repeat datelist YMD 20130101 20130102 20130103 20200101 20190101 |
Note |
---|
If repeat date, or repeat datelist are used in trigger expressions, they will use date arithmetic. |
Repeat with day/date
The behaviour of day/date attribute under a repeat has changed from ecflow 4.0. Take the example below.
In ecflow 4.0, if task t1 took longer than 1-hour task t2 would not run. (i.e. because we strayed over to the next day)
In ecflow 5.0, once the day monday is free on family f1, it stays free until the automatic re-queue caused by the parent repeat. The net effect being that task t2 will still run, even if we have strayed into Tuesday.

suite s1
family f
repeat integer rep 0 7
family f1
day monday
time 23:00
task t1
task t2
trigger t1 == complete
... |
Repeat increment
A repeat under a family node will only increment when all the child nodes are complete.
In the example above, once task t1, and t2 are complete, the repeat integer rep will increment to the next value.

# These can also be used in trigger expression.

Let us modify the suite definition file again

# Definition of the suite test.

edit ECF_INCLUDE "$HOME/course"
edit ECF_HOME "$HOME/course"

edit SLEEP 2
repeat string NAME a b c d e f

repeat integer VALUE 1 10
task t1
repeat date DATE 20101230 20110105

What to do
- Type in the changes
- Replace the suite definition
- How many times will /test/f4/f5/t1 run?
- In ecflow_ui , try to modify the values of a repeat
- Since we are using a 2-second delay, remember to use f5(refresh) to see the intermediate values. The default is to refresh every 60 seconds.
