portofolio

One of the tests within the openMosix Test framework is the 'portfolio' perl program; it simulates a portfolio for various stock compositions for a given period of time. This approach is based on the book ``The intelligent asset allocator'' by William Bernstein and the script was written by Charles-E. Nadeau.

To give you an impression I also ran the application with 4 nodes (similar hardware):

[root@dhcp71 portfolio]# time ./portfolio.pl

started, pid: 25446

Simulation finished

real    4m57.966s
user    11m13.700s
sys     0m44.210s

As you can see, we added 2 nodes and we almost doubled the speed. But that's nothing really new.

oMFS test over ethernet

Another part of the openMosix stress test is the mfstest. This application creates a 10Mb file an copies it back and forth to all nodes. Since oMFS is a network related filesystem this should be a test that would actually show a difference.

[root@dhcp71 mfstest]# time ./mfscopy.sh
