The job types I have seen or seen mentioned are;

Comix
Sherpa
Herwig
Vincia
Pythia 6
Pythia 8
Epos

Crystal Pellet has copied a description of EPOS, but I don't know where that has been taken from.
Could we get a similar brief description, please, (dumbed down for the layman if possible) of what the other job types are doing.

The best guy to deal with this, Peter Skands, is not back in the office until 30th November. Hopefully, if his desk hasn't been piled too high during his absence, he will be able to give us some idea of what's going on inside the different flavours of model.

Hi Ray,

Apologies for the long wait. Your question is very good. In fact, I think we should write something about this on the T4T homepages, so I've started putting a little page together about that, hopefully ready within a few days. I'll post a link here when it's up!

Related to this: are T4T simulations LHC-specific or are they useful for other colliders, including future colliders like CLIC and ILC?

Hi yo,

In brief, they are useful for both LHC and for future collider studies. Similarly, we run comparisons not only to LHC but also to a number of experiments at older accelerators, like Tevatron, SPS, LEP, and SLAC. For the specific purpose of making guesses about what things might look like at future colliders, we look at the energy scaling between the previous ones, and extrapolate, so this is quite an important part to get right.

Ray, sorry I didn't get the page up yet. Working on it ...

Hi there

Like to add one to the above list:

Phojet

(appears rather seldom, just seen one after several months)

Greetings,
Bylo

Hi,

Time to apologize again for the slow motion in getting these descriptions ready for you. Christmas and a busy January filled with travel are my excuses this time. All of February I will be at CERN though, working away in my office, so should get time to write these. Just to let you know I did not forget my promise to give some slightly more elaborate explanations about each of the sim packages.

Thanks for that update, Peter.
It's possibly a tough assignment, to get the wording right to be of interest to more learned contributors while not being too far over the heads of the interested but not qualified lay-person, like myself.

Peter,I just saw your name on a job running in my old BOINC_VM window and this reminded me of your promise to explain us what all those jobs are doing. I am running also VBoxHeadless on another PC but there I see nothing. Maybe it is my fault, since it is running in a Ubuntu 10.30 Virtual Machine, upgraded to 11.1 during installation on my main Linux box with SuSE 13.1, whose VirtualBox 4.3.6 is not seen by T4T, and I am still a Ubuntu dummie.

I have downloaded a CERN Openlab 56 pages PDF document, a Whitepaper on future IT challenges in scientific computing but it had no information on what we are trying to do.

Hi Tullio,

This document is supposed to suggest joint projects for CERN and its Openlab industrial partners to work on over the next 5 years, with possible collaborations with some other European labs. It doesn't seem to be a suitable environment for work on volunteer computing, due to the industrial component. (I talked to its main author yesterday about this).

Thanks for your post,

Ben

Ben, I know that industry is going the cloud way. In France, Atos has just bought my old employer Bull.

Hi,

Here is a link to a post that (hopefully) answers the original question....

http://lhcathome2.cern.ch/vLHCathome/forum_thread.php?id=1325&postid=15098

Perhaps this could be copied to the main web page to act as the introduction to the project..??

Thanks, Jay

Yes, but we wanted something more specific. I am seeing all kinds of CERN jobs, such as sherpa, herwig, etc, and I would like to know something about them. Peter Skands had promised to give us at least a summary.
