Re: Need application ...

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.
