My turnaround is less than one day.
At me :
all : 1615
in progress : 600
Pending : 538 (and always above 500)

Next 20
