KSE Progress On FreeBSD SMP Environment

Dan writes "This is a significant milestone to be shared with everyone! Khairil Yusof reports that libkse is now running quite well on his FreeBSD 5.1+ current based SMP system. He has tested a bunch of apps on his system, taking the approach of enabling kse one app at a time. He reports a current uptime of 23hrs with these apps running with libkse.so.1, and basically a usable Gnome 2.2 desktop environment. He says that with recent updates, you can now see the threads with top(8). Kernel Scheduler Entities (KSE), is a kernel-supported threading system similar in design to Scheduler Activations [Anderson, et. al.]. It strikes a balance between user-level (1:N) and kernel-level (1:1) threading models, giving most of the advantages of both, and few of the disadvantages of either."

Testsuit and benchmark by rapiere · 2003-06-23 00:53 · Score: 5, Interesting

KSE seems really an interesting implementation in FreeBSD as well as the process to integrate it in the kernel/userland.

LIBMAP permits to cleanly test it on your system (5.1-RELEASE or -CURRENT) one application at a time (you redefine libraries linking per application). I've tried it with mozilla 1.4b for more than a week now without any trouble.

However I wonder about developper's testsuit and benchmarks in order to give some clues to others about how great KSE is.
