Oracle Solaris Studio 12.2
It's been just over a year since the release of Studio 12 Update 1, today we releasing the first Oracle branded Studio release - [URL="http://www.oracle.com/technetwork/server-storage/solarisstudio/overview/index.html"]Oracle Solaris Studio 12.2[/URL]. For the previous release I wrote a post for the [URL="http://blogs.amd.com/developer/2009/07/17/just-released-sun-studio-12-update-1-featuring-optimizations-for-amd-opterontm-processors/"]AMD site[/URL] looking at the growth in multicore processors. It seemed appropriate to take another look at this.
The graph in the chart below shows the cumulative number of SPECint2006 results broken down by the number of cores for each processor. This data does not represent the number of different types of processor that are available, since the same processor can be used in many different results. It is closer to a snapshot of how the market for multicore processors is growing. Each data point represents a system, so the curve approximates the number of different systems that are being released.
It's perhaps more dramatic to demonstrate the change using a stacked area chart. The chart perhaps overplays the number of single core results, but this is probably fair as "single core" represents pretty much all the results prior to the launch of CPU2006. So what is readily apparent is the rapid decline in the number of single core results, the spread of dual, and then quad core. It's also interesting to note the beginning of a spread of more than quad core chips.
If we look at what is happening with multicore processors in the context of what we are releasing with Solaris Studio, there's a very nice fit of features. We continue to refine our support for [URL="http://www.openmp.org/"]OpenMP[/URL] and automatic parallelisation. We've been providing data race (and deadlock) detection through the [URL="http://docs.sun.com/app/docs/doc/820-0619"]Thread Analyzer[/URL] for a couple of releases. The debugger and the performance analyzer have been fine with threads for a long time. The performance analyzer has the [URL="http://blogs.sun.com/d/entry/viewing_thread_activity_in_the"]time line view[/URL] which is wonderful for examining multithreaded (or multiprocess) applications. In addition to these fundamentals Studio 12.2 introduces a bunch of new features. I discussed some of these when the express release came out:
[LIST] [*]For those who use the IDE, integration of support for the [URL="http://blogs.sun.com/d/entry/runtime_analysis_in_the_solaris"]analysis of the runtime behaviour of applications[/URL] has been very useful. It both provides more information directly back to the developer, and raises awareness of the available tools. [*]Understanding [URL="http://blogs.sun.com/d/entry/calltrees_in_analyzer"]call trees[/URL] is often an important part of interpreting the performance of the application. Being able to drill down the call tree has been a very useful extension to the Performance Analyzer. [*][URL="http://blogs.sun.com/d/entry/checking_for_memory_access_errors"]Memory error checking[/URL] is critical for all applications. The trouble with memory access errors is that, like data races, the "problem" is visible arbitrarily far from the point where the error occurred. [/LIST]
The release of a new version of a product is always an exciting time. It's a culmination of a huge amount of analysis, development, and testing, and it's wonderful to finally see it available for others to use. So [URL="http://www.oracle.com/technetwork/server-storage/solarisstudio/downloads/index.html"]download[/URL] it and let us know what you [URL="http://www.oracle.com/technetwork/server-storage/solarisstudio/community/index-jsp-136224.html"]think[/URL]!
