Putting -lm Before User Objects/Libraries on Link Line Can Impact Performance
Recommended linking model:
icc/icpc/ifort [user objs] [user libs] [sys libs]
Using -lm (the GNU math library) prior to user-created objects or libraries causes the GNU libm to be used instead of the Intel math library, impacting performance. Author: Brandon Hewitt (Intel) Type: Performance and Optimization |
