Error message

Deprecated function: The each() function is deprecated. This message will be suppressed on further calls in node_privacy_byrole_nodeapi_prepare() (line 216 of /var/www/exc/sites/all/modules/node_privacy_byrole/node_privacy_byrole.module).

A new version of the code has been released: v3.1. Few changes and some bug corrections for this intermediate release.

  • parallelization via openmp: now also the Haydock diagonalization is done in parallel using the openmp scheme. in this way the whole excitonic matrix can be kept into memory without writing anything in the disk. this still works only for the resonant spin unpolarized case. It has been tested for the q=0 case only.
  • some python scripts have been added but undocumented yet.
  • implemented the read and write chi0 subroutines
  • small bug correction that prevented to run when compiled with xlf
