Description Thomas Preisler 2007-04-10 00:32:33 UTC 
Originally filed as CR6540763

The IDE provides a wizard for constructing Makefiles.  When the user asks for
"optimization", the IDE provides -xO3, which is a relatively tame optimization
flag.  The IDE should at least provide -fast.  A lot of work goes into the
compiler driver to provide a simple compilation switch that gives good
across-the-board performance.  The rest of the toolset, especially the IDE,
should provide equally good usability/performance.

To create a Makefile in the IDE, choose:

- File -> New File...
- Makefiles -> Simple Makefiles -> Single Executable Makefile

There are many other choices to make, but if one picks:

- Sun Compilers / Solaris
- *.f90
- Optimize the Code

The resulting Makefile uses -xO3.  It should use -fast.

The IDE should offer OpenMP support.  Areas of support include:

*) Makefiles that are built with -xopenmp

*) changing source code syntax highlighting so that OpenMP directives and
pragmas are not highlighted as comments but as special directives

*) facilitating the setting of the number of OpenMP threads
