DCACHE_SIZE
Posted: Wed Nov 08, 2006 12:00 pm
Maybe this has been asked before, but how does one find the optimal DCACHE_SIZE value? For linux on P4 systems, the default makefile says
12000 for the serial and 4000 for the MPI version... How can I determine the
correct value for DCACHE_SIZE for my system? Or are these values correct for
every linux system? I saw somewhere that for the serial version at least, using
Jurgen Furthmuller's fft, DCACHE_SIZE should be increased to 16000.
Any comments are welcome.
Thanks
