I'm currently evaluating Intel compiler (V 7.0 Bld 20021021Z) to be used with a large simulation code developed at SKF. RedHat 7.2 and glibc-2.2.5-42 running on dual-proc Athlon MP 1.2G is used.
For some files (major part of the source) icpc takes much longer than g++ (4 minutes instead of 7 seconds).
The options used: icpc -g -tpp6 -I<...> -c<..>
The compiler generates a list of warnings and then freezes with mcpcom taking 100% CPU time.
Have someone seen such behaviour? Are there any guidelines on searching for the problem? Is it possible to detect the stage of the compiler that takes so long time (e.g., produce a log)?
icpc on Linux compile time MUCH longer than g++
