Cool Tools: Using SHADE to Trace Program Execution by Darryl Gove
The SHADE library is an emulator for SPARC hardware. The particular advantage of using SHADE is that it is possible to write an analysis tool which gathers information from the application being emulated. The SHADE library comes with some example analysis tools which track things like the number of instructions executed or the frequency that each type of instruction is executed. A more advanced analysis tool might look at cache misses that the application encounters for a given cache structure.   »  Read more

Selecting Representative Training Workloads for Profile Feedback Through Coverage and Branch Analysis by Darryl Gove
Profile feedback is an optimisation technique that uses a short training run of the application to provide the compiler with more detailed information about the runtime behaviour of the program. This information enables the compiler to make better optimisation decisions. For example, which routines are appropriate to inline, or which branches are the frequently taken path. This paper presents two ways of viewing the correspondence between the behaviour of the training and reference workloads. The methods presented here are necessary conditions for the training workload to be representative of the reference workload.   »  Read more

New Article: The Challenge of Race Conditions in Parallel Programming
This article discusses general and data race condition that arise in parallel programming. While data race condition problems are common and easy to fix, harder to avoid general race problems can also occur. A race condition could be the symptom of deeper design problems. A simple parallel partitioning example illustrates these various race condition issues and how to avoid them.

New Article: Building Enterprise Applications with Sun Studio Profile Feedback
Large, CPU intensive applications may perform better when built with profile feedback. Profile feedback optimization requires the application to be built twice, once to collect the profile data, and again to make use of the profile to generate optimal code. This requirement may keep some software vendors from building their applications with profile feedback. However it is possible to use old profiles to minimize the overhead of profile feedback builds in a development environment. This article introduces all the stages of profile feedback with examples, and offers some tips for making profile feedback builds.    ?  Read more

New Article: Performance Analysis Made Simple Using SPOT
An application's performance depends on a combination of hardware and software factors. There are a number of tools that can be used to extract information or collect this kind of information, but knowing which tools to pick can be tricky. This paper introduces a new tool that aims to simplify the process of performance analysis. Called the Simple Performance Optimisation Tool, SPOT is an add-on package to Sun Studio 11 for UltraSPARC based systems. Spot is part of the Cool Tools project.    ?  Read more

New Article: Using VIS Instructions To Speed Up Applications
The advantage of using VIS instructions is that an operation can be applied to different items of data in parallel; meaning that it takes the same time to compute eight 1 byte results as it does to calculate one 8-byte results. In theory this means that code that uses VIS instructions can be many times faster than code without them.   ?  Read more
