YAXT

This release contains minor fixes plus a switch to run configure tests with libtool so that users are no longer bothered with details of rpath and library dependencies.

• a minor optimization to prevent unneeded duplication MPI communicators,
• convenience functions to reduce user input at configure time
• further documentation on how to build on Cray XC systems
• various bug-fixes for compiler/MPI fail

The API is unchanged and this version, while a major step in regard to reliability, should be a drop-in replacement for everyone using 0.3.0 at this time.

This release significantly enhances the library:

• Fortran support is finalized, all public functions from the C API have a corresponding routine in the Fortran API.
• Performance has been improved for computations on large distributed objects while decreasing memory requirements at the same time.

• Improved computation of intersections for large index lists.
• Exposes more of the API to Fortran.
• Some performance/memory improvements.

• The Fortran interface and Fortran language tests have been greatly improved.
• Two calls added to determine if the library has been initialized (xt_initialize*d*/xt_finalize*d*).
• XT_INT_MIN and XT_INT_MAX limits added.
• Lots of bug fixes and code cleanup.

A new release has been made available.

Following are the most important changes:

• Every Xt_idxlist object now is given a unique ID to be used e.g. as an O(1) heuristic for equality checks.
• The source now builds with
