DragonFly users List (threaded) for 2005-03
Other Technology For Review
DIsparate/complementary techniques for handling some of the challenges
DragonFlyBSD addresses w/r SMP and other distributed resources may be
worth a read:
1) Xen Virtual Machine Monitor, primarily Linux-centric, but on x86
PC-grade platforms, not mainframe, and seeking transparent SMP scaling.
DragonFly may make a more suitable candidate than Linux.
- also covers modification of subordinate or 'guest' OS' to live
without direct access
to x86 'Ring 0'.
Related research of possible interest:
'Live' migration of Virtual Machines with running processes:
Safe sharing of physical hardware devices:
2) A light-weight and highly deterministic scheduling method - perhaps of
interest as SMP becomes more affordable, dual-core and 'Cell' processors
arrive in numbers:
XOberon 'Hard Real Time' system for (primarily) machine tool and
Appears dormant, still has some noteworthy features, w/r efficient
shared resource control.
At present/future clock and bus rates, using near-real-time tools at the
base of kernel may ease
uncertainties of resource and communications management at higher levels.
Recommending reading for comparison, not adoption...
these are very different from whereDragonFly is / can be expected to be.
