I have been running setiathome for several years now. I have recently begun running several servers from that machine, and the 100% cup usage caused by seti is lagging the servers immensely, and im afraid if it dosnt stop i will have to discontinue using seti, which i really dont want to have to do, does anyone have any ideas?

Difficult to say off hand as i run Seti 24/7 on my system & it has no effect on any of the other programmes i run (video playback, audio & DVD burning, surfing the net, stuffing around with databases etc).

I have been running setiathome for several years now. I have recently begun running several servers from that machine, and the 100% cup usage caused by seti is lagging the servers immensely,... any ideas?

Are those servers now rather old and so just 'appear' slow by today's standards?

Are they Windows servers that are being crippled by the anti-virus software?

Or are you just loading them up more with greater work?

Generally increased utilisation??

Good luck,
Martin

It is also possible that yours "servers" are running at too low of a priority and having to fight seti for CPU time. Check the priority of all your server processes.

I discovered that turning off the antivirus check on read for the BOINC directory hat a huge effect on the runnability of the rest of the system. Someone else did it the other way and turned off the antivirus check on write for the same directory tree.

I've always found that turning off Windows and booting to Linux had a huge effect on the runnability of the system. :)

No but seriously, at work I do this all the time to certain directories to improve the perceived speed of the system. BOINC runs at such a low priority that I doubt it interferes with other processes (but I could always be wrong). Another way to improve this would be to change to interval at which boinc writes to the disk. You can find it under your account preferences.

LOL!

More seriously: Yes, both very good moves.

(Microsoft is the only OS I know of that supports viruses...)

For a file server that I converted from Win2k to Linux, the only complaint I got was that the server seemed 'faster' :)

Check your Latin for the plural of "virus" (but that's another thread ;) ).

The latest Microsoft OSes provide various features and readily accessible exploits that provide the facilities that enable "mal-ware" to spread to other Microsoft systems.

Now ask yourself why this simply does not happen on all the other OSes out there on the internet. (And no, it is not because Microsoft systems are the most numerous. The internet is run mainly by non-MS systems.)

If it doesn't make a big enough impact it won't make the news. If it doesn't make the news then the loosers egos don't get their boost.

wow, thanks heaps for allthe replies guys, i wasnt expecting much of an interest. Ive already tried giving boinc a low priority and it didnt work, still 100% CUP usage. Ive noted it seems to use little I/O as far as the hardware is conserned. Im running a 2.4 ghz machine so i dont quite understand how it could be fighting for a lack of procesing power. Unfortunately my av dosnt allow to stop monitoring a specific folder, but im curious as to how this would interfere with seti itself, i have a few other programs running that monitor file activity, and i suppose it could be one those. Im going to try the lowered priority again just to be sure, will post again soon.
Thanks again :)
EDIT: and for those of you wondering what is running is slow, its my ftpd, httpd and two idling mirc clients, in addition, azureus(java) runs incredibly slow.

...tried giving boinc a low priority and it didnt work, still 100% CUP usage.

If no other higher priority processes are active, then Boinc will take whatever CPU time is spare. If Boinc didn't soak up the spare time, then you would have the system "idle" process take 100% CPU. (Yes, there is a process named "idle".)

...what is running is slow, its my ftpd, httpd and two idling mirc clients, in addition, azureus(java) runs incredibly slow.

How do you know that they are running slow? If there is no activity, then they should not use any CPU time.

Are you sure it is not just internet connectivity problems?

Good luck,
Martin

Now ask yourself why this simply does not happen on all the other OSes out there on the internet.

You missed my point. 'Support' would imply functionality added for that express purpose.

That goes into some rather subtle semantics.

Judge for yourself with this analogy:

Most private buildings are built with doors that have at the very least locks on the external doors. (Also note that 'for some well known reason' most cars have locks as part of the doors and also a lock on the start controls.)

And then you have just this one 'naive' builder that uses doors without sensible locks and markets this feature as being more 'cost effective' and quotes the advantage of unfettered easy access for the owners. Unfortunately, in the 'real world', not quite so 'naive' people see new business opportunities there. A side effect of all this is that more business is generated for the insurance companies, the police, and 3rd party security companies... (The owners also suffer a lot of upset, disruption, and paranoid fear of 'when next'.)

(And that one (supposedly 'naive') builder is also greatly more profitable than all the other 'more sensible' builders in the market.)


(OK, sorry, really bad pun on doors and windows ;) )


Can we really insist (or rely) on EVERYONE being completely honest and 'law abiding'?

Martin

Sorry to come back in topic, lol, but you should consider using threadmaster and/or limiting the amount of memory used and/or add memory ...

I use threadmaster and from celeron 450 up to athlon 64 3000+ it's working fine.

And I don't consider Windows as an "easy to use" OS. May be for nuts effraid of going into the OS, but otherway if you've got a problem of virus or so the only way to repair is to made a new install. Simple I'm not sure, but time consuming certainly !

So then you're saying that this builder 'supports' theft? ;)

That depends on how freely you interpret the term "supports".

In my view: whether by crass negligence, or by clever subversive business design, there is a certain tempting 'enticement' openly offered to criminal or just simply mischievous people. Regardless, the environment is created that supports all the adverse problems for the unfortunate owners.

All the criminal/mischievous infestation problems could have long ago been eliminated. Obviously, it must not be in the builder's business interests to add sensible locks. And the builder laughs at our expense.

By the sheer weight of complicity, I think "supports" is an appropriate description for the unnecessary vulnerability to subsequently becoming a victim foisted upon the owners.

(One particular builder is especially expensive and does insist on EULAs that give a very poor deal for those somehow agreeing to the deal... :(

I like this one

WE have a Nix user and quoting that Nix does not have this problem... Seti/BOINC runs at 100% plus or minus what it can grab from the CPU... If things work well it correctly gives up the time slices to do what the user needs to do...

In his reply it states

ftpd, httpd and two idling mirc clients, in addition, azureus(java) runs incredibly slow.

are running slow... Normally I would associate anything that states ftpd or httpd with a Nix system... As it was not stated what the server was, then it is difficult to say about anitvirus Win/Nix and how to turn it off...

In nix it would be Nice... Win is a different matter...

So the point is to either help fix the problem or get off the OS war...

WHAT OS are You running?

...tried giving boinc a low priority and it didnt work, still 100% CUP usage.

And I though the first replies were OS-neutral. The OS-war stuff came later and there's too much of that already.

Hence the answer gave the most likely pointers covering both most common OSes. (And web server stuff can be run on Windows systems also. The mirc comment suggested Windows, the others suggested *nix, hence answer for both.)

So the point is to either help fix the problem or get off the OS war...

WHAT OS are You running?

Both and sometimes others also (if you hadn't guessed).


(And reread the thread before targetting just one example for the entire thread.)

Good luck,
Martin
