Compiling on the Intel machines Command: ifort

On EM64 systems, use ifort32 or ifort64 for 32-bit or 64-bit memory addresses
See online documentation

Recommended options:

-O2 -xW -tpp7
Example:

ifort -O2 -xW -tpp7 -132 -o file.x file.f -llapack -lblas -larpack

Useful debugging options:

-C -d0

Turns on many checks (array bounds checking for one) and reports the results (see documentation for more info)

See documentation ...

Common libraries:

arpack

diagonalize large, sparse matrices

mkl_lapack

contains lapack and blas among other things

mkl_p4, pthread

libraries for Pentium 4 architecture

Convenient use:

ifc -O2 -xW -tpp7 -132 $1 $2 $3 -lmkl_lapack -lmkl_p4 -lpthread -larpack

Remember to chmod +x this file and add bin to your path, then the compile command is simply

if90 -o file.x file.f

I have found it convenient to make a small script called if90 in a bin subdirectory of my home directory with the following line:

Troubleshooting:
source /etc/tcshrc
endif

If you use bashrc, put the following lines in your .bashrc file instead:

if [ -f /etc/profile ]; then
. /etc/profile
fi

If you have errors that say a library cannot be found, then make sure you have the following lines in your .tcshrc or .cshrc file in your home directory (if you use tcsh):

if ( -r /etc/tcshrc ) then
