HEP programs commonly have very flat execution profiles, implying that the execution
ime is spread over many routines/methods. Consequently, compiler optimization should
be applied to the whole program and not just a few inner loops. In this talk I,
nevertheless, discuss the value of extracting some of the most solicited routines
(relatively speaking) and using them to gauge overall...

way of generating analysis frameworks out of a short experiment description. The
generation process is completely experiment independent and can thus be applied to
any event based analysis.

Ongoing research has shown that testing grid software is complex. Automated testing
mechanisms seem to be widely used, but are critically discussed on account of their
efficiency and correctness in finding errors. Especially when programming distributed
collaborative systems, structures get complex and systems get more error-prone. Past
projects done by the authors have shown that the...

Releasing software for projects with large code bases is a challenging task. When
developers are geographically dispersed, often in different time zones, coordination
can be difficult. A successful release strategy is therefore paramount and clear
