There are three execution modes: concurrent, sequential and 'by group'.

There are several methods to finish a project (job):

1. Manual, when the user himself has to click the Stop button at the execution console or toolbar.
2. According to the properties of each task - each copy of each task is executed as many times as specified in its properties.
3. By time - all tasks will be running at least for the number of seconds specified by the user. The control precision is about 0.5 seconds for this method.
4. By the overall number of executed iterations. A project is finished if the overall number of iterations for all copies (threads) of all tasks exceeds the specified value.
5. By the number of times each task is executed. A project is finished when each copy (thread) of each task is executed the specified number of times.
6. By the number of times each thread is executed. A project is finished when thread copy of each task is executed at least the specified number of times.^*

^* - this method is not compatible with 'sequential' and 'by group' modes.

All or checked threads can be paused. To continue execution use the same Pause/Continue button.
