      Release Notes: Initial support for Intel Sandy Bridge (Core) in likwid-perfctr. A new application, likwid-perfscope, as a frontend to the timeline mode of likwid-perfctr (experimental). Initial support for OpenMPI in likwid-mpirun. Improvements in likwid-msrD. A native Fortran 90 interface for the Marker API. A complete rewrite of the marker API. Simplified usage. Allows inclusive and overlapping regions. A new output filter subsystem. Allows you to define your own output file formats and filters. By default, comes with CSV and XML formats.

          Release Notes: Performance groups were improved in likwid-perfctr (NUMA group for AMD K10). The new likwid-mpirun script was added, which is an mpirun wrapper to enable pinning for MPI and MPI/OpenMP hybrid applications. likwid-perfctr supports output in files with placeholders for MPI parallel applications. Thread domain M (Memory) was added for NUMA domains. Documentation in the wiki and man pages was improved. Pin functionality was integrated for likwid-perfctr. likwid-msrD was added, which is an msr daemon to enable secure access to msr registers in security sensitive environments. Many bug fixes and small improvements were made.

            Release Notes: Full support for AMD Magny Cours was added. The core events of Intel Nehalem EX are now supported. likwid-pin can also use logical pinning now. A daemon mode was added for likwid-perfctr, supporting very lightweight monitoring. This daemon can also be used to generate timeline graphs for a specific application.

              Release Notes: The likwid-bench application was added, allowing rapid multithreaded prototyping of low level benchmarks. Logical pinning on the node/socket level was added in likwid-pin. NUMA topology support was added in likwid-topology. likwid-pin can set NUMA mempolicy to interleave. Event sets for likwid-perfCtr are configurable and extensible with simple text files. Extensive help for group configurations is available from the command line. A flag for silent execution in likwid-pin was added. Statistical output (Sum, Max, Min, Avg) is produced for threaded measurements in likwid-perfCtr. Execution was made faster for likwid-topology and all print switches.

                Release Notes: This is a patch release. It fixes a bug that occurred if you were using likwid-perfCtr with OpenMP using the marker API and pinning the threads with likwid-pin.
