I can no longer run CM3 Models. They error out immediatly with these messages:

Previously had no problems, Tried restarting Boinc manager,Reset CPDN Project, Rolled back to Boinc 5.10.45. All with no luck
SM3 Models run fine. Any Suggestions ?????

P.S. There is a corresponding .zip file present in the data directory, just without _1 - _7

Your recent tasks are all generating Insufficient Memory/Stack Space Available! errors (e.g. 8139263, click on the \'+\' by stderr out). Instructions to fix the Mac shared memory problem are available here. It\'s possible that the problem is with shmseg (maximum number of shared memory segments per user) as v6 applications require an additional shared memory segment for the graphics (which is now run as a separate a program).

You might like to warn your team mates as some of them seem to have hit the same problem.

P.S. There is a corresponding .zip file present in the data directory, just without _1 - _7

That\'s the model parameters file downloaded from the server.

Please, someone help !!

I\'m not a Mac guy, but in the example on the help webpage that Thyme linked to, he quadrupled the amount of shared memory segments. To do that he multiplied everything that was in default, except the kern.sysv.shmmin, by 4. So if you double one of the parameters, maybe it would be good to try to double all the others as well, except kern.sysv.shmmin?

Just a shot in the dark.

Is there something like \"ulimit\" on Darwin?

If so, try to set \"ulimit unlimited\" before you start BOINC.


(maybe you could post the current limits too, i.e. before you\'ve set \"unlimited\")

p.s.: ulimit without options queries or sets only the disk file size, you need to specify \"-s\", \"-d\" or \"-l\" or so (memory related), depending on the options Darwin offers.

p.p.s.: I found the manual entry for \"ulimit\", it\'s a shell builtin (sh, not csh). So (for example) \"ulimit -a\" can show all limits.

I\'m starting to think the shared memory segments aren\'t the problem.
I have the quadrupled settings which are more than adequate.
CSM3\'s used to run fine when they started like this \"hadcm3istd....\"
Now they start like this \"hadcm3ivolc...\".
These are different and failing. Nothing else on my end has changed.
If anyone is running these models successfully, please let me know what you did.

---

I see over on the main boards (which I can\'t log into and post for some reason)
They are saying the same thing about memory segments. I have the same values
as the example and it still crashes. How high dare I up these settings ???

---

The discussion board requires a separate signup, it has no access to the BOINC signup data. The signup link is on top of the page there (\"Register\").

Have you tried this \"ulimit -a\" from bash or sh command line (using the user ID that runs BOINC)? What does it say?


While a solution hasn\'t been found yet, you could choose a different model type here, just uncheck the checkbox near \"Application UK Met Office HADCM3\"

Here\'s my current Ulimit results.

BdyGlv-Pro8:~ Ed$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) 6144
file size (blocks, -f) unlimited

I\'m not familiar with Mac and I have no idea how much of which ressource those volcanic models need - but from the error message, the next thing to try would be

ulimit -s 16384
and/or
ulimit -d 16384

in the startup settings (.profile ?) of the user that runs the BOINC client

(sorry, it\'s all a bit experimental as long as no Mac people jump in)

I downloaded to many SM3 wu\'s to get more work right now.
Still waiting to try the Ulimit changes.

The register process is broken on the other boards, and the
moderators won\'t respond to my requests for help.

Can someone try getting this thread going over there to try
and stir up some other mac users, or project people?
The stated fix for this problem isn\'t working. The app is clearly
broken and no one seems to care..... Thanks

Hi BdyGlv

I (and I expect several other CPDN moderators) have been following this thread. I haven\'t responded and tried to help because I know nothing about Macs. Unfortunately I don\'t think any of the CPDN mods are Mac specialists.

You must have reached your daily model download quota which means you\'ll have to wait until midnight (your time, I think) to get a new quota. See what happens when you try Ananas\'s suggestion about the ulimit.

Which other forum are you referring to? I don\'t think you mean the CPDN independent forum. Even if you\'re already registered on it, don\'t start a new thread there because the same people would probably be available to help here as there. It\'s best to keep the whole discussion in one place.

Did you mean you couldn\'t register on the Boinc_dev forum?

Cpdn news

Just a suggestion so that if the ulimit tactic isn\'t successful you don\'t use up your entire task quota for Sunday at once in an orgy of failures.

You must now have no running CPDN models. Your daily quota is one task per core and your computer has 8 cores. You could temporarily limit the number of new model downloads to 2. That should be enough to see whether the ulimit idea works. If it doesn\'t work you\'d still be able to try 6 more model downloads on Sunday.

Boinc Manager > Advanced menu > Preferences > Processor usage tab > On multiprocessor systems use at most > edit the number (which probably says 7 or 8) to 2 > Click OK > Close that window.

If Ananas thinks I\'ve made a bad suggestion I\'m sure he\'ll tell us!

Cpdn news

This is the error message I get when trying to register
at the CPDN independent forum. I\'ve tried a couple of my e-mail address,
and even tried using internet explorer on a pc at work in case it didn\'t like Safari.
(Mac\'s browser)

Could not find email template file :: textual_confirmation

DEBUG MODE

Line : 111
File : emailer.php


Also I don\'t know how to make the Ulimit change permenant.
When i to it from a terminal window, it reverts back to default
when i close the shell. Unix is not my strong suit. Someone else better try this one.
Thanks again .... Ed

---

Try registering again on the independent forum. I\'ve just registered there using a different name and it worked. I created a second new account using Safari and it also worked. You won\'t see my new accounts in the memberlist though because I\'ve cancelled them.

Cpdn news

I\'m still getting that same error message.
I\'ve used my yahoo and comcast email address.
I can\'t figure out what i\'m doing wrong.
It\'s just not my day....

Make sure you give the correct answer to the question under the confirmation code. I just tested and got the same error when I gave the wrong answer or left the box empty.

If it works similar to Unix, there should be a file with the name \".profile\" (without the quotes, but including the starting period) in the home directory of the user. This file usually contains environment and shell settings that kick in everytime you start a shell.

The leading period might make that file invisible in your GUI but you can see it with the \"a\" option of the \"ls\" command (like \"ls -la\")

But it might work different on a Mac.


There are Mac-specific BOINC teams btw., one that comes to my mind would be MacNN, maybe it would be a good idea to join their forum. I guess they will do better than us \"mac-illiterate\" moderators ;-)

edit : I found several more Mac BOINC groups using BOINCstats\' team search

Here is one more host that shows the same error message, it is now running 4 HadSM3 models, obviously the problem is specific for those HadCM3volc models.


p.s.: I did some more searching and found much higher tweaking values for kern.sysv.shmall, some even recommend 65536 there


One more idea (just in case ...) - did you reboot your machine after changing those kernel parameters? It requires a reboot before the new values can take effect.

Finally got another CM3 to try out, and it still crashes.
Yes did a reboot after editing sysctl, here\'s my current values.
kern.sysv.shmall: 65536
kern.sysv.shmseg: 32
kern.sysv.shmmni: 128
kern.sysv.shmmin: 1
kern.sysv.shmmax: 16777216
