First, the authors describe basic usage syntax for inline
assembly (inline asm) embedded within C and C++ programs. Then they
explain intermediate concepts, such as addressing modes, the
clobbers list, and branching stanzas, as well as more advanced
topics, such as memory clobbers, the volatile attribute, and locks
are discussed for those who want to use inline asm in multithreaded
applications. See the article here.

Check-out this tutorial to learn how to use the interoperability features of the IBM XL Fortran and the IBM XL C/C++ compiler to integrate Fortran, C and Java source code into an application. The demonstration shows how to call Java source routines from Fortran and vice versa. Interoperability is useful for integrating parts written in different languages into an application. This enables developers to take advantage of language best situated for the job or easily integrate legacy assets into a new application.

This demo explains how to use the MASS high-performance mathematical libraries via the auto-vectorization features supported by XL compilers. The demo is built upon the examples given in a developerWorks article titled “ How to improve the performance of programs calling mathematical functions -- Taking advantage of IBM XL C/C++ or XL Fortran compiler auto-vectorization ”. Please refer to the article for detailed explanations on MASS libraries, auto-vectorization, and the Fortran and C source code.

ATTENTION: this blog post is now old information, kept here only for older service compiler information purposes. A new blog will show the new XLC++ 13.1.2 and future compiler's C++ Standard Compliance Status. C++11 (which was codenamed C++0x until ratification) is the new C++ programming language standard that has just been ratified and published . It supersedes the C++ 2003 (which was a bug fix on the C++ 1998) Standard and is called officially ISO/IEC 14882: 2011 IBM's xlC (C++) compiler has started supporting C++11 since... [More]
C++ 11 is official and published! It is now possible to purchase the new C++ 11 Standard from the INCITS/ANSI website: http://webstore.ansi.org/ RecordDetail.aspx?sku=ISO% 2FIEC+14882%3A2011 or direct from the ISO website: http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=50372 You can still get C++03: http://webstore.ansi.org/ RecordDetail.aspx?sku=INCITS/ ISO/IEC%2014882-2003 If you find the price a bit high, it is also possible to wait a bit until the British Standard Institute publish a hard-copy book...

After almost two years of work, OpenMP 3.1 has been released. Here is the announcement on it and the new specification in pdf online. As I mentioned in the previous note on the public comment draft , and in this trip report and Steven Perron's posting about the new content, 3.1 offers something for everyone. The main purpose of OpenMP 3.1 was to redefine and extend existing specification, and maintain backward compatibility. This was also a bug-fix release in that it clarified a number of examples in OpenMP 3.0 and fixed about 20 minor... [More]
This Standard meeting is earlier then the usual C++ Standard meeting to accommodate the period of time after the approval of the C++0x draft when National Body balloting has to be done to approve the draft and ratify it. The new C++0x Standard has been ratified and will be called C++11. As an additional note, the C standard is also undergoing ratification vote and will also likely be approved. So there is now a quiet period when we cannot issue new papers. As it happens, the defect reports for core language and library are also issued as... [More]
