In other words how can I constrain x and y coordinates of atoms during relaxation? Regards, Manoj Srivastava University of Florida Gainesville, FL

Dear all, Dear all, We will launch a big program to set up a computer center for Q-E and CPMD. We wonder whether AMD Six-Core AMD Opteron? Processor or Intel XEON 5500 series will give us a more efficient performance. Of course, the infiniband is included in the program. and we design 3G DDR3-1333MHz for each Core (not each CPU). any suggestion will be appreciated. thank you for reading vega -- == Vega Lew ( weijia liu) PH.D Candidate in Chemical Engineering State Key Laboratory of Materials-oriented Chemical Engineering College of Chemistry and Chemical Engineering Nanjing University of Technology, 210009, Nanjing, Jiangsu, China ** Email: vegalew at gmail.com Office: Room A705, Technical Innovation Building, Xinmofan Road 5#, Nanjing, Jiangsu, China ** -- next part -- An HTML attachment was scrubbed...

Maybe it's not reading the input at all! You should specify the full path to you input file, e.g. mpirun ... bin/pw.x -in /where/is/is/ZnO.pw.inp just to be sure. > I am not the supperuser,I don't know how to Set the environment variable > OPEN_MP_THREADS to 1,I can't find where is OPEN_MP_THREADS ? You don't need to be super-user (nor supper-user ;-) to set an environment variable, you only have to add export OMP_NUM_THREADS=1 in your PBS script, before calling mpirun. To be sure it's propagated to all the processors add the option -x OMP_NUM_THREAD to mpirun arguments (BEFORE pw.x). cheers P.S. when answering to a daily digest, please remove the irrelevant parts, and set the discussion title to whatever it was before; this make it easier for other people to follow the discussion! -- Lorenzo Paulatto SISSA & DEMOCRITOS (Trieste) phone: +39 040 3787 511 skype: paulatz www: http://people.sissa.it/~paulatto/ *** save italian brains *** http://saveitalianbrains.wordpress.com/

This usually induces a huge performance degradation. In choosing the optimal number of nodes, processes per node, etc., several factors should be taken into account: memory requirements, communication hardware, etc. You might want have a look to this page from the user guide: http://www.quantum-espresso.org/user_guide/node33.html Also, consider that, at least for not very very recent CPU generation, using too many cores per CPU (e.g. if your cluster configuration is with quad-core processors), might not improve (maybe also make worse) the code performances (this is also reported in previous threads in this forum, you can make a search). Also this can be of interest for you: http://www.quantum-espresso.org/wiki/index.php/Frequently_Asked_Questions#Why_is_my_parallel_job_running_in_such_a_lousy_way.3F > I don't know why it run so slow ,how to solve this problem ? Any > advice will be appreciated ! Apart from better suggestions coming from more expert people, it would be important to see what kind of job you are trying to run. For example: did you start directly with a "production run" (many k-points and/or large unit cells and/or large cut-off)? Did pw.x ever run on your cluster with simple jobs, like bulk silicon or any other (see the examples directory)? Another possibility would be starting with the serial executable (disabling parallel at configure time) and then switch to parallel once you check that everything is working OK. Unfortunately, in many cases the computation requires lot of work to correctly set-up and optimize compilation, performances, etc. (not to speak about results convergence issues). The only way is trying to isolate problems and solve one by one. Yet, I would say that in this respect quantum-espresso is one of the best choices, being the code made to properly work in as many cases as possible, rather then implementing all the human knowledge but just for those who wrote it!!! ;-) Good luck, Giovanni -- Dr. Giovanni Cantele Coherentia CNR-INFM and Dipartimento di Scienze Fisiche Universita' di Napoli "Federico II" Complesso Universitario di Monte S.

So I DONT know which smearing > should I use? the larger or the smaller? > thanks Smearing is used primarily to smooth the fermi discontinuity in metals, allowing to use coarser meshes of k-points. From this point of view, for an atom you'll have gamma sampling and no k-points issues. A secondary effect of smearing is that it helps reach selfconsistency - especially in atoms or molecules where the HOMO and LUMO are close and could swap order during selfconsistency. What you want is to use a smearing that is quite a bit smaller than the converged HOMO-LUMO gap - when that happens, the HOMO is full, the LUMO is empty, and the energy E or the free energy E-TS do not change as you vary the fictitious smearing temperature T. If you have trouble reaching self-consistency in this case, use a larger smearing, and then restart from your converged results with the smaller one. nicola -- - Prof Nicola Marzari Department of Materials Science and Engineering 13-5066 MIT 77 Massachusetts Avenue Cambridge MA 02139-4307 USA tel 617.4522758 fax 2586534 marzari at mit.edu http://quasiamore.mit.edu

But when I change(reduce) the smearing ,the value of energy increase. So I DONT know which smearing should I use? the larger or the smaller? thanks Ali Kazempour Physics department, Isfahan University of Technology 84156 Isfahan, Iran.Tel-1: +98 311 391 3733 Fax: +98 311 391 2376 Tel-2: +98 311 391 2375 -- next part -- An HTML attachment was scrubbed...

[Pw_forum] write occupancy
Hi How do we can force the code to print the occupancy in simple scf run? I know partial dos calculation , but I don't know wheather another way also exist or not? thanks a lot Ali Kazempour Physics department, Isfahan University of Technology 84156 Isfahan, Iran.Tel-1: +98 311 391 3733 Fax: +98 311 391 2376 Tel-2: +98 311 391 2375 -- next part -- An HTML attachment was scrubbed...
