[Beowulf] Fastest way to compute Euclediant distance [spin off from: Building new cluster - estimate]

2008-08-07 Thread Eric Thibodeau
Most of the arguments I have heard are "oh but its compiled with -O3" or whatever. Any decent HPC code person will tell you that that is most definitely not a guaranteed way to a faster system ... Hey...as I stated above, one would have to be quite silly to claim -O3 as the all well and all

2008-08-07 Thread Peter St. John
Maybe in the 32-bit compile, a value is stored in a 64-bit register, and when it gets "robbed" (to populate the missing value for an adjacent variable) the 32 bits of backfill are taken, so the remaining value is good; but in a 64-bit compile, all 64 bits are taken so the remaininder is rubbish.
