Optima@Home: About GULP Application

[RSS]

New application aimed at testing stability of the GULP code.GULP is a program for performing a variety of types of simulation on materials using boundary conditions of 0-D (molecules and clusters), 1-D (polymers), 2-D (surfaces, slabs and grain boundaries), or 3D (periodic solids). Adaptation of this code for BOINC is a first step to implementation of the computational materials discovery methods to the distributed computing. More specifically, USPEX evolutionary algorithm. This is an algorithm for crystal structure prediction, which is a problem of global optimization, i.e., finding the global minimum of the free energy of the crystal (per mole) with respect to variations of the structure. Successful solution of this problem requires local optimization for each structure generated during prediction. GULP is one of the methods supported by USPEX. That is why we have adapted it for BOINC and providing a test caclucation for it.This is variable cell calculation of the crystal structure of magnesium aluminate (MgAl2O4) with 28 atoms per unit cell at 100 GPa pressure.

New app! Yay!

No ability to choose apps! Boo!

Seems to be 32bit linux only as well, my 64bit systems aren't getting any. bitcoin just released the bfgminer app for campaign #3 though, that'll get you to 379apps

[Mumps]

Well, seeing as they haven't had work for any other app for over a year, I'll guess you're safe.

And even according to the project site, there's no user with any recent credit, so it remains to be seen if they're even working.

I got 14 on a 64 bit VM That won't be enough for 100 hours and the server is saying it has no more work There are only 151 tasks in progress.

[Mumps]

Well, I've got 79 of them. All 64bit linux.

[Mumps]

Well, it looks like credits are almost non-existent. After crunching for about 186 hours, according to WuProp, I've been granted a whopping 13 credits, without a single Invalid result. It looks like the key here is that the WU's aren't reporting the correct elapsed time back to the BOINC client.

[Bryan]

Well I got a whole 2 points for my efforts ... I'll never complain about Seti credits again

[shiva]

well, looks like Mumps is the winner once again. Bryan you had to do 7 wu's to get a point while Mumps only had to do 6.07 wu's per credit.

I have the last three tasks, that have been running over a day now. Maybe they are stuck. I will not un-stick them until I hit my goals, or they issue more.
