Interesting new book on OpenMP available. I've worked with both Ruud and Gabriele. I regularly see Ruud when he makes his stateside trips, and Gabriele used to work in the same group as I do before she moved from Sun. I've recently had a number of entertaining conversations with Ruud comparing the writing and publishing processes that we've been working through.

Hit a problem trying to build a C++ application which required -library=stlport4 under ClusterTools 7. Unfortunately they don't currently mix.
Found a page of links to useful resources about multi-threading on the developer portal.

A couple of folks requested that I post the table of contents for my book. This is the draft TOC, not the finished product. I assume that there will be a good correspondence, but the final version should definitely look neater.

I've previously written up a short entry on using the UltraSPARC T1 performance counters to determine what the processor is doing and where effort might be spent in improving performance. I've just completed a follow up article for the developer portal which discusses this concept in more depth, and covers both the UltraSPARC T1 and the UltraSPARC T2.A quick refresher here is that it's simple to calculate the utilisation of the processor. They have a fixed maximum number of...

I'm thrilled to see that my book is being listed for pre-order on Amazon in the US. It seems to take about a month for it to travel the Atlantic to Amazon UK.

Just been looking at the dwarf debug format. In Sun Studio 12, all the compilers switched to using this format over the older stabs format. Chris Quenelle has put a useful guide to debug information up on the Sun Wiki. The dwarf format overview document is probably the easiest to read, the version 3 specification document is more detailed. The tool to extract the dwarf information from an object file is dwarfdump. For example the -l flag will extract line number info.

The documentation for the Sun Studio 12 version of the Performance Analyzer has gone live. The Sun Studio 12 docs collection is also available.

My (brief) article on the Sun Memory Error Discovery Tool (aka discover) has gone live on the developer portal. The tool is designed to find memory access errors. It instruments the code and checks each memory access to see if it is valid. It can detect things like access to uninitialised memory, or accesses past the end of arrays. These can be really hard to find by inspecting the source, and even from core dumps - the symptoms of the problem often occur long after the...
