Hi, I have installed Alps on a computer running SUSE Linux Enterprise Server 10 (x86_64) using Intel Compilers. The following is the result of 'make test' The following tests FAILED: 8 - hello_fortran (Failed) 9 - ising_fortran (Failed) 42 - lattice_constant_test (Failed) 80 - h5d_cpx_flt_ (Failed) 81 - h5dc_cpx_flt_ (Failed) 82 - h5a_cpx_flt_ (Failed) 83 - h5ac_cpx_flt_ (Failed) 88 - h5d_cpx_lng_dbl_ (Failed) 89 - h5dc_cpx_lng_dbl_ (Failed) 90 - h5a_cpx_lng_dbl_ (Failed)… [View More]

Hi Simon, with SU(2) symmetry the mean transverse magnetization is always 0 by definition.

spimc questions
by daniel.aravena＠antares.qi.ub.edu 14 Mar '12

Dear all, I am performing some tests using spinmc (alps 2.0, Heisenberg model) on uncoupled spins changing the number and magnitude of spins at different fields. There are some things in the results that I dont understand: The energy is always zero, independently of the magnitude of the field for the uncoupled case, if I put a coupling constant, then I get as expected a non-zero value for the energy, but it is still non-dependent on field as it should be because of the Zeeman term. In a … [View More]

help

Hi, I would like to ask about the definition of the honeycomb lattice in the lib. Firstly, the honeycomb unitcell has 2 sites at positions (0,0) and (-0.28866...,0.57734...). I do not understand the second coordinate. Secondly, is it necessary to have different edge types although they represent the same bond connecting nearest neighbour? Regards, Mike

Andreas, I have the same message after make on Scientific Linux 6.1, nevertheless make install goes smoothly and I did not notice any problems going through tutorial.

ALPS on ubuntu 11.10
by Rafał 03 Mar '12

03 Mar '12

Welcome everyone, It's my first mail to this mailing list, I'm using that's kind of thing first time so if my behave is unpropriate please don't take it offensive. I'd like to ask if anyone of you tried to run ALPS on ubuntu 11.10. I've tried to build ALPS, after doing everyting under "Get dependent libraries and tools on Debian GNU/Linux (sid)", as it was on the wiki: http://alps.comp-phys.org/mediawiki/index.php/Download_and_install_ALPS_2#B… but I've get some serious problem. When I … [View More]
