/* PARAM_SIMULTANEOUS_PREFETCHES is the number of prefetches that
can run at the same time. More important, it is the threshold
defining when additional prefetches will be dropped by the
hardware.
The UltraSPARC-III features a documented prefetch queue with a
size of 8. Additional prefetches issued in the cpu are
dropped.
Niagara processors are different. In these processors prefetches
are handled much like regular loads. The L1 miss buffer is 32
entries, but prefetches start getting affected when 30 entries
become occupied. That occupation could be a mix of regular loads
and prefetches though. And that buffer is shared by all threads.
Once the threshold is reached, if the core is running a single
thread the prefetch will retry. If more than one thread is
running, the prefetch will be dropped.
All this makes it very difficult to determine how many
simultaneous prefetches can be issued simultaneously, even in a
single-threaded program. Experimental results show that setting
this parameter to 32 works well when the number of threads is not
high. */

The Oracle SPARC Architecture (previously the UltraSPARC
Architecture) specification states that when a PREFETCH[A]
instruction is executed an implementation-specific amount of data
is prefetched, and that it is at least 64 bytes long (aligned to
at least 64 bytes).
However, this is not correct. The M7 (and implementations prior
to that) does not guarantee a 64B prefetch into a cache if the
line size is smaller. A single cache line is all that is ever
prefetched. So for the M7, where the L1D$ has 32B lines and the
L2D$ and L3 have 64B lines, a prefetch will prefetch 64B into the
L2 and L3, but only 32B are brought into the L1D$. (Assuming it
is a read_n prefetch, which is the only type which allocates to
the L1.) */
