Acumem has launched ThreadSpotter 2010, an updated version of a tool that "suggests" ways to improve performance by reducing cache pollution. Applications often fill the caches with data that is never reused before being evicted, and that therefore does not benefit from caching. ThreadSpotter finds the locations in the code responsible for this cache pollution and suggests ways to avoid allocating cache space for the data. This is designed to improve performance by leaving more cache space for other data structures that do benefit from caching, and for other threads and applications that share the caches in multicore systems.
ThreadSpotter 2010 also works with OpenMP and can analyze MPI applications. Release 2010 also brings a speed up of the sampling of multithreaded applications. Acumem claims speed ups of heavily multithreaded applications by more than 10 times. This furthers improves the usability of the tool, especially when working with heavily threaded applications.
