Message 224289 - Posted: 1 Jan 2006, 20:12:07 UTC

Since the influx of all the Classic members, welcome by the way, the Seti system has been stressed to the breaking point. Seems to be running on the raged edge most of the time lately. Isn’t it time we bring out the enhanced Seti cruncher? I don’t think Seti has a prayer of catching up with the current system load until they bring it out.

Can Matt Lebofsky, or any other developers, make any comments on this?

Jason, I read through your thread. Even searched for the word "enhanced" in it. Found nothing of any relevance to this thread.

Shifting to the "enhanced" Seti cruncher would accomplish many good things. All the client computers would be slowed down because it does more detailed analysis of the work unit. It also counts the actual "flops" while crunching the work unit which would eliminate the need for the currently useless benchmark procedure. This would bring the claimed credit for different operating systems more in line with each other. Slowing down all the client computers would reduce the load on the upload and download servers, another good thing. Then the servers at Boinc/Seti could keep up with the demand and the developers could go back to developing the Boinc program rather than fixing the overload problems as they pop up. I do however acknowledge that Boinc/Seti is the stress test for the entire system due to the higher number of client computers here.

Overall, I believe it is time for the enhanced cruncher.

Well ready yes. But they cannot just say ok lets do it. They have not even finished the Merge yet. With the issues with the servers the past 24 hours and the merge on standby until they gewt back to the lab...it is definately NOT time to implement a totally new platform. If they did, the increased problems on top of what we already have, would discourage the new BOINCers from staying on the project even more than they are now.

Where do you see the SETI system at breaking-point?
It is a little behind, but the transitioner backlog is falling.

What ever issues Berkeley may have at the moment seem small compared with some over the past 6 months, that I thought were show-stoppers, but every time the guys have pulled a trick and sorted it.

Right at the moment (and over the past few days) I'm downloading work, uploading work, and getting credit granted - so I'm slightly mistified about what the issue is?

I don't see any issues either to worry about.
I think before switching to "enhanced" the dev. team should sort things out and start shipping the new client after all minor things have been fixed.

Anyway i'm prepared with for "enhanced".
Got my own clients ready to go.

Hi Crunch3r,

Will you be releasing your optimized clients for Seti_Enhanced to the public when Berkeley rolls out their official enhanced client? How much time do your optimized clients save compaired to the official enhanced client?

Regards, Daniel.

Maybe they oughta just go ahead and release SetiEnhanced. This would reduce a lot of message traffic and begin to shorten the database. But- I don't know anything about how the transition itself would impact the current state of all the data and servers at Berkeley.

Hi Daniel,
we are testing them at the moment. I started my first try today on my A64 3200+.

so far after 2h30min it's at 30% but that's my first wu i'll have to see what happens when it's done.

P.S. You got my e-mail adress :)

this would actually put more load on the system, due to the requirements that need to be met for a new app (lots of new entries in the database basically)
so the DB would get bigger, and more stressed, and if by "message traffic" you mean on the fora, well, that's not a whole lot, considering most people don't post, i never did for classic, only started posting here after about 6 months of doing BOINC as i was interested in what was going on

but lets keep the big picture in focus here, they need to get a stable version of the enhanced app in the production system, a splitter or 2 for enhanced (which will need writing, compiling and testing before production release) before we'll be able to do anything related to "enhanced"

I understood that the enhanced application processes exactly the same WUs as the current app - just the enhanced application looks deeper into the data.

If that is so, the no new splitters need to be set-up. Nor can I see the need for significant database load changes.

The biggest single load I can see is 700,000 hosts downloading 1 or 2 meg of new application.

As far as I know they just have to change the 4.18 tag to the 5.XX tag. A slight change to the splitters.

And there's a lot of work to be done to get this working properly, special case is the memory allocation malloc_a.cpp which is buggy and won't even compile using intels icc etc.

But that's not of my concern.

To be onest with you all i think there's lot to do.

that are things that no one understand

i tried the optimised Client on Seti enhanced with my old Server

Windows 2000 Server SP4 and an XP 2.500+

Memory is going from 0 to

but after this is running fine of the usage of 64 MB...

it's the same data, but different splitters will be needed to generate the different header(s) needed to tell clients to use the "enhanced" app rather than the "standard" app, same data being processed, but new splitters will be needed (well you could change the old ones, but i doubt it, as they need 7 to keep up with the rate of work at present, and implementing new ones is easier and safer because it will affect the rest of the production system less than trying to change existing splitters, it's just good practice)

Nor can I see the need for significant database load changes.

The biggest single load I can see is 700,000 hosts downloading 1 or 2 meg of new application.
well, i wasn't thinking about load in bandwidth terms, merely as DB load, which will increase at first because of all the stuff that needs to be done to add a new app to the system, and all the requests by various parts of the back-end etc. and more varied requests are (from the little i know) served slower than similar requests, especially if some form of caching is used, but my knowledge of DBs isn't vast, so any DB admin's/guru's can correct me here

but yes, it will die off eventually as the WU throughput rate will drop
(but it'll be helped by people not hitting the "update/retry" button every 2 seconds!)

Evening Everyone

Everyone has questions and a few are over in Seti Beta trying to help insure that it is ready... I have one machine doing Seti, Einstein and Seti Enhanced... and two that are currently only doing Seti Enhanced. I was a bit of a Rabble Rouser when I did a Thread here about Seti Enhanced - Almost Perfect... The purpose was to get people here asking questions to Go LOOK! In some cases get more involved, it is Your Chance to help insure the next version has fewer problems... As there are few people really testing it makes things tougher... If You do not know if Your computer is up to Seti Enhanced Go Start Looking. Then "You" can decide without someone telling you the "Medicine Tastes Like Honey," really it does!

Number Crunching Forum...

Generally I have three machines Crunching.

PII 400 - 719,839.67 seconds
PII 400

PIII 550 - 523,069.37 seconds
PIII 550

AMD64 3200 - 113,153.73 seconds
AMD64 3200

If You never Go Look, then you will be surprised...

No Credits for Seti Enhanced do not count here... Your Peace of Mind does

I don't think setienhanced will stave off user overload too long. Computers are still getting faster and they did this a little bit before. They added more calculations.

true, but enhanced takes something like 10 times as long per WU, so it'll help
also computers will take quite a while to get 10 times faster, and as nice as it would be, i'm sure SETI won't get 10 times as many hosts over night ;)
