At a Glance
Picotm is a system-level transaction manager. It provides transactional semantics for low-level and operating-system functionality. It's flexible and extensible to cover exactly your requirements. Error handling and thread isolation are provided by picotm, all you have to implement is the application logic.
Picotm is implemented in plain C and is well-suited for implementing applications and firmware that is secure, reliable and thread-safe; yet easy to develop. This makes picotm well-suited for multi-threaded and fault-tolerant software.

Fwd: Scaling Lock Performance
The next release of picotm will feature a number of improvements to the locking code, and specifically to the transactional-memory module. Locks will be more scalable and transactions have now bounded execution times, guaranteeing progress of the system as a whole.
In my blog, I posted an article about the upcoming changes and how they affect the results of picotm’s performance tests.
Best regards

Fwd: Benchmark Visualization with LaTeX and gnuplot
