i tested DPPC on our dual dualcore opteron machine. unfortunately i
lost the results and cannot do the tests right now. however, i have the
results for quad dualcore opteron (i.e., speedup up to 8 processors). i
remember that the scaling was very similar between the two machines...
in both cases, each processor had 1 gb of RAM (i.e. 4/8 GBs total,
the numbers follow. first row is number of processors, second line the
DPPC 1 2 3 4 5 6 7 8
opteron 1,0 2,5 3,7 4,9 5,8 6,7 7,6 8,8
setup - lam-7.1, intel compiler version 9. on the dual dualcore machine
it was lam-7.1, pgi 6.1. the bigger machine is not owned by us and there
is not yet pgi compiler on it, so i couldn't try gromacs with pgi there...
