PerfSuite 1.0.0 alpha 3 released
- A new Java-based version of the "psprocess" command (the existing Tcl version is still available).
- A new JVMTI-based Java agent called "psjrun" for performance measurement of unmodified Java programs. This is the Java analogue of PerfSuite's "psrun" command.

TAU can now interface with PGI's runtime library and extract performance information associated with kernels that execute on the GPGPUs. TAU tracks the interactions with the GPGPU as seen from the host and generates the performance data. This data includes the name of the routine, file, line number as well as block and grid sizes and individual variable names. This feature works with PGI 8.0.3+ compilers that support the #acc region/end region directives. These source annotations may be placed around loops to automatically generate GPGPU code that executes on CUDA enabled NVidia cards. Users do not need to write any GPGPU specific code explicity. Instead, they use a compiler flag (-ta=nvidia) to generate this code using a special add-on package with the PGI compiler.
This release improves support for Charm++ and NAMD. We have a wiki page that describes how to build and use TAU with NAMD.
