Our O2K churns 24/7 on 7 of its 8 300s/250s and it's easily keeping up with some of the higher clocked x86 beige beasties that the code was optmised for (speculation, but it makes me feel better) :twisted:

Hey, don't knock your R5K 180.... the more SGIs we can get churning on this the better. We are team nekochan (SGI to the MAX) after all ;) Besides we're about to crack the top 500 and we don't want Joerg to get all the glory :D

Hi all, I just revive this thread instead of starting a new one.

I just installed Boinc with Seti as explained by nekonoko earlier in this thread, but I have some small problems on my Origin3400:

1) I often get this

Code: Select all

2006-01-15 22:50:52 [---] Suspending computation and network activity - user is active


How does Boinc detect wether a user is active? My machine currently has 16 R12K CPUs, which where at 99.5% idle while above message popped up.

2) The second problem is, that my client seems to post too many request too get any workunits at all. I always have entries like this:

Code: Select all

2006-01-15 23:00:57 [---] Insufficient work; requesting more
2006-01-15 23:00:57 [SETI@home] Requesting 69120.00 seconds of work
2006-01-15 23:00:57 [SETI@home] Sending request to scheduler: http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi
2006-01-15 23:01:00 [SETI@home] Scheduler RPC to http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi succeeded
2006-01-15 23:01:02 [---] Insufficient work; requesting more
2006-01-15 23:01:02 [SETI@home] Requesting 69120.00 seconds of work
2006-01-15 23:01:02 [SETI@home] Sending request to scheduler: http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi
2006-01-15 23:01:06 [SETI@home] Scheduler RPC to http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi succeeded
2006-01-15 23:01:06 [SETI@home] Message from server: Not sending work - last RPC too recent: 6 sec


It seems that my machine is asking for work two times in a row, which is then always answered with the "last RPC too recent: 6 sec".

I have it running for about two hours now, and while my x86-box is getting work-units without any problem, the Origin get's none.

Anybody experienced this problem before? And yes, I checked if there is a second instance of boinc running.

best regards and thanx in advance for any help

I get the above messages all the time on all my boxes, IRIX and wintel. Is any work running? As for the first message about suspending computation and network activity, I get these mesages every once in a while. I do have problems sometimes with pulling new work down from the server. Some boxes are able to download new workunits and other just defer communication. I think its a problem with Seti itself.

I sometimes get work on my Win-Machine, but it is far from satisfieing. I'd say it is working maybe 2 hours a day, the rest it is either waiting to get new units or to post completed units. And I have already played around with some settings as supposed in the official boinc/seti forum.

In the last 31 days, my winbox made around 7000 "points".

With Seti-Classic, my servers and workstations where working at 100% all the time.

The Origin - until now - didn't get any work units. at this very moment, my winbox also has the status "wartende scheduleranfrage", which I would translate to "pending scheduler-request"...the status it "works in" most of the time.

Is it just me or is Seti quite broken since it moved to Boinc? Is anyone here getting work units on a regular basis to keep their machine at 100% 24/7?

best regards

I think what you may have to do is that if you're going to run a bunch of units, once you get the machine registered tell it to download 5 or 10 days of work at a time, so even if only 5% of the requests go in, it always has fresh data in the cache.

fixed the problem

I changed my boinc setting so that it runs always (didn't know I have to tell boinc this) and that it should keep a cache of 10 days.

first, my origin-client didn't update the settings, so I added them manually to global_prefs.xml

now everything works like a charm, three cpus currently at 100%, and I red in some forums that it takes some time until boinc uses all...*crossedfingers

Actually, you do it on the Seti website, you assign 'classifications' for your different machines once registered, and define operating profiles. The next time the client connects, it will update preferences automatically.

http://www.setiathome.com

(though this will fall through to the Boinc site proper)

You can also turn off the 'Suspend if not idle' behaviour this way too.

thanx for the great help, dr.(how fitting ;) ) dave

I found out how to change it just a few seconds before you postet, but your advice definitely made the difference. now everything works :)

at first - since the origin didn't update the global_prefs.xml - I thought I had to update it by hand (that's why I wrote that first, but editet my post after I noticed it DID update the file after a while).

thanx again :)

How to prefetch workunits? I also have the problem that there is not enough work for 24/7. The dnetc works much better btw. but the mips cpu isnt a outperformer...... :|

go to your settings page:

setiathome.berkeley.edu

Change the "General Preferences".

The somewhat misleading preference "Connect to network about every" has to be changed to ten. This does not mean that your machine will connect every ten days, but it will influence the caching behaviour, thus your machines will fill their cache with ten days worth of work units.

I also changed the settings to even work when there is user activity.

Now, you can either wait until your boinc client downloads the updated settings, or you can shut down the client and restart it with -update_prefs to get the on program startup.

After I changed this value, all my machines filled up their work unit cache to the max, and are crunching 24/7 since 2.5 days.
