Heres a visual guide to the new multithreading feature in IBM Cognos TM1 10.2.
-
TM1 10.1 and prior releases do not utilise all cores for a single calculation request.
In the given example above the calculation stage of answering a request from a user takes up 99% most of the processing time for the request. So within TM1 10.2 the request calculation is split into chunks which are then delegated to separate CPU Cores. The enhanced performance can be calculated as:
Where:
- ‘e’ is enhancement.
- ‘t’ is time.
- ‘n’ is the number of cpu cores.
