TBCI 2.6.3 - Changelog

What's new in TBCI 2.6.3:

February 6th, 2012

· This version has a few minor bugfixes and performance improvements.
· The code has received minor adaptations to compile fine with icc-11.1 and gcc-4.5+.
· Usage of HOT/COLD attributes has been implemented, but disabled by default (did not help in tests). cplx:power(double) has received a bugfix.
· There are some cleanups and performance improvements in the SMP parallelization infrastructure.
· Most notably, this release can do short busy-waiting before yielding a core, which results in less context switches and better SMP performance.

What's new in TBCI 2.6.1:

September 8th, 2009

· The CPU detection code now handles intel hyperthreaded CPUs specially; it will by default only schedule a compute thread on one of the hyperthreads. This improves performance.
· The packaging has been cleaned up and is now much more in line with openSUSE and Debian packaging conventions.

What's new in TBCI 2.6.0:

September 8th, 2009

· This release features a few performance enhancements.
· It will detect core2 and Nehalems correctly and optimize for them.
· thread_control structures have been rearranged for reduced cacheline bouncing, especially for the thread-safe memory allocations via malloc_cache (binary incompatible with 2.5.x).
· A few bugfixes have been made.
