Originally posted by: Jinsong JI Want to maximize your IBM POWER 8 hardware investment? You will need the latest XL C/C++ V13.1.1 compiler to fully exploit the POWER 8 hardware capabilities and take advantage of the compiler's industry-leading advanced optimization technology. This demo...
Originally posted by: llindsay On December 12, 2014, IBM will be releasing a new XL C/C++ compiler to support application development targeting the little endian Linux distributions running on IBM Power Systems with POWER8 processor and architecture. A key strength of the IBM XL compilers...
Originally posted by: melaniejs Computer architectures designed with high-performance microprocessors are reshaping the IT landscape. Today's software developers must deliver products and services faster with higher quality and performance to stay competitive, but in an environment with...
Originally posted by: melaniejs Did you know that the compiler you use can impact whether or not you achieve optimal performance from all parts of your systems. Organizations often overlook the importance of compilers, often running new high-powered servers with outdated compilers...
Originally posted by: Anh Tuyen Tran Programmers put effort into optimizing their applications for performance. Still, performance gain could also be achieved by simply switching to a newer version of IBM compiler. Although improvement might vary depending on the design and...

Originally posted by: dorra When the compiler knows that an array occupies a contiguous block of memory, it can perform optimizations based on memory layout. Explicit shape arrays, assumed-size arrays and allocatable arrays occupy contiguous blocks of memory. For array pointers and assumed...
Originally posted by: Rafik Zurob Input / Output (I/O) performance can be a significant factor in overall program performance. The way you write I/O statements can make a big difference. Consider the following example: subroutine sub(x, n) real x(n) do i = 1, n, 2 ...
Originally posted by: PhilipLuk Did you know that COBOL for AIX, V4.1 contains a new compiler option which lets you selectively target code generation of your applications to exploit POWER7 systems architecture? Imagine you could boost the performance of your existing hardware assets just...
