Can a process run on more than 1 cpu?

[Johan Barelds]

Hi all,

Situation: server with 4 cpu's.
A specific proces uses only 1 cpu for 100%. Is it possible to run this process over more then 1 cpu?

The general answer is no although unless the application is multi-threaded.

I am sure you can, but you will receive no benefit unless there is a lot of work that can be devided amont the CPUS'

For example a large number of calculations that can be split into multiple parts.

As to how to do it, I'd use c language. It has the right fools for splitting up work and dividing it into child processes.

In the situation you've described - no. The application is obviously not multi-threaded and the only way to make it multi-threaded would be to rewrite it.

Hi,

It is not possible to share the load of this process across multiple cpus because it is single threaded. Single-thread is meant literally.

I think if the application is thread capable, it will use multiple cpu's but otherwise not...

untill someone writes a program like Autoport aggregation (available for network cards)!!!!
