Example Configuration
This section shows the configuration for a system in which preprocessing takes place on one master host and one preprocessor host.
The configuration is only specified for mytrexmaster and mytrexpreprocessor, and only where distributed preprocessing is involved.
Assumptions:
-
Both hosts have 2 CPUs each.
-
Two preprocessors should run on mytrexpreprocessor.
-
The only queue server in the system is running on mytrexmaster.
-
Only searches take place on mytrexslave1/2, there is no preprocessing here.

poolsize= 9
The pool size is calculated as follows:
2 * <preprocessor_threads> on <mytrexpreprocessor>+ <preprocessor_threads> on <mytrexmaster>= 2 * 3 + 3 = 9
