MULTIPROCESSING DG To what extent is
multiprocessing designed into the 360/370 architecture?
This performance boost essentially is "free" in both hardware and software, as the additional hardware threads in the cores are minimal in size relative to a typical SoC design, and multi-threading makes use of the same Symmetric
Multiprocessing (SMP) versions of operating systems and software programming models as coherent multi-core platforms.
Symmetrical
multiprocessing and superclustering are not new concepts, of course.
SGI says that the unit uses similar symmetric
multiprocessing techniques as that employed in the Cray T90 and J90 series, and that the machine's vector cache memory provides up to 25.6 GB/sec in memory bandwidth.
Mazzola also highlighted the fact that Unigraphics Version 16 will be tuned for the Intel Architecture and will feature the symmetric
multiprocessing (SMP)-enabled Parasolid solid modeling kernel.
The ARM11 MPCore multi-core processor is capable of processing rates in excess of 750MHz in current 90nm process technologies and offers the full scalability of
multiprocessing. The ARM11 MPCore multi-core processor supports software compatible, symmetric multi-processor (SMP) operating systems and real-time operating systems (RTOS).
The processor is designed specifically for
multiprocessing servers and workstations and includes Smart MP technology for increased data movement, QuantiSpeed architecture for enhanced performance and 3DNow!
It differs from
multiprocessing in that a
multiprocessing machine runs a single copy of the operating system.
As there is supposedly no latency penalty it is more akin to a conventional symmetric
multiprocessing system than a ccNUMA system.
Like other members of the Pentium II Xeon processor family, the new Pentium II Xeon processor at 450 MHz delivers industry-leading performance from its larger and faster Level 2 (L2) caches,
multiprocessing capabilities and 100-MHz system bus.
