I don't want to appear stupid, but can you tell me how to check?

You don't. I know next to nothing about Linux, hence the openess (stupidity) of the question :)
My hope was that top or some other similar utility would give you an overview of the system by cpu. If you set the program running on a long file and the overall cpu load seems split fairly evenly between the two cpus, with an otherwise mostly quiessent machine, then it would be a reasonable indication that the the two threads are being dispatched to both processors.
On Win32, there is a system call GetProcessAffinityMask() which I can call to to check which cpus the task is allowed to run on, and an equivalent call to set that. There is probably something equivalent in Linux, but I haven't a clue where to start looking for it:(

Hopefully, someone else will shed a little light.
The Machine has Hyperthreading on as well I think, as cat /proc/cpuinfo shows 4 CPUs, instead of 2.
Thanks.
