The following modified topic will appear in a future version of the IBM Cognos TM1 Installation and Configuration Guide.
Sets the maximum number of threads per TM1 query.
Parameter type: optional, dynamic
To specify a maximum number of threads to use when processing queries, add the
following line to Tm1s.cfg:
where n represents the number of threads to be used for a single query.
If there is no MTQ entry in the tm1s.cfg file, MTQ is treated as being disabled.
Setting MTQ=1 or MTQ=0 disables multi-threaded query execution as well.
To set the value to the maximum number of cores available on a server, the value of all (case insensitive) can be used. For example:
This will result in a dynamic system setting that will consume all cores.
If you set MTQ equal to a negative number, that is, MTQ=-N, the number of threads that will be used is defined by the following equation:
where T= the number of threads to be used by the system
M= the number of threads on the computer
For example, if your computer has 64 cores and you set MTQ=-10,
Therefore, the system will use 55 cores.
