New whitepaper: Tuning Parallel Code on Solaris - Lessons Learned from HPC

Most computers today are equipped with multicore processors and manufacturers are increasing core and thread counts, as the most cost effective and energy efficient route to increased processing throughput. However, tuning parallel applications brings with it complex challenges that can only be overcome with increasingly advanced tools and techniques.

The set of tools needed to achieve this goal was expanded continuously in each successive version of the Solaris OS, culminating in Solaris 10 and OpenSolaris with DTrace — arguably the most advanced observability tool available today in any operating environment. Learn by example about the tools available in Solaris and how they can be applied to determine where problems lie with parallel code and then how to figure them out. Download PDF

New Whitepaper: HPC Profiling with Sun Studio Performance Tools

Abstract: In this paper, we describe how to use the Sun Studio Performance Tools to understand the nature and causes of application performance problems. We first explore CPU and memory performance problems for single-threaded applications, giving some simple examples. Then, we discuss multi-threaded performance issues, such as locking and false-sharing of cache lines, in each case showing how the tools can help. We go on to describe OpenMP applications and the support for them in the performance tools. Then we discuss MPI applications, and the techniques used to profile them. Finally, we present our conclusions. Download PDF
