Iceberg reaches end-of-life on 30th November 2020. If you are running jobs on Iceberg then you need to take urgent action to ensure that your jobs/scripts will run on ShARC or Bessemer. If you have never used ShARC or Bessemer then now is the time to test your scripts. Not all software on Iceberg is available on ShARC/Bessemer.
The Intel compilers help create C, C++ and Fortran applications that can take full advantage of the advanced hardware capabilities available in Intel processors and co-processors. They also simplify that development by providing high level parallel models and built-in features like explicit vectorization and optimization reports.
Several versions of the Intel compilers were installed on this cluster as part of Intel Parallel Studio but can be used with or without the other Parallel Studio components.
After connecting to iceberg (see Establishing a SSH connection), start an interactive session with
qrsh command. To make one of the versions of the Intel
compilers available, run one of the following module commands
module load compilers/intel/17.0.0 module load compilers/intel/15.0.3 module load compilers/intel/14.0 module load compilers/intel/12.1.15 module load compilers/intel/11.0
To compile the C hello world example into an executable called
hello using the Intel C compiler:
icc hello.c -o hello
To compile the C++ hello world example into an executable called
hello using the Intel C++ compiler:
icpc hello.cpp -o hello
To compile the Fortran hello world example into an executable called
hello using the Intel Fortran compiler:
ifort hello.f90 -o hello
Once you have loaded the module on Iceberg,
man pages are available for Intel compiler products
man ifort man icc
