Compiling QUEST with GNU Compilers on CentOS

QUEST (QUantum Electron Simulation Toolbox) is a Fortran 90/95 package that implements the Determinant Quantum Monte Carlo (DQMC) method for quantum electron simulations.

Compiling under gcc is complete breeze. Just do a simple.

# tar -xzf QUEST-1.3.0.tgz

# cd QUEST-1.3.0

# make

For different environments, please edit the make.inc file to suit your system. FOR GNU, you do not need to

For testing, you can go to  QUEST-1.3.0/EXAMPLE/verify

# ./verify
