Compilers and Libraries
To compile a C code using MPI libraries:
Intel compilers ARE available (version 8.1)
Compilers are installed ONLY on the development node.
GNU compilers, gcc, g77, and g++
For help type: man g77
Use optimization flags -O or -O2 for production jobs g77 -O program.f -o program.x
To compile a fortran code using mpi libraries:
- Make sure that /opt/mpich/gnu/bin is in your PATH
- For csh or tcsh shells (in .tcshrc .cshrc or .login):
set path = ($path /opt/mpich/gnu/bin)
- For bash shell (in .bashrc):
PATH1=/opt/mpich/gnu/bin PATH=$PATH:$PATH1
- SSH to the development node from lakemead ssh development
- use the wrapper (script) mpif77 mpif77 -o my-mpi.x my-mpi.f
- connect to the development node ssh development
- Use the wrapper (script) for mpicc mpicc -o my-mpi.x my-mpi.c
- To compile a Fortran90 code: ifort -fast -o my-code.x mycode.f90
- the -fast option sets optimization level and options to -O3 -ipo -static which may improve run-time performance
- To compile a C (or C++) code using the Intel compilers, icc -o fast -o my-c.x mycode.c
- see man pages for ifort and icc for more options
