Hot Processors Of Today COSC 3P93 Nov 29 2004 Steven Barkovic

Introduction Computers have vastly improved over the years Adaptation of problem solutions to the architecture available The limit is near …. Parallel Processing Technological limitations

Introduction continued … What do experts think about the state of the industry today? Where do you guys see the industry going in the future?

Marketplace Today Pentium Line Pentium 4 Itanium 2 Xeon Apple’s G5 AMD Line Athlon

Intel’s P4 With Hyper-threading P4 with hyper-threading is available from 3.2 to 3.8 GHz Intel’s Extended Memory 64 technology http://developer.intel.com/technology/64bitextensions/

Hyper-threading Allows a single processor to function as two logical processors Shared cache’s, buses and execution units Its is recommended that Hyper-threading be used for Windows XP however not be used on previous versions of windows

SSE2 And NetBurst Streaming SIMD Extensions 2 13 new instructions that extend the Intel processor technology Enhances the performance of applications for digital home use NetBurst uses Source Synchronous transfer of address and data to improve performance of data transfer

Intel Xeon Available in speeds of 2.8 – 3.6 GHZ 800 MHZ system bus Specifically designed for performance dual processor workstations Uses Hyper-threading, NetBurst and SIMD Extensions technology just as the P4’s do

Xeon continued … Uses PCI-Express which enhances performance for data intensive applications Industry transition from a parallel I/O to a serial I/O DDR2 memory provides better memory bandwidth as well as reducing latency

Xeon continued …

Intel Itanium 2 Up to 1.6 GHz Can scale up to 128 processors or more EPIC technology – Explicitly Parallel Instruction Computing which addresses high end and technical workloads Up to 1024 TB of memory addressability

Itanium 2 continued ... The weather channel & weather.com are carried by 98% of US cable households Provide services beyond TV such as weather updates to PDA’s, hotels and ISP’s They needed to replace two older RISC based database servers and chose Itanium 2 servers Why?

AMD Athlon MP For Servers Smart MP technology which offers dual buses Cache coherency protocol manages data and memory traffic “Snoop” buses facilitate inter-CPU communications QuantiSpeed architecture ensures exceptional server performance

AMD continued …

Apple’s G5 Execution Core

Apple’s G5 Architecture

Performance

Some Extra Interesting Facts US government is deploying 1566 XServe G5 servers to create one of the worlds fastest supercomputers which can calculate 25 trillion calculations per second Developed through a partnership with IBM

The future …. Intel is working on photonic connections to be out around 2010 which can exchange data via laser light This is already in use when data is moved to or from CD’s and fiber optic networks Optical connections can run high bandwidth over long distances

Conclusion Dual processing is the trend for the future As long as the architecture keeps up with the processor speed then we can create efficient machines
