Better Software For HPC through Code Modernization

Vectorization and threading are critical to using such innovative hardware product such as the Intel Xeon Phi processor. Using tools early in the design and development processor that identify where vectorization can be used or improved will lead to increased performance of the overall application. Modern tools can be used to determine what might be blocking compiler vectorization and the potential gain from the work involved.

Using Vectors on Intel Xeon Phi

The use of vector instructions can speed up applications tremendously when used correctly. The benefit is that much more work can be done in a clock cycle than by performing the operation one at a time. The Intel Xeon Phi coprocessor was designed with strong support for vector level parallelism. “When these techniques are used either individually or in combination in different areas of the application, the performance will surely be increased, in many cases without a lot of effort.”

Call for Papers: HiPEAC 2016 in Prague

The HiPEAC 2016 Conference has issued its Call for Papers. HiPEAC is the European Network of Excellence on High Performance and Embedded Architecture and Compilation.

Free PGI Comes to OS X

This week PGI announced that Free PGI is now available for Macs running OS X. The package includes the PGI high-performance parallel C99 and Fortran 2003 compilers and parallel debugger for 64-bit and 32-bit Intel processor-based Macs.
