/MP has no effect anymore ?

Hi All,

ICC version I'm using is 13.1.1.171. My project contains /MP switch that makes MSVC compile multiple files in parallel, however, ICC compiles files sequentially regardless the /MP switch (it is documented that ICC is aware of /MP though). Is it a bug or what ?

Thanks in advance.

yes, this is known issue and Intel engineers know about this bug, it has been reported and discussed on this forum already.

The issue with /MP should have been fixed in version : 13.1.1.171

On Linux, -MP has different meaning. You should use below instead:

-multiple-processes[=n]
