well I have problems getting the pre-release V8 running on my 8-core mac pro

tried everything im running boinc 5.4.9 via the command line (i have tried 5.8.17 as well with less success)

using pr7

this is the error i get:

2007-04-26 12:15:26 [SETI@home] Process creation (../../projects/setiathome.berkeley.edu/seti_boinc) failed: Error -1

i have checked and re-checked permissions etc but cant think of anything else to try

i also used version 5.8.17 which gave the following error:

Thu Apr 26 22:21:51 2007|SETI@home|Restarting task 12fe05ab.23077.4738.104832.3.52_1 using setiathome_enhanced version 513

repeatedly

perhaps one of you kind gentlemen can email me the previous pre-release just to check if it just this version

i must say its rather frustrating (but damn impressive !!) watching zombie et al racing towards 10k and i'm probably gonna hit 6k :-) ho hum.... im sure i can cope...

so any ideas people ?

... Give me a couple days to get the PowerPC builds up and running. As you may already know, there are things that I did for v7.2 for x86 that weren't in v7.1 for PPC, so these alone should provide some performance gains. It remains to be seen whether the cache tuning I did for v8 will help PPC, so that means I'll need PPC testers once the code is almost ready. For that matter, I need testers with Core Duos, since I haven't assessed the performance impact on that architecture, either.

I realize my performance tuning has been targeted more towards the leaderboards lately, but hopefully what I've learned there will soon bear fruit for everyone else as well!

Hi alex,

any news on the PPC-version?

[halimedia]

adrian - your problem may be related to insufficient shared memory available. See this page for details.

HTH,

repeatedly

This happens to mine occasionally too. Basically BOINC Manager freezes up, I get the spinning pinwheel of death, all the CPU meters zero out. It lasts for about 10 seconds, then everything resumes like normal, and the I get:

Fri Apr 27 15:33:08 2007||Can't rename client_state_next.xml to client_state.xml; check file and directory permissions
Fri Apr 27 15:33:08 2007||[error] Couldn't write state file: system rename

(repeat the last three lines 7 more times, on for each WU running)

But like I said, everything resumes as if it never happened. No error'ed out WUs, no restarting the WUs from 0.

ok heres the situation

i have managed to get pr6 running fine, no problems

so it looks like a weird zip/unzip problem i have tried every way of unzipping pr7 and it doesnt work...

anyone fancy emailing me their own pr7 rather than alex's zip file ?



halimedia... yes i have sorted out my shared memory problems (that was the first hurdle last week)

thanks for your help people

Sounds like you guys might be having permission issues, preventing certain files to be written. I'm running v5.4.9 of the CLI-client, and by manually setting permissions of my boinc directory, I have solved such issues before. Here's what worked for me:

sudo chown -R myuser:admin myboincdir
sudo chmod -R 755 myboincdir

where myboincdir is the name of the boinc client _and_ working directory. If you use sepparate boinc directories for the client and all boinc data, you may have to apply these changes to both directories. Also, it's important to note that boinc clients of the 5.8.x-variety can now setup their own unprivileged user under which to run. The script that does this takes care of any permission issues, so the above steps will not be needed.

Lastly, if you're using a v8 pre-release, make sure you adapt your app_info.xml file to include the correct name of the v8 executable.

HTH,

Ron

[adream]

ok problem solved here !

just needed to make the bugger executable :-)

chmod +x seti_boinc sorted it out...

should have tried this earlier but, was suffering from a mild case of stupidity... oh well

thanks for everyones help again, especially peter,zombie and ron

FYI, for ownership, the owner should be boinc_master, not myuser. This worked for me:

cd into the S@H folder, then

sudo chown boinc_master:boinc_project *

In any case, the error I listed earlier is apparently not hurting anything. It's just annoying.

The option of creating boinc-specific users and groups was only introduced with v5.8.x of the client, correct?

TIA,

Ron

AFAICT it’s not an option, rather part of a programme to improve security.

[zombie67]

It is my understanding that all file should be owned by "boinc_master" and group "boinc_project". Are you saying they should be something different? This is for 5.8.17.

My iMac just cracked into the top 1000 computers, it is at 927 and working its way up. RAC is 1435 and climbing.

Nope, for any boinc client version since 5.5.4, these are the correct user and group settings, AFAIK - at least if you're running in 'sandboxed' mode. I'm not very well versed with this situation, since I'm still using 5.4.9, but it is my understanding that sandboxing the client is optional at least with the CLI-version. I don't know if this also applies to the GUI-version, though.

Here's more detailed info on the sandbox-design: Sandbox design

HTH,

My iMac peaked up at about 1836 RAC but has dropped back down to 1717 as of this post. But I have climbed all the way up to 274 on the top computer list!!

In a way, considering your age, the break-up was good. I guess
that's life.

Alright...you've got us all wondering...Which post was this in reply to?

QS

[Todd Madson]

I was wondering that myself. Maybe his old Macintosh?

Anyone hear from Alex? - it's been a month. Hope he's okay.

Interesting news though - I added another gigabyte to my G5 so I now have
3.5 gigs of ram and it literally shaved nearly 20 minutes off of my average
work unit processing time. Anyone else notice adding ram speeds things
up considerably?

It is a spammer, it is in the signature.

Yes, I'm still alive. Unfortunately, performance on v8 is not yet where I want it to be on PowerPC, so I'm going to take some time to investigate whether or not I'm overlooking something. I also haven't gotten around to tuning for Core Duo, and it's possible that the gains on that architecture will be modest as well.

First of all, are you comparing work units that have the same angle range and claimed credit? I seem to remember pointing this out in the past, but comparing two WUs with different angle range is essentially meaningless. Comparing average WU completion time is similarly meaningless, since the distribution of angle ranges in the work that SETI sends out also varies over time.

If you're seeing a difference on similar WUs, the only case that I can think of where adding RAM would help is if it increases available memory bandwidth. If your DIMMs weren't installed in matched pairs previously and they are now, it's possible that you've gone from single-channel to dual-channel mode.
