The latest release has been made. Aside from the usual smattering of bug fixes (nothing too big), there have been many performance improvements between jACT-R and the IDE which will be immediately noticeable in terms of speed and memory usage. Incremental compilation and content assist are now dramatically faster. The memory leaks associated with massive log views now appears to be crushed.

New release is available of core, ide, and actr/s. This covers tons of stuff, there have been quite a few changes, mostly related to compatibility and performance. There is a new framework for dealing with efferent control and it is working well for vocal and I'll be updating motor shortly. I'll be releasing a new augmented tutorial soon-ish.

There is a new release available, this one finally fixes the blocked start-up that could occur. It turns out there is an issue with MINA that would drop a message if the client connected too fast. Irritating, but hacked around until a genuine fix is available.

This release also includes some performance improvements for multiple or embodied models in the neighborhood of 5-15% (all depending). Enjoy.

At the most recent ACT-R workshop, John Laird of SOAR fame, was curious as to the performance of ACT-R. Since ACT-R hasn't been concerned with this (in the past) the numbers weren't available off the top of Dan's head. I had some available, and now Dan and I are working on some common benchmarks, synthetic, but at least they are common.

Here are some early numbers before I dive into realtime issues and database backed models:

Big old batch of bug fixes as I make the mad-dash to the ACT-R workshop. Most of the fixes have to do with concurrency and stability. The intermittent lock-up on start has finally been diagnosed thanks to access to machines with many more cores. It looks as though some long standing motor module issues have finally been resolved allowing commands to be correctly handled when aborted by the model or common reality. Finally, the remote execution tool has been modified so that it can work correctly over VPN connections (the server is now the only one that runs a web service).
