Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
please forgive me if this is not the right place to ask or if this question has already been answerered somewhere else; it might be very common.
What I am looking for is some comparison between the random engines available with Geant, which is more detailed than the chapter in the manual.
Since my application runs on a computig farm, I'm especially interested in a information about the period of the generators and how to seed them correctly. At the moment, the Ranecu-engine with the job-index as a seed is used. But since the number of seeds is limited for this random engine, I am limited in the number of jobs I can run. To cut down the computing time for each individual job, it would require only minor changes to the application there were 24500 possible seeds.
The easiest might be to use the standard HepJamesRandom and seed it with s=0 ... 24499. Is this advisable?
Can you recommend any documentation to consult?
Thank you very much for your effort.
