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

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

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

5. 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

6. 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

7. 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

8. 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

9. 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

10. Xeon continued …

11. 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

12. 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?

13. 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

14. AMD continued …

15. Apple’s G5 Execution Core

16. Apple’s G5 Architecture

17. Performance

18. 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

19. 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

20. 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
