MPI is the thing and it works. it has little to do with windows, but with the application you use. axel. > > Please let me know at your earliest. > > -- > Kanak Datta > Lecturer > Department of Electrical and Electronic Engineering > Bangladesh University of Engineering and Technology > Dhaka-1205 > Website: https://sites.google.com/site/kanak0806085/home > > _______________________________________________ > Pw_forum mailing list > [email protected] > http://pwscf.org/mailman/listinfo/pw_forum -- Dr. Axel Kohlmeyer [email protected] http://goo.gl/1wk0 College of Science & Technology, Temple University, Philadelphia PA, USA International Centre for Theoretical Physics, Trieste.
