Hello,

Since you don't publish information on a regular basis, at least here, would you please be so kind to tell us a little bit more about the actual and futur projects ?

Concerning the applications, nothing new since 2009 ...

Is this in line with your strategy or reason is lack of time for developpment ?

Thank You !

Kind Regards

Philippe

Dear philippe,

this project is not a single research project with one goal; in this project we can have several smaller (student) projects throughout the year. As it happens this week we will have some students running argon simulations on BOINC.

When a bigger research project is started and BOINC is used, it will be mentioned here. As it happens, it is not that easy to simply use BOINC for all our research, BOINC is just one of the many computational resources we have available. Also because BOINC (application) development is not for the faint harted, we tend to use the BOINC applications we already have running.

Currently we use BOINC for two things; one in teaching students; they run any type of classical trajectory they want whenever they want. As it happens this feature is open to the public too. Just look in your account on this project and see that you have a private 'queue' to submit Classical calculations into.

The other long term on going (pet) project of mine is investigating (rare) events in a specific water model. This project is a 'gather statistics and wait and see if the even happens' type of project; many many many runs are needed and the chances of any event happening are slim. To this end we continuously feed tasks into BOINC using the same input file over and over. Now due to a special trick we implemented in our application code, a random number generator seed is set and based on the work unit name. This will make sure that each individual run (although the input seems exactly the same) is an individual run. Once enough statistics are obtained we can conclude if this specific water model does feature rare events. If it doesn't, or it does wrongly so, we need to change the water model again and obviously start all over again. Now because this is a pet project me and the chances are slim to get any scientific publication in the sort-run about this, the work for this project is used as a feed when other sub project of Leiden Classical are not using BOINC.

Apart from all that, you do also need to know that this Leiden Classical thing is a sort of one man show; in our group I need to maintain and run this project on my own and I do have other stuff to do as well :-).

Hope to have informed you a bit.

If you want some more info you can have a look at http://theorchem.leidenuniv.nl

Thanks M. Somers for your detailed information, I hope those unused processor
cycles will be a contribution or help to any investigation at the university.
Even a 'pet' project can be very usefull or helpfull in understanding as to why
something does or doesn 't behave to certain law's .
