B.4 Sun Studio 10 Fortran Release:

• Compiling for AMD-64 Processors

  This release introduces -xarch=amd64 and -xtarget=opteron for compiling applications to run on 64-bit x86 platforms.

• File sharing between big-endian and little-endian platforms

  The new compiler flag -xfilebyteorder provides cross-platform support of binary I/O files.

• OpenMP available on Solaris OS x86 platforms

  With this release of Sun Studio, the OpenMP API for shared-memory parallelism is available on Solaris x86 platforms as well as Solaris SPARC platforms. The same functionality is now enabled on both platforms.

• OpenMP option -openmp=stubs no longer supported

  An OpenMP "stubs" library is provided for user’s convenience. To compile an OpenMP program that calls OpenMP library functions but ignores the OpenMP pragmas, compile the program with the -openmp option and link the object files with the libompstubs.a library. For example: % f95 omp_ignore.c -lompstubs

  Linking with both libompstubs.a and the OpenMP runtime library libmtsk.so is unsupported and may result in unexpected behavior.
