bam (mgcv) not using the specified number of cores
Hi Andrew, Could you provide a bit more information, please. In particular the results of sessionInfo() and the code that caused this weird behaviour (+ an indication of dataset size). best, Simon

I am getting strange behavior when trying to fit models to large datasets using bam. I am working on a 4-core machine, but I think that there may be 2 physical cores that the computer uses as 4 cores in some sense that I don't understand. When I run the bam using makeCluster(3), the model runs on one core. But when I run it on makeCluster(2), top shoes me that three of my cores are taken up to full capacity, and my computer slows down or crashes. How can I get it to truly run on 2 cores? I'm on a thinkpad X230, running ubuntu. Thanks, Andrew
