Can anyone make sense of the following extract from a paper(pdf):
Compare and swap (casx): This instruction swaps the contents of one memory position allocated in the L2 data cache with the value of a register. This means that this instruction always accesses a memory location in L2 cache.
How (On Solaris, possibly only in assembler?) do you allocated a piece of memory such that "This means that this instruction always accesses a memory location in L2 cache.".
I'm trying to work out how to apply their work on a Intel processor. The Perl link is another attempt at trying to make efficient shared memory available to from Perl.
