icm/wp_roll_timeout

Use

You use this parameter to determine the maximum time that a work process can run on the ICM when reading data, before the user context is rolled out.

With slow network connections and large volumes of data, the read time can become very slow (> 600 seconds). This parameter can prevent the work process from being blocked for a long period of time, even through it can only read small datasets. The context is then rolled out and the work process is available for other tasks. The data affected can be collected in an MPI and then fetched by a work process.

Value Range and Syntax

You can specify values between 5 and 3600 (between 5 seconds and one hour).

You must set the parameter to be smaller than the value of parameter rdisp/max_wprun_time (the default setting is 600 seconds), since processing in the work process is terminated anyway after this time period.
