"Memory is the real bottleneck," says IBM Fellow and director of server design Jim Rymarczyk, who says that distributed shared memory is the natural extension of symmetric
multiprocessing architectures in which multiple CPUs share a single pool of memory, a unified memory architecture (UMA).
Ziatech is hosting a new Web site dedicated to open-sourcing its
multiprocessing technology, www.compactnet.com.
Several MIPS licensees are already working on designs leveraging the multi-threaded
multiprocessing MIPS32 1004K(TM) Coherent Processing System (CPS) and multithreaded MIPS32 34K(TM) cores with Android.
Symmetrical
Multiprocessing Helps Integrate Legacy and Newer Code
According to the company, the new platform family includes Teradata 550 SMP (symmetric
multiprocessing), Teradata 2500, and Teradata 5550.
"Unisys, long a price/performance leader in high-end Intel processor-based systems, is continuing this trend by bringing true enterprise class functionality to the Linux environment, to large scale
multiprocessing systems based on both Intel Xeon processors MP and Itanium2 processors."
The RapidIO interconnect architecture also boasts an optional distributed globally shared memory protocol extension that can be used for symmetric
multiprocessing and shared data structures.
The Ultra AXmp motherboard combines four-way
multiprocessing and up to 2GB of memory for high-powered, scalable, embedded applications.
A fully configured SV1 symmetrical
multiprocessing node has six MSP vector units and eight parallel units for a total of 32 processors: the SV2 will take the number of processors into the hundreds.
Red Hat Linux 6.0 adds symmetric
multiprocessing support for up to four processors and other new features to deliver improved performance and reliability in enterprise and Internet applications that run the day-to-day business of companies worldwide.
Near the end of the interview, Padegs and Case comment on
multiprocessing, reduced-instruction-set computers, and address space limitations.
