Power Shutdown this Saturday (2014-03-08)
I apologize for the late notice, but I just received word that the Wright State University Engineering building where the MindModeling servers are located will be shut down temporarily this Saturday 2014-03-08 from 0700-1200 EST. I will be turning off our servers several hours in advance to facilitate a graceful shutdown. During this period, you will not be able to access our scheduler, this website, etc. There is a chance that I may not be able to remotely power-on the devices, in which case we will not have access again until the following Monday.

MindModeling Server Migration
This morning we migrated our production system from it's home at the University of Dayton to it's new location at Wright State University. This allowed us to:
- Completely decouple our development and production systems
- Increase RAM, disk space, CPU cores, and I/O performance

If you experience any issues, please report them to the forums and we'll address them as soon as possible. However, I suspect a quick reset or detach/reattach of the project may fix a lot of problems, so give that a try first.
And as always, thanks for providing all of the invaluable resources to furthering cognitive modeling research. We've had an incredible couple of months, crunching 127,400+ days worth of computations, and it couldn't have been done without you!
Looking ahead, we should have a new web interface deployed soon and a new version of our CCL wrapper.
CogSci 2013 and Other Updates
Since the last news post, CogSci 2013, the annual meeting of the cognitive science community, held it's conference in Berlin, Germany. From the CogSci's website:
CogSci 2013's theme is "Cooperative Minds: Social Interaction and Group Dynamics." This theme reflects a rapidly growing interest in the Cognitive Science community, namely a move from the study of individual cognition to the social realm. A further topic will be Cognitive Interaction Technologies, a rather new field aiming at a thorough understanding of the processes and functional constituents of cognitive interaction in order to replicate them in technical systems.
In addition to attendance from several researchers in our lab, cognitive scientists from all other the world get together to their latest theories and data. You can visit their website here: http://cognitivesciencesociety.org/conference2013/index.html.
Or checkout the proceedings (hosted by MindModeling.org) here:
Previous years proceedings are also available from links under the Science tab in the MindModeling navigation bar.
Also, the project will be pushing out a new feature soon which captures the average model runtime for each job to more precisely target workunits to one hour (specifically for tasks with variable runtimes). This is currently in the testing phase.
-Ongoing development of a new web UI for volunteers
-Ongoing developing a new screensaver application that is compatible with all of our cognitive modeling platforms and projects (in-progress)
-Ongoing development of infrastructure controlled sampling to allow researchers to specify how much each individual parameter set should be sampled and aggregated before accepting.
-Project descriptions available here: http://mindmodeling.org/forum_thread.php?id=681
More work on the horizon!

New Apps Released!
Yesterday we released a new app version for each of our supported platforms. Below are the latest versions:
- CCL v2.06
- Java-1.7 v1.03
- Pypy1.9 v3.04
- Python-2.7 v1.03
- R2.15.1 v104 (Linux and Windows only)
16 Jul 2013, 16:19:49 UTC
The applications were updated to unarchive large packages and libraries into the projects directory, as opposed to the slots directly, once for the lifetime of the archive. This reduces the overhead that is required to unarchive each package into the slots directory, and may reduce the amount of total disk space the project uses at runtime. Please let us know if you notice any problems associated with these new versions.
Updates and Thank Yous
I just wanted to take a second to thank all of our volunteers for the awesome crunching over the past couple of month. Since March, we've completed 75 jobs across several different research lines (e.g., fatigue studies, integrated learning models, ideal observer and attention tasks) authored in multiple programming languages (e.g., C/C++, Lisp, Python, R). That amounted to 26K days worth of computation completed in ~70 days!!! . It could not have gotten done without your support and resources. We would also like to take this opportunity to acknowledge our top volunteers (by recent average credit):
While our researchers have been busy creating, running, and analyzing models, our developers have been adding new features and extending support. Here's a few things we've been up to:
- Integrated web data visualizations for researchers
- Tools for running and evaluating decision trees (i.e. Fast & Frugal Trees) on volunteer and parallel resources as part of a new research line
- Support for models written in Java
- Bayesian model support in the R statistical language
- Updated server to lastest version of BOINC source tree
And here's some tasks on the horizon:
- Support for Matlab models
- Project descriptions associated with each job
- Rolling average runtime calculations for more precisely targeting workunits to one hour for tasks with variable runtimes
- Server distribution to Wright State University for faster download/uploads, more system memory and disk space, and better CPU utilization
