Optimize your Software It is a simple step to speed up your software. No source code changes are required. Lockless MPI seemlessly replaces your system MPI implementation, and you reap the performance benefits. Lockless MPI Released Version 1.2 of the Lockless MPI has just been released. It is optimized for modern 64bit multicore systems, and supports programs running on Linux. There are bindings

C++ memory management C++ is the world of do-it-yourself memory management. When discussing programming with someone, as I reach the point where I tell that I mainly work with C++ the first thing I hear is “Oh… But you have to deallocate memory yourself… That’s so cumbersome and obsolete!” Although I don’t have to wrestle with news and deletes anymore, I find this remark pretty interesting. It’s t

If you want an explanation of the difference between the Packetised and Memory Mapped benchmarks, please see the Tn homepage (but basically, the Packetised involves performing a lot more memory ops in a more loaded multithreaded environment). As you can see above, the benefits of nedmalloc translate into real world code with more than a 50% speed increase over the default win32 allocator. The Tn s

This is the home of the Streamflow project, a scalable memory allocator for multithreaded applications. Source Code The current version has been developed for and tested on Linux, on x86, x86-64, ppc64 and ia64 platforms. http://github.com/scotts/streamflow/ As a part of our evaluation of Streamflow, we implemented Maged Michael's lock-free allocator as described in Scalable Lock-Free Dynamic Memo

Hoard is a fast, scalable, and memory-efficient memory allocator that can speed up your applications. It’s much faster than built-in system allocators: as much as 2.5x faster than Linux, 3x faster than Windows, and 7x faster than Mac. No source code changes necessary. Cross-platform: works on Linux, Mac OS X, and Windows. Download Hoard now!
