ENEA Grid infrastructures [2]
Main features:
- Access from any kind of connection
- Sharing data in world wide areas (geographical file system AFS)
- Access to the data from any kind of digital device client
- Running any kind of programs
- Access to National and International GRIDS
For each computational site, ENEA manages
Local Networks (LAN) whereas the
computational
centres
(WAN)
are
interconnected via
“Consortium GARR”
Network

Gromacs on ENEA Grid (CRESCO)
Protein in a box of water at ISA CNR, Avellino: A. Marabotti
GROMACS is a versatile package to perform molecular dynamics, i.e. simulate the Newtonian
equations of motion for systems with hundreds to millions of particles.
It is primarily designed for biochemical molecules like proteins and lipids that have a lot of
complicated bonded interactions, but it can be used also for research on non-biological systems, e.g.
polymers.
Dimeric protein +
water + ions: ~77000
atoms. Timescale of
simulation: 5 ns
Simulation made on
16 cores on Cresco1,
Time required: 40 h.
Same simulation on
cluster dual-core
AMD Opteron (Gbit
Eth): 10 gg. no
scaling beyond 2
cores
Peptide + water + ions: ~2500 atoms
Timescale of simulation: 40 ns
Time required: 24 h (on 8 cores smp Intel Xeon)

Gaussian/cp2k/RosettaDock on ENEA-Grid(CRESCO)
Chemical Reactivity at the University of Salerno. Dipartimento di Chimica: Prof. Cavallo
1) Static DFT calculations (Gaussian)
Working in shared memory
with 8 cores maximum/job
Usually 10 jobs/day
Speedup ~4-5
2) Dynamic DFT simulation (cp2k)
(Car-Parrinello MD)
working with MPI, the code
scales well up to 64 cores
Usually 1-2 jobs max/day
Speedup excellent (~60)
Olefin Metathesis, the Nobel 2005 Reaction
Structural Bioinformatics (rosettacommons)
Simulating Antibody/Antigen
recognition through docking simulations.
Typical embarrassingly parallel
problem. No limits to the speedup, 1 core per job.
Using ENEA Grid technologies: we have run
tipically up to 500 jobs/day
With speedup excellent (500) and efficiency 100%
