AMD gives profiler to Eclipse community


By Robert Mullins
March 20, 2008 — 
SANTA CLARA — Chipmaker AMD is releasing to the Eclipse community a free plug-in for analyzing the performance of Java code on multicore processors.

CodeSleuth is based on a profiler tool AMD uses internally, called CodeAnalyst Performance Enhancer, to study code written for its own AMD Opteron quad-core processors. AMD announced the contribution Tuesday at EclipseCon 2008.

The CodeSleuth profiler can read the performance counters embedded in the processors to determine how well the code is interacting with the processor. If it takes longer than expected to perform a particular action, or “method,” the code can be modified to improve performance, said Rob Huryn, senior manager of developer outreach for software alliances and solutions at AMD.

CodeSleuth differs from other profilers because it provides more granular information on where to find the problem code, Huryn claimed.

“Let’s say this profiler is telling you that your system is spending 70% to 80% of your time in this [particular] method. If that method has 15 lines of code, that’s great. You know which 15 lines of code to look at. But if it’s 150,000 lines of code [it’s harder]. What CodeAnalyst does is it points at the needle in that haystack,” Huryn explained.

Developers need to first download CodeAnalyst, which is free but not open source, in order to download CodeSleuth, which is free and open source, Huryn explained. Although it works on any processor platform, it includes some features that only work on AMD processors.

The contribution of CodeSleuth to the Eclipse IDE is AMD’s way of helping software developers write applications that maximize the performance of multicore chips, contrary to the conventional wisdom that it’s up to software developers to keep pace with processor advances, he said.

“We’re not going to just [release] 4-, 8-, 16-core processors and then point the finger at the software community and say, ‘You guys aren’t keeping up,’” he noted. “We’re trying to take some of the responsibility. How can we do more things intelligently in hardware to guide software?”
