General introduction to Gaudi/DaVinci #4

Closed betatim closed 8 years ago

betatim commented 9 years ago

5min summary of the buzzwords one needs to know to make a little sense of what happens in DV.

(as in not "Gaudi is an object orientated framework with tools, algorithms, public tools, ...")

ibab commented 9 years ago

Some more general questions I would like to see answered as part of the workshop (not necessarily this lesson):

Which problems specific to HEP/LHCb is Gaudi designed to solve?
What are Algorithms and Tools?
What is an option file?
What is the relationship between DaVinci and Gaudi?
What are lb-run and lb-dev?
How do I run Gaudi using my option file?
How can I browse the code/documentation of the LHCb software?
How can I check out an LHCb package?

kdungs commented 9 years ago

I can write something about those points. Might have to leave some holes but I'll see what I can do.

kdungs commented 9 years ago

First steps here: https://github.com/lhcb/first-analysis-steps/tree/content/gaudi-general

Need to set up my Mac now, will continue later. Feel free to add stuff (especially the first three points...) in the meantime.

betatim commented 9 years ago

Woah, why not fork and do your stuff there! I thought we were discouraging people doing stuff in the repo :-/

kdungs commented 9 years ago

No you misunderstood. Discourage doing stuff on master.

betatim commented 9 years ago

That is clear, to me the extra level of forking is still a good idea and means none of us are special.

Ah I hadn't gone through the 30 notifications yet... I see you already merged contribution guidelines, then of course I will do as they say.

@ibab:

How can I check out an LHCb package?

Do you mean "(svn) checkout" or "check out what's inside"?

ibab commented 9 years ago

I mean a quick tutorial on how to use getpack and maybe how it translates to svn.

kdungs commented 9 years ago

What is a typical project one getpacks when working with DaVinci?

alexpearce commented 9 years ago

Phys/StrippingSelections maybe?

ibab commented 9 years ago

Maybe Phys/DecayTreeTuple
