Composer XE 2013 SP1 Update2 is very slower

Qimiao_L_ · ‎04-03-2014

Hi,

I updated the Intel Fortran Compiler to SP1 update 2 (SP1.2.176) recently. I tried to compile my code using this new update. Compared with the previous compiler (XE 2013 Update 5 - 2013.5.198), it was found that the new update took about two time longer to compile the same code and generated the executable which is also about two times larger than the executable generated by using the previous version. The executable also runs slightly slower than before. Any idea or any settings I should change to use the new compiler?

That's not expected - would you be willing to share your application with us? You can do it through Intel Premier Support.

Thanks for reply. My code is quite big. We cannot share the code due to the copyright. But I will find the more information about the compilation speed. It is really much slower than the previous version. Probablly I need to do this investigation throug Intel Premier Support.
