VASP-MGCM

The VASP-MGCM (Vasp-Multigrid Continuum Model) available in tekla2 has been compiled in the VASP 5.3.3 version (normal and gamma version). To perform a calculation of a solvated system PLEASE read first the following pdf guide --> vasp_mgcm_guide.pdf. After that, one needs to slightly modify your running script. The two only lines that have to be changed are those corresponding to the modules and executable calls. For some reason (most likely due to the different fortran libraries used in the tekla2 queues) the code runs at a reasonable computational cost in the c8m24.q. If there is enough space in this queue run your calculation there, otherwise use the c24m128ib.q although the speed is much lower there at this moment.
