Obtaining the source code

• Version control through gitHUB:

  git clone [email protected]:phys-tools/pi-qmc.git
  

• Download ZIP File: https://github.com/phys-tools/pi-qmc/zipball/master

• Download TAR Ball: https://github.com/phys-tools/pi-qmc/tarball/master

Building with cmake (recommended)

Running "cmake ." in the source directory configures the program. After the program is configured you can always edit settings in CMakeCache.txt.

You can set the intel compilers with:

env CC=icc CXX=icpc cmake .

To generate an eclipse project with gcc-4.7 tools from mac ports:

env CC=gcc-mp-4.7 CXX=g++-mp-4.7 cmake -G"Eclipse CDT4 - Unix Makefiles" .

Building with legacy autotools (supported, but not recommended)

Important configure flags:

• Compile the code for 1, 2, 3 or 4 dimensional simulations. (Four dimensional simulations are mostly used for testing spin algorithms or other mathematical models.)

  --with-ndim=NDIM
  

• Enable MPI for parallel simulation.

  --enable-mpi
  

• Use the SPRNG library for random numbers.

  --enable-sprng
  

• If configure has trouble locating the proper blas and lapack libraries:

  --with-blas=<lib>
  --with-lapack=<lib>
