Subject: Number of Cores limited to two in CRAN

Hi,
I am developing a package where I would like to utilize multiple cores for parallel computing.  However, I get an error message when I run R CMD check --as-cran.

I read that CRAN limits the number of cores to 2.  Is this correct? Is there any way to overcome this limitation?

Thank you,
Ravi
