RE: Need application ...

Joel

I think Blast would be a good application to benchmark your solution with.
Also, I am very interested in having a look at your solution, it sounds very
interesting, indeed. Got a link to it somewhere?

Thanks for the reply Bruce.

I am looking for an application that performs fairly poorly on an openMosix
cluster due to the fact that it migrates quite often. I was hoping that
"make -j" suggestion would generate many (mostly
unnecessary) short-lived migrations.

I have implemented a low-level single-segment networking protocol that can
be used to replace TCP on a local cluster. I have ported openMosix to use my
protocol instead of TCP to perform migrations. I wish to compare
openMosix-using-my-protocol to openMosix-using-TCP.  
The only possible advantage I might have is due the amount of time to
migrate a process. If I compare the two using a CPU-bound job, then the
saved time in migration will be mostly hidden by the time spent on on the
CPU.

I wanted a real-world application if at all possible, but in absence of that
I will fall back to a much more contrived application. I have timings based
on individual migrations (time to migrate a single process of a certain
size). I am looking for an application where using my protocol shows an
obvious overall wall-clock time improvement.
