Message 10750 - Posted: 6 Jun 2007, 20:57:48 UTC

Now and then, I get a computation error on one or more of my projects and the message indicates that there is not enough shared memory to run a particular WU. There is apparently a workaround available that allows an Intel Mac user to use Mac OS to increase the amount of shared memory available to programs. However, this problem only seems to occur in BOINC. Is it posible to change BOINC to accommodate this shortage? It seems that other programs are somehow dealing with it.

Thanks,
Jim

Which BOINC version(s) is this possible in? Or is this a 3rd party program?
Which BOINC version are you using?

Version 5.8.17. It is apparently a quite well known issue.

[Now and then, I get a computation error on one or more of my projects and the message indicates that there is not enough shared memory to run a particular WU.

This is surprising, as BOINC uses only about 2K of shared memory to communicate with each running project application.

Which projects give you this error? Exactly what is the error message you are seeing?

I have no doubt that this works. My question/issue is why is BOINC the only program that seems to have a problem? I NEVER see this from any other application. I will research my records to see if I can determine what apps this comes from. I think it is ABC finder and S@H, but I will monitor it more closely.

The reason you may see this problem with BOINC but not other programs is that BOINC uses a shared memory segment for each project it is running, so when you participate in several projects you can easily reach the maximum limit unless you raise the limit "by hand" by using the instructions mentioned above.

Other programs you may use on a Mac do not make so much use of shared memory, so you are not likely to hit this limit that way.

Just speculation, but I guess most apps that use shared memory only hang onto it for brief periods—or ‘recycle’ it frequently.

Just speculation, but I guess most apps that use shared memory only hang onto it for brief periods—or ‘recycle’ it frequently.

And BOINC is supposed to do the same.

The system can run out of shared memory in two different ways: either by exceeding the total amount of RAM available for shared memory, or by exceeding the number of separate shared memory segments available from the system.

The workaround posted by Zombie67 increases both of these limits, so I can't tell which failure mode is happening from the posts to this thread so far.

Note that the method mentioned in this post is a workaround that does not fix the basic problem with BOINC, if there is one. That is why I would really appreciate more details. If I can determine exactly what is happening, I can try to fix it in BOINC so others won't have this problem.

My guess is that the number of segments is exceeding the limit of 8. BOINC should release each segment whenever a project application is removed from memory.

Unless the computer has 8 processors, there should never be that many BOINC projects running at once. However, if you are attached to a large number of different projects, and have set your preferences to keep applications in memory when suspended / preempted, it might be possible to have a large number of BOINC project applications in memory at once.

It's also possible that some BOINC projects have compound applications which are allocating an additional shared memory segment for their own communications. And of course applications other than BOINC may be using shared memory segments.

So any details you can provide, including the exact error message you are seeing, what projects you are running / have in memory when it occurs, etc. will help solve this for others, even if the workaround has solved it for you. Perhaps you could temporarily set the parameters back to their previous values to reproduce the problem. Or better yet, try setting only the number of segments back to 8 (kern.sysv.shmseg=8) and see if the problem returns.

Thanks in advance for helping us improve the BOINC experience for everyone.

If it is a Mac specific problem (and it clearly is), perhaps asking in the apple support forums would help?

Here's an example system from CPDN :

http://climateapps2.oucs.ox.ac.uk/cpdnboinc/show_host_detail.php?hostid=650288

Note that it's an 8-processor box (one of the Xeon based Mac Pros, presumably), so the limit you mention of 8 will already have been reached. If it swaps between projects (with 'keep in memory') then it would exceed the limit immediately. There appear to be quite a lot of 8-core Mac boxes around now.

<core_client_version>5.8.17</core_client_version>

Error in creating shared memory region!

</stderr_txt>
]]>




I run a dual-core Windows system, and there are invariably more than two Boinc tasks in memory at any moment in time (due to running more than one project) - as we speak there are 5 (3 of which are suspended but in memory).

If we consider a quad-core mac box used for multiple projects, it seems perfectly possible that the limit of 8 in memory at one moment in time may be exceeded. With an octocore box, it seems virtually inevitable.

How many shared memory segments does a compound application such as CPDN use? There's the one for boinc.exe to science app, but the science app is made up of a couple of processes too, so perhaps a second memory segment is taken up there.

Perhaps the Mac variant of the Boinc daemon should try to limit the number of in-memory tasks (i.e., keep swapping between running tasks rather than starting a new task from a project owed time).

Is there any way for the Boinc daemon to ask the O/S how many shared memory segments are unused, and use that to decide whether a new task can be started or not?

Is it at all possible that future versions of Boinc / + science apps (perhaps V6) could share a single segment rather than using one segment per science app? (or would this introduce a common-point-of-failure?)

In the future the number of cores per box will increase further (Intel Shanghai, to be released next year, will mean that twin-socket systems such as the Mac Pro will increase to 16 cores. Ditto with AMD and the Montreal chip, but since they're not used with Mac's Darwin that won't be a problem).

Hi Charlie,

Sorry it took me so long to get back. I have been mercifully away from my computer for a few days.

The last time I saw the message "<core_client_version>5.8.17</core_client_version>
<![CDATA[
<message>
Can't create shared memory: system shmat" was in ABC@Home Beta. I have also seen it in the past with S@H. I have not made the system changes yet, nor have I seen the problem since late May. I have a 4-processor Intel Mac which I keep filled up with BOINC tasks. I do not leave apps in memory. During my last encounter with this message, I probably had 5-7 other programs running.

I am more than happy to help you ferret out this issue. Just let me know what you want me to do. I am somewhat computer literate, but not in your league so you may have to be patient in explaining to me what to do.

Thanks,
Jim

Charlie,

Using BOINC 5.10.7 under OSX 10.4.10, I am now seeing this problem more often. Below is a listing the the messages that occurred leading up to the shared memory error. Only BOINC was running and up to 4 projects were running simultaneously.

As you see, S@H Beta had problems about 3 hours into the run at around 21:04. THe next set of issues occurred about 9 hours later at around 06:28 with S@H and S@H Beta. The next night, which is not copied here, it was RCN with the problems and E@H, so it does not seem to be project specific.

My system settings are the default settings. Let me know what settings you want altered or what debug to turn on.

Thanks,
Jim

My system settings are the default settings. Let me know what settings you want altered or what debug to turn on.

First, please do verify that your preferences are set to not leave applications in memory. Unfortunately, even with this option off, BOINC will still leave applications in memory if they have not checkpointed.

On the basis of these reports, I've made major changes to the way that BOINC handles shared memory unavailability. It will no longer cause a computation error, and when all BOINC's available shared memory segments are in use, it will run only those applications which already have shared memory allocated (such as those left in memory because they haven't checkpointed.)

I expect to release this to alpha testing as version 5.10.10 later tonight. Please get a copy from the "all versions" download page and see if it helps.

Otherwise, you can try increasing the shared memory limits as described by Eric Myers at the URL Zombie67 posted earlier:

I will be on vacation for a week, so I won't see any further postings until after July 8. I hope this helps.

Cheers,
--Charlie

On the basis of these reports, I've made major changes to the way that BOINC handles shared memory unavailability.

I also discovered that BOINC was doing a poor job of cleaning up after itself when it quits, so it sometimes left orphaned shared memory segments in the system. While these did not count against the per-process limit (8 by default on the Mac) it did count against the system-wide limit (32 by default on the Mac.)

So if you quit and restart BOINC a few times, and especially if BOINC crashed a few times, it might be good to restart the computer.

The new version 5.10.10 does a much better job of cleaning up shared memory segments, even when being restarted after a crash. So this should not be a problem with 5.10.10.

Charlie,

New version works great. Absolutely no problems.
