2. GLAST LAT ProjectAll Hands Meeting – May 11, 2005 R. Claus 2 Outline LATTE is a platform independent framework in which to run application (test) scripts Data products are collected and archived in central storage Tools are provided to monitor on-line activity, as well as to diagnose results off-line LATTE-5: what’s coming

3. GLAST LAT ProjectAll Hands Meeting – May 11, 2005 R. Claus 3 LAT Test Executive LATTE provides a scripting environment Applications (test scripts) use it to exercise functions of a simulator or real hardware LATTE and application scripts are written using: –Python: An open source scripting language –Qt: A multiplatform GUI building toolkit –XML: A tag-based syntax standard for describing structured data Operating system Test Executive Script Functions Dispatcher Local Area Network Computers Hardware (LAT)
