Hi Matthew,

One way is to link against a multi-threaded LAPACK library on your system. Another way is to use QMC codes if the coupling between the dimers is not strongly frustrated. I could help you more if you send the parameters and lattice structure

I am using ALPS to examine the excitations, temperature and magnetic field dependence of a coupled dimer system. I would like to use the fulldiag code. Are there ways to implement the use of multiprocessors for this code? currently I am using the commands

input_file=pyalps.writeInputFiles(‘parm’, parms) res = pylaps.runApplication(‘fulldiag’, input_file) data = pyalps.evaluateFulldiagVersusT(pyalps.getResultFiles(prefix=’parm’),Delta_T=1.0, T_min=1.0, T_max=51)

as described in the tutorial pages.

Thank you,
