3.2.7 Run-Time Control

-gnatT nnn
The gnatT switch can be used to specify the time-slicing value to be used for task switching between equal priority tasks. The value nnn is given in microseconds as a decimal integer.

Setting the time-slicing value is only effective if the underlying thread control system can accommodate time slicing. Check the documentation of your operating system for details. Note that the time-slicing value can also be set by use of pragma Time_Slice or by use of the t switch in the gnatbind step. The pragma overrides a command line argument if both are present, and the t switch for gnatbind overrides both the pragma and the gcc command line switch.
