How can I generate multi-core load on Stata / MP?

I am working on monitoring CPU and memory usage of Stata / MP (multi-core version of Stata / SE), but I am not a Stata programmer (more of a Perl guy).

Can someone post some code that uses a public dataset to create enough load on Stata / MP, so that the four processor cores are used (or even exceeded) for several minutes or so?

If you can provide me with a .do file and a .dta file (or something else that I might need for this), I think I can take it from there. Thanks in advance!

This should do it:

sysuse auto expand 10000 bootstrap: logistic foreign price-gear_ratio

This answer is based on an earlier answer, but I added a few comments, some tweaking and an additional bootstrap command that creates less load. You can put this in a file called "load.do" and execute it in Stata using File -> Do. Click the Break button to stop execution.

Please feel free to merge this into an earlier answer if this is more appropriate.
