article de présentation sur
d'un cluster openMosix
|This paper describes the use of two
complementary technologies from two different fields:
- OpenMosix - a "clustering" technology which makes it possible to set up a group of PCs to perform compute-intensive operations, so that they act rather like a single multiprocessor SMP system
- LTSP - a "terminal server" technology which facilitates very simple management of large groups of PCs
Each of these technologies is aimed at a solving a different problem and can of course be used independently: OpenMosix builds up computing power by sharing the processors of many machines on a network so that the workload is balanced across the cluster. LTSP makes it easy to roll out diskless workstations (or"thin clients") with minimal admin overhead.
|However, put the two
together with a mixture of other Unix services (like ftp, dhcp, nfs,
xdm) and you get a hardware and software platform which can not only
perform compute-intensive work but is also easy to roll out and change. With no more
than a simple Etherboot floppy disk or a PXE remote boot you can add
PCs at will to the system and increase the overall computing power.
Putting OpenMosix and LTSP together gives an elegant solution which is both extremely effective, simple to manage, and very cost effective. It is the ideal solution to the computing needs of many laboratories."
