Is there a way for a non-kernel-developer or plain FPC/Laz user to
control what is stored in cpu cache ? I thought cache management
is done transparently to userspace...?
Only on IA-64 ("Itanic") as far as I know, and in any case for
prefetches etc. to be effective the application code would have to be
intimately familiar with the details of the hardware implementation.
It's the sort of thing that would be a compile-time option on a Cray :-)
