Concurrency

[hedge2211]

I have just read on a website that if you set the concurrency to shell it ubuntu will work better with dual core processors, as all my computers are dual core I was considering doing it. However, i was wondering what concurrency was and how it made ubuntu work better with dual core processors.

Thanks

If you are compiling a kernel you can use the -j option to increase the number of parallel processes and hence which will make the compile faster on a multi-core machine. Concurrency is running processes parallel - Ubuntu installs the SMP kernel by default. Install htop and you can see load on individual cores. If, for instance, you are running a rendering farm, its good to make sure that different parts of the computation can be farmed out to individual cores and not block on missing pieces.

thanks miegiel, I learn something new everyday.
