Bug 32312 – Need Migshm support with OpenMosix kernel sources

• Status: RESOLVED FIXED

[Description Anthony Blair 2003-10-30 00:00:38 UTC]

MigShm allows OpenMosix to "come to life" and actually be able to balance load
properly by allow programs that use shared memory to migrate off the host.

Reproducible: Always
Steps to Reproduce:
1.
2.

Any update on this?

It seems quite easy to do. I might have a go at writing an ebuild for this later. The necessary steps are quite well documented. Although Migshm is quite beta-ish, it appears remarkably stable. As a pleasant side effect, this may fix the random segfaulting which occurs when python processes start migrating (for example, anything portage-related...) so this could well *increase* the stability of the openMosix sources, despite being a beta patch.

Does anyone have any information on Migshm and python?

Created attachment 22146 [details]
openMosix sources with migshm patch

This ebuild is for the openMosix sources with the migshm patch enabled. The
migshm patch isn't yet available for the 2.4.22-2 kernel and patchset, so this
is the latest available.

Let me know how you get on if you try this!

WORKSFORME. Using the 1.4 patch on the 2.4.21-1 sources on 3 different computers. Load balancing is somewhat improved. I can even get Mozilla to build...

Great! I'm going to check in the ebuild now.

Checked it in.
Thanks for your submission.
