Hi,
I'm trying alpha 5.2 on a dual G5 2GHz.

http://setiathome.berkeley.edu/show_...hostid=2348351

Good job, about 2800 sec for wu :-)
With BM 5.2.13 standard about 12500 sec for wu and with an old Seti_Worker_G5Optimized_altivec 8000-11000 sec

At the moment only one invalid result:
http://setiathome.berkeley.edu/resul...ltid=295065722

I'm using Boinc Manager 5.2.13, boinc 5.3.12.tx36, [email protected] and bigfft_wisdom for G5 2GHz ( http://esa.tienhaara.net/seti/fft/2.0/bigfft_wisdom )

Hi
Sorry, may be this was discussed early, but can't found.
I have few Mac on my work and i want to use it to calculate for my SETI ( some kinde of grid computing). Can someone point me "how"?

SETI guide

This thread is for development/feedback on advanced SETI workers. General SETI questions should be posted in their own thread. If no current thread looks like a good place, start a new one. There's no cover charge.

A small update on the status of the Intel Mac version.

Turns out there's a small (but serious enough to cause major problems) bug somewhere between the x86 hardware and the [email protected] code. I've been bashing my head against the wall about this for at least a week and it doesn't look as though it will get resolved soon.

I've submitted a bug report about this to Apple so when / if this gets fixed is purely a matter of guess work (in my experience, sometimes they're fast, sometimes they're not).

It's been sometime since I was using [email protected] back in '99. I decided to give it a try once more, since I heard there were quite a few PPC-optimized workers around. I finally managed to set it up and running as I wanted to, but there are a few issues I would like your opinion on:

I started by installing the official BOINC Manager. Everything went well, but as soon as I tried to check whether my battery settings were being obeyed (I'm on an iBook and don't want the client to run when I'm on the road), I found out that although BOINC manager was reporting SETI worker as "suspended", that wasn't the case: The worked just kept crunching, although message log was reporting that it was paused. The same thing was happening when I manually directed the worker to pause through BOINC Manager's menus. That's when I decided to check out the alternatives.

Next thing I did was to install the BOINC Menu and update to the latest (a5) G4 client by Berry and Kan. I believe that's the client most of you G4 owners are using right now. Did my battery test once again (BOINC preferences unchanged) and noticed that although the worker would stop crunching when on battery power, it wouldn't start up again after plugging the power cord!

Next, I moved on to the CLI version (with a little help from this extremely well-written guide, and finally saw the true light I was looking for!

So, I'm finally up and running using boinc_5.2.13ppcG4opt as the BOINC executable and [email protected] as my [email protected] worker.

As you can see, I didn't really have much to share with you, I just wanted to share my evening quest with some people that would understand it. Thank you for reading and... if someone could check this peculiar behavior (the whole suspend/resume issue) and post back some information, I would be grateful!

A little update, My G5 1.8 mono bus 900 MHz, 1.5 MB RAM, GUI client alpha 5.2 has now a rac of 612… about 2500 sec/units. I'm full time on [email protected] now (but the computer is used for other things too)

Will it go even further, we'll see…
MacMusic.Org says "Hi all!" :)
G5 desktop 1.8, 900 MHz frontbus (2003 model)
Latest wisdom file for it on demand, just PM me :)

I havethe dev cli from seti on a 20" iMac and it has been doing fine... sent back 26 and 25 validated. the 26th was b0rked by everyone so I discount that... Getting about 8K secs per block and 2 blocks is nothing to sneeze about.

Rick,

Two questions.

One, SETI worker from Berkeley will update in the near future; see this link:-

http://setiathome.berkeley.edu/sah_plans.php

Will there be a new optimized version from you?


and two, could you clarify for me where exactly to place the big wisdom file, and on what versions of the optimized cc it will work with?

Many Thanks.

K.

You mean the official [email protected] client? Yeah, that should probably work fine (although I haven't tried it myself). There are just some problems with the optimised client that I'm working on.

Damn right.

How soon will depend on when [email protected] switches the main project over to the enhanced client and how long it takes us to port our optimisations across (the code is quite similar so it shouldn't be too difficult).

There are still a few kinks for us to iron out of the current optimised client though.

The more recent work with wisdom files etc. has been entirely done by Alex so I'm still not entirely up to speed on it.

As far as I know, just put the wisdom file in the same directory as the worker (sez ere...). I think it only works on the latest G5 client (i.e. alpha 5.2) but Alex will have to confirm that.

Oh yeah, Alex isn't around because his PowerBook is f---cked so dunno when you can expect some more definite replies from him.

I might as well pop in and answer this question, especially since Rick pointed out my current status...

The bigfft_wisdom file goes in the same directory as [email protected], or whatever exactly I called the cruncher binary. Going along with what I said about the filename, it only work with (read: it's only needed for) G5s running alpha-5.2, since G4s never got a release of alpha-5.2. One note, though: do make sure that bigfft_wisdom doesn't acquire any extraneous file extensions along its journey, since this will cause the cruncher to not be able to find it.

(The answer to the question ends here. From here on, it's more news updates...)

However, when I get my PowerBook back from its repairs (it's already fixed, but it's a long trip for me to retrieve it), I might be pushing out something that will most likely be called alpha-5.3. This might be for both G4 and G5, since I figured out what negated the performance gains of alpha-5.2 on faster G4s. It might also help those of you whose system setups require you to run multiple SETI processes in parallel (*cough*quads*cough*), since one of the tweaks cuts down on how hard the client hits memory for certain parts of computation.

In reality, I think I have the binaries here with me on a Flash drive, but whether or not I release them without having the ability to work on the code depends on how much demand there is to try something that can't be fixed immediately if problems arise. I can provide 2 data points, though (YMMV): it knocks the reference unit time from 39:xx to 36:xx on a 1.8 GHz G5, and from 99:xx to 83:xx (!) on my 1.67 GHz G4 PowerBook.

You could, and there will be no shortage of volunteers to test it out, however you may want to save on effort and wait until the new core client, or worker, is released. The impression I have is that it will be fairly soon, but don't hold me to that.


btw, I'm sure there is a quad out there with your name on it; and Rick as well. Thanks to both of you for your efforts.

The only effort required at this point is to simply upload it to my webspace and make a post to these forums. Yes, I know that SETI Enhanced is coming soon, but it seems like Enhanced has been almost here for quite some time now. Also, the clean codebase that Rick set up for us to work on is something I'd like to stick with as long as possible. If you've looked at the source code I've posted, you might see what I mean.

I'm definately up for testing 5.3 on my g5 and g4's ,

please upload the new client to your space alex,

i agree about the enhanced being forever in the pipeline, thats seti for you

thanks again for your efforts alex, it keeps us obsessed crunchers happy

Alex: I will be happy to test 5.3 on my G4 MDD w/Giga dual 1.33.
May need a refresher(aka help) on the best way to generate a BigWisdom file. I know there have been a few different ways explored to create them. Is there a concensus on THE best way?
Might as well do it right from the start after all.

I'm curious,

Has anyone of you experienced a slight increase in CPU temp/fan speed using the optimised G5-5.2 client...?

I've compared the above client to a G5-alpha 5 SETI client and the standard Einstein client, temperature jumped by an average of 1 - 3°F....

I've posted the binaries and a version of app_info.xml in http://inst.eecs.berkeley.edu/~alexkan/seti/a53/. If you're running the G4 version, edit the app_info.xml file I've included to replace all instances of 'G5' with 'G4'.

I know the packaging sucks, but hey, it's 3 AM right now, and I need to get to sleep. Nicer file packaging to come later.

You'll need the appropriate wisdom files. I can't imagine there's much wisdom floating around for G4s, so if people want to generate some and start posting what they've got, that might be helpful.

Post links to your stats if you get the client working.

Good lord: trying this out now - running.

CPU G5 2.5 dual with 2.5 GB ram.

Block 1 is 10 minutes and 5 seconds in, claims 10 minutes 22 seconds remaining (61%).
Block 2 is 4 minutes and 48 seconds in and claims 9 minutes 17 seconds remaining (58%)

I'll have to generate wisdom files for the G4 to see where we're at with that.

Block 2 is 4 minutes and 48 seconds in and claims 9 minutes 17 seconds remaining (58%)

I'll have to generate wisdom files for the G4 to see where we're at with that.


so thats one person getting the new 5.3 client running, any one else ? i wonder what the difference between the systems are ?

look forward to hearing your results todd

Since so many people have had problems, I've gone ahead and packaged the clients. Try downloading the .tar.gz files that are in the directory now.

If you want to try playing with what you've already downloaded, try Thanar's suggestion of chmoding the application file +x. The file permissions don't really carry over when you're just downloading the file. If you want to do it without having to use Terminal, view the info for that file in the Finder and make sure that you (the user) have permission to execute the file. Such is the problem with not packaging the files more nicely, I suppose.

Todd, can you somehow mark off where the alpha-5.3 results begin in your list of returned results (like the time the first alpha-5.3 result was returned), so I can follow what's going on?

Looks like block one was 39:59, block two was 39:39 and block three is 36:46.
An encouraging trend.

Looking at the previous dozen or so before 5.3 at 100% waiting to upload we have:
42:04, 42:08, 39:43, 38:23, 42:18, 42:31, 38:42, 34:23, 39:44,
38:04, 42:26, 38:38, 38:51.

You see that it all seems to gravitate around 42 minutes, sometimes
below, sometimes above.

For a long time, this machine was generating a ton of blocks right under
2000 seconds. We'll see if we get there this time or if it goes a bit lower.

Stay tuned!

Two more blocks:
37:00 and 36:37

One more thing:
http://setiathome.berkeley.edu/resul...496&offset=620

I can't tell what was processed with 5.2 and and what was 5.3.
Seti is still trying to play catch up and I'm not sure what was
processed with the old client and what with the new but I've
checked activity monitor and we're definetely running 5.3.

And yes, you do need to bring up a terminal window and
perform a chmod +x on the executable to get it to work.

My G4 is sitting downstairs generating a bigfft_wisdom file,
it could take a better part of the evening since it's a 400 mhz
cpu.

More as more becomes.

Todd: I need to run a BigWisdom for my G4. Any recommendations based on how you've been running yours? I don't have another machine to try remote through SSH. If I did it in single user mode however, this would be minimal processes right, no GUI, no user log-in?

If I run in single user mode, any idea "where" the output BIgWisdom file will be generated or how I can find it? Sorry for the NB questions, still learning. Really appreciate your help.

single user should work fine (provided you make the drive writable)

the wisdom file is created in the same directory that the fft_test2 is run from, expect it to take hours and hours for a g4 tho

Yep. I've been running mine since around 5:45 p.m. central daylight time and it's
now 10:47 p.m. and still running - I think it's got one more thing to go and it will
be done in the morning sometime.

Thanks for your kind reply. Could you explain "make the drive writable"? Thanks again!

Darn, my CPU runs hotter with 5.3....

I'm switching back to 5.2.... sigh

How much of a difference is there? Also, what exactly are the negative repercussions with regard to having the CPU run hotter? Personally, I'm just taking it as an indication that the client is getting better and better at maxing out the actual CPU resources, beyond just pegging usage at 100%. Of course, if noise and cooling are a problem, I can see how this would be less than ideal.

Also, any people running alpha-5.3 on quads yet? I want to see if this helps with the bandwidth bottlenecks as much as I would hope it does.

I've compared the above client to a G5-alpha 5 SETI client and the standard Einstein client, temperature jumped by an average of 1 - 3°F....
1-3 °F (½-1½ °C) is a very very small amount and could easily be attributed to changes in the ambient temperature of your environment.

What sort of temperatures are you getting, and why is this a problem?

Faster code will make better use of CPU and memory resources so they will use slightly more power (maybe) and therefore run slightly hotter (maybe). The trade off is that it does this in less time...

That's because I'm running it on an iMac in a tropical country where cooling is a problem.... I don't know about PowerMacs, but on an iMac with a tight enclosure, CPU temp reaches 170°F with 5.3...

Fair enough.

You should probably have a look at the Apple developer notes. I think they specify the operating temperatures for the your system (if you don't already know them).

It doesn't really matter if the system gets hot (apart from annoying fan noise) as long as it stays within spec. If the operating system detects that the system is getting too hot it should shut it down automatically (to prevent possible hardware damage).

I've never heard of this occurring but I guess your circumstances count as exceptional.

in single user mode you cant modify the volume until you run the command:

/sbin/mount -wu /

this will mount the / partition enabling your wisdom file to be written to the drive

while you are there running fsck -fy would be a good idea (which is a disk volume check)

hope this helps

170 degrees isnt too hot for a G5 processor my dual 2.7 runs at 185 degrees 24/7 without any problems.

this is within the operating range of the G5 chip... so if you can stand the fan noise you shouldnt be doing damage to the machine..

the operating system monitors the cpu temperature constantly and will shut down if the temp runs into the danger zone... this is very rare if everything is working fine

saying that there where reports of overheating in early G5 imacs, but if your machine has never shut down due to temperature i doubt if your affected

the hotter the client makes the processor run at the better as far as im concerned. it would suggest that the client is using all functions of the chip in an optimised manner

you may find enabling NAP cools things down a bit (you need to install chud tools for this)

also make sure the hard drive is set to sleep whenver possible and the screen is set to power off after a short time, this will help a little

running boinc from a usb pen drive will enable your hard drive to sleep much more often which will bring the case temp down . hard drives in imacs can add alot of heat to the equation if left spinning all the time

My temperatures are also about the same as they were with 5.2.

Memory controller heatsink is actually substantially lower than usual which
is great. I've seen it as high as 213 degrees fahrenheit with 5.1 and between
last night and this morning with 5.3 (about thirteen hours) maximum was 191.8.

Highest processor temp was 173.6 for processor A, for B 168.6. So this is good.

One issue: the client still labels itself as 5.2 in the blocks sent to Seti.

I see a lot of blocks uploaded in the 1800-2200 seconds range now.
It used to be that was sort of an exception that would happen once in a while.

At one point during the night I had three in a row that were
1929, 1966 and 1979 seconds. And right before that 2221 and 1953 seconds.

With 5.2 it would throw a 1900 second block once in a while but usually 2300-
2500 seconds.

This development is looking good.

Oh - I have my wisdom files up on my webserver:

http://pod.ath.cx/wisdom/

One for the G5 2.5 dual, the other for the G4/400. No results on the G4 yet,
the wisdom file just stopped computing about an hour ago so it's working on
the first block.

I've just started using it on my Quad G5 this morning (currently in the #5 spot in the [email protected] Top Computers Stats list).

I'll let you know how it goes... and if you want to monitor it yourself: Here's my Comp Info on Berkeley's site

UPDATE: So far so good... only one Invalid error and a bunch Validated. Times are a few hundred seconds less per WU so far. As noted above, the Seti client still identifies itself as 5.2 in the results rather than 5.3.

UPDATE2: 12 Hours later and still running fine. Additional notes: Running the Truxoft Calibrating BOINC Manager along with the alpha-5.3 Seti. WUs completing between 1500-1800 or so actual cpu seconds with 4 Seti threads at a time. It was closer to the 2000 range on the previous alpha-5.2. I'm using the wisdom file for Quads already provided elsewhere in this forum thread. All WUs have been valid since last update. The Quad was also used for media encoding and FCPro editing at regular intervals throughout the day.

Thanks, next dumb question: Do I need to un-mount after the file writes?
I take it that since the fft_test2 currently located on my desktop and I will open it from that directory, the output file will show there once I log back into the GUI and my user account?
Should have studied Unix years ago instead of wasting my time w/ Pascal when I was in college Thanks for your help and patience w/ my questions.

Got a wisdom file that I generated for a G4 quicksilver 800 mhz where can I post it.

I have started up the alpha 5.3 version with no problems so far. It started reprocessing a unit that had the G4 alpha5 with no errors when restarting. I'll update you on how it's run throughout the day when I get home from work tonight.

you dont need to unmount just type reboot in single user to restart the mac normaly

yes the wisdom file will be waiting for you on the desktop when you log back in

First block returned from the G4/400 after installing 5.3:
9,100.21 seconds.

Encouraging. I'll keep an eye on it.

Down from the previous blocks:
10,061, then 10,234, then 10,495, and 10,542.

I decided to place the fft_test2 file in Applications, restarted in single user mode, at the root# typed sbin/mount -uw /. No problems. I changed the directory to Applications and typed ls to list contents & sure enough, it showed the fft_test2 file.

From the Applications directory, I typed: open fft_test2 and it gave me this:
INIT_Processeses(), could not establish the default connection to the WindowServer .Abort trap

Just for the heck of it, I also tried sudo open fft_test2 Same message. Any ideas?

navigate to the directory then type ./fft_test2

that should do it
