properly by allow programs that use shared memory to migrate off the host.

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?

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!
Comment 3 Robert Moss (RETIRED) gentoo-dev 2003-12-14 02:30:29 UTC
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...
Comment 4 Michael Imhof (RETIRED) gentoo-dev 2003-12-27 03:12:38 UTC
Great! I'm going to check in the ebuild now.
Comment 5 Michael Imhof (RETIRED) gentoo-dev 2003-12-27 03:21:09 UTC
Checked it in.
Thanks for your submission.
