Dear Laurent,

An R proces uses only one core. It is possible to use multiple cores. Have a look at he Hig-Performance and Parallel Computing task view (http://cran.freestatistics.org/web/views/HighPerformanceComputing.html)

Best regards,

Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

Onderwerp: [R] CPU usage while running R code

I am currently running an R program on a computer with 16 Gb memory (Windows7, 64 bit). When I look at the task manager, I see that only 4 out of the 8 CPUs are being used. Is this due to some missing in the R code, or should I change something to the settings of the computer?
