TMCALGO V2R1: Algorithm Compiler

0.0: Introduction

In the ARP Data Acquisition Architecture, TMCALGO is the tool that closes the gap between data collection and process control. It provides a concise language to monitor and manipulate data, make decisions and issue commands. As such, it is the focus of most of the development and many of the ongoing changes in an experiment.

TMCALGO is built upon the groundwork laid by TMC and CMDGEN. The algorithm is compiled to TMC code, and instrument commands are specified using the same syntax as is used for interactive commands. Integration of the algorithm into the software architecture is entirely via QNX messages, allowing the algorithm to run either locally on the experiment's computer or remotely on a GSE computer.

Algorithms can take advantage of the architecture's ability to replay logged data, allowing for detailed analysis and debugging. This can also be used to verify algorithm changes against previously logged data, to help guarantee that normal operations will not be altered.
