1. Introduction

Teuthis is a tool to improve the efficiency with which computational scientists make use of computing resources, particularly high-performance computers. It is a control panel from which a user can remotely configure and build applications from local source code, then submit jobs based on those applications, track their progress, and transfer the data they produce to other machines. It dramatically reduces the labor required to manage large numbers of independent calculations, allowing parameter studies to be created with a few simple operations. It is also a notebook which organizes calculations so that they may be examined later within the context of the projects that motivated them. They may be assessed, continued, or repeated as desired. Finally, it is a tool for collaboration, allowing coworkers to share notebook records and examine each other's work. Its development has been motivated by the requirements of numerical simulation, but it need not be limited to this area of computational science. Any computational task that takes a set of input parameters from a file and runs noninteractively can be managed using Teuthis.

Contacting us

To obtain more information about Teuthis, or to download a copy, please visit our web site at http://mazama.ncsa.uiuc.edu/projects/teuthis/.

If you find Teuthis useful, please send us a message at teuthis-feedback@ncsa.uiuc.edu. Put the word "teuthis" in the subject line and tell us your name, your organization, your application area, the name or type of code you're running, and where you are running it (e.g., NCSA, SDSC, NERSC, etc.). This will help us to propose for funds to continue to maintain and improve Teuthis.

Email questions regarding Teuthis may be sent to teuthis-help@ncsa.uiuc.edu. Please remember to indicate which version of Teuthis you are using. Also, it helps if you can enable verbose logging in your user preferences, then attach a small, representative sample of the log file to your email message.

Please keep in mind that our personnel available for support (ie., one assistant professor and a couple of graduate students) are extremely strapped for time. If your question can be answered by looking at the documentation or the FAQ, you will not receive a reply. Even if your question is reasonable we may not be able to respond immediately.
