Dear Carlos,
If you go to
http://www.rosswalker.co.uk/files/amber7_bench.xls there is
an excel spreadsheet of a range of amber 7 tests I have conducted using
dual processor athlon 2200MP's with gigabit and scali.
Using lam 6.5.9 with the intel v7.0 ifc compilers with -D_REENTRANT,
-O3, -tpp6 options and including -DMPI, -DROWAT and -DRLE in the system
flags at compilation I can get (for LADH ca 76000 atoms) 9.58x speed up
over 16 cpus with scali and 8.69x speedup for gigabit.
For the JAC benchmark I get 7.68x speedup over scali (16 cpus) and 6.14x
over gigabit which is essentially the same as those quoted for redfish
on the amber website.
I hope this helps
All the best
Ross
