which version of compiler I should use

Hello all;
please , can you tell me which version of compiler I should download for my linux 32 bit machine (Its a personal machine not in a cluster or workstation)
thanks in advance

For a single system, you would want the Workstation product, and unless you’re using an older operating system, you should use the most current release.

A complete list of supported operating systems can be found in the PGI FAQs

Thanks!
