DMRG++ Parallel Compilation

Mon, 1 Feb 2016 11:09:35 EDT Faster compilation can now be achieved if your computer has multiple cores. First recompile PsimagLite cd PsimagLite/ cd drivers/ perl make.pl cd ../lib perl configure.pl make Now DMRG++ cd ../../dmrgpp/src perl configure.pl make -j 16 where the example uses 16 cores. Use more or less cores depending on your hardware. IMPORTANT: After each git pull please run perl configure.pl in both PsimagLite/lib and dmrgpp/src

Project Mission

DMRGPP-LOGO DMRG++ is a free and open source implementation of the DMRG algorithm. (The DMRG algorithm was developed by White; original references are White, 1992 and White, 1993. More information about the DMRG can be found, for example, here.) DMRG++ emphasizes generic programming using C++ templates, friendly user-interface, and as few software dependencies as possible. DMRG++ tries to make writing new models and geometries easy, fast and bug-free by using a generic DMRG engine.
