Manuscript Title: A High-Performance Fortran Code to Calculate Spin- and Parity-Dependent Nuclear Level Densities
Authors: R.A. Sen'kov, M. Horoi, V.G. Zelevinsky
Program title: MM
Catalogue identifier: AENM_v1_0
Distribution format: tar.gz
Journal reference: Comput. Phys. Commun. 184(2013)215
Programming language: Fortran 90, MPI.
Computer: Any architecture with a Fortran 90 compiler and MPI.
Operating system: Linux.
RAM: Proportional to the system size, in our examples, up to 75Mb
Keywords: Nuclear level density, Shell model, Parity, Spin.
PACS: 21.10.Ma, 21.60.Cs, 21.10.Hw.
Classification: 17.15.

External routines: MPICH2 (http://www.mcs.anl.gov/research/projects/mpich2/)

Nature of problem:
Calculating of the spin- and parity-dependent nuclear level density.

Solution method:
The algorithm implies exact calculation of the first and second Hamiltonian moments for different configurations at fixed spin and parity. The code is parallelized using the Message Passing Interface and a master-slaves dynamical load-balancing approach.

Restrictions:
The program uses two-body interaction in a restricted single-level basis. For example, GXPF1A in the pf-valence space.

Running time:
Depends on the system size and the number of processors used (from 1 min to several hours).
