A bit ahead of schedule, the IBM MASS and ATLAS libraries for z/OS are now
available for download as part of the XL C/C++ for z/OS update:

Look for the "XL C/C++ V2R1M1 web deliverable with z13 support for z/OS 2.1
" link. The latest (as I write this) Program Directory is available here
(direct link):

http://publibfp.dhe.ibm.com/epubs/pdf/cbc1z200.pdf

Here are the highlights of this new update:

* Support for the new IBM z13 servers, with ARCH(11) and TUNE(11)
parameters, including support for the Vector Facility for z/Architecture
SIMD instructions.

* As mentioned, IBM MASS and ATLAS libraries.

* Support for inline assembler statements (without requiring Metal C
compilation).

* Support for runtime architecture blocks, so that you create single
programs that have varying execution paths determined at run-time based on
the executing server and its capabilities.

If you don't have a license to the IBM XL C/C++ Compiler for z/OS yet,
"Contact your friendly IBM representative." Those who have licenses for the
Rational Development and Test Environment for z or the IBM PartnerWorld z
Personal Development Tool (zPDT) likely already have a compiler license
(for authorized uses).
