Managing Remote Memory.
The remote memory management services provide
the means for sharing memory regions with remote processes. A memory region
is made available to remote consumers using a share/accept model
whereby the owner of the memory creates and shares a remote memory handle
which is then accepted and used by remote processes.
Note: With the exception
of dacs_remote_mem_query(), the remote memory handle can only
be used on DaCS memory transfer services by the remote processes,
and only after they have accepted a share. The owner of the shared memory
cannot use these services.
Note: When DaCS for Hybrid is being
used with DaCS for Cell, remote memory that is created on the PPU (using dacs_remote_mem_create())
can be shared with both the x86_64 (HE) and with the SPUs (AEs). If this is
done then either can use the put or get services to get from the memory shared
by the PPU.
