Found a very strange problem - see on some processors on boinc benchmarking whetstones score drops, when measure on 64bit OS ( with 64bit client, sure).
take measures on Linux Slackware and Slackware64 OS, client version last - 7.2.33
drystones always rise, as i see.
why there is that situation, and what way that can be explained? why drystones rise, but whetstones drop?
do floating point math on intel processors is optimized for 32 bit operations?
