SMP and MPP differences

[EDWDBA]

Hello Folks,
Can you please share your expriences with Teradata SMP systems(single node)?

1. First of all, are there any clients still using this machine?
2. What are the NCR machines (WorldMark 4800?) supporting SMP?
3. Whats the next compatile Hardware to make it MPP?
4. Whats the MAX size (in Terabytes) an SMP can store and MAX number of Nodes/AMPs?
5. Did NCR published any white paper with Pros and Cons of SMP and its comparision with MPP.

Thanks for your time.

MPP
1 Stands for Massively parallel processing
2 A computing that uses many CPUs in parallel to execute a single program
3 CPU has its own memory which prevents hold up
4 Does not suffer from bottleneck when all CPUs attempt to access memory once
5 Difficult to program as applications must be divided to communicate with each other
SMP
1 Stands for symmetric processing
2 A computing where many CPUs are available for individual processes simultaneously
3 CPU attempts to access the memory at once, so there is hold up
4 Does suffer from bottleneck when all CPUs attempt to access memory once
5 Easier to program

If you go into the NCR online documentation there is one that says SMP Utilization Manager's User Guide.

The SUM(SMP Utilization Manager) talks on how you can launch processes, detect processes and so on. Maybe you could get some idea if you read that.

Shridana -
Thanks for your explanation. If you can, please read the questions again and answer appropriately.

Thanks again
