Tasks can be logically grouped into
family‘s.
You can picture a suite as a hierarchical structure very similar to a unix
file system, where the families are the directories and the tasks are the files.
Like directories, families can themselves contain other families.
And like directories, there can be many tasks with the same name, as long as
they are in different families.
Unless you tell ecFlow where to find specific files, the default behaviour
is to expect the file structure to reflect the structure of the suite.
Ecf Script
In suite definition below we will create a family f1 with two tasks t1 and t2.
In this case you will have to create a directory $HOME/course/test/f1,
and move t1.ecf and t2.ecf into it.
Conversely, the ecFlow jobs and the outputs will be created in this directory.
Because we have moved the scripts to another directory, ecFlow will not find
the two included files
head.h and
tail.h one directory up from
the scripts.
We could modify the scripts to search the include file two directories up,
but this would be very cumbersome.
The solution is to define a special ecFlow
variable called
ECF_INCLUDEthat points to the directory containing the include files. See
pre-processingWhenever angled brackets are used, ecFlow first looks to see if ECF_INCLUDE
variable is specified. If the variable exists, it checks to see if file
%ECF_INCLUDE%/head.h exists, otherwise it looks for %ECF_HOME%/head.h
This has the added advantage that specific includes files can be placed under
ECF_INCLUDE, and includes file common to many tasks can placed in
We need to do the following changes to the
ecf script‘s.
from:
%include "../head.h"
echo "I am part of a suite that lives in %ECF_HOME%"
%include "../tail.h" |
to:
%include <head.h>
echo "I am part of a suite that lives in %ECF_HOME%"
%include <tail.h> |
suite‘s, family‘s and task‘s are called node‘s.
Text
# Definition of the suite test.
suite test
edit ECF_INCLUDE "$HOME/course" # replace '$HOME' with the path to your home directory
edit ECF_HOME "$HOME/course"
family f1
task t1
task t2
endfamily
endsuite |
Python
If you are using the Suite Definition API: Update $HOME/course/test.py
#!/usr/bin/env python2.7
import os
import ecflow
def create_family_f1():
f1 = ecflow.Family("f1" )
f1.add_task("t1")
f1.add_task("t2")
return f1
print "Creating suite definition"
defs = ecflow.Defs()
suite = defs.add_suite("test")
suite.add_variable("ECF_INCLUDE", os.path.join(os.getenv("HOME"), "course"))
suite.add_variable("ECF_HOME", os.path.join(os.getenv("HOME"), "course"))
suite.add_family( create_family_f1() )
print defs
print "Checking job creation: .ecf -> .job0"
print defs.check_job_creation()
print "Saving definition to file 'test.def'"
defs.save_as_defs("test.def")
The hierarchy is shown as a tree in ecflow_ui
What to do
- Update the suite definition
- Create the directories needed, move the ecf script‘s
- Edit the script to include head.h and tail.h from the
ECF_INCLUDE
directory. - Replace the suite
python: python test.py
python client.py
text: ecflow_client --suspend=/test ; ecflow_client --replace=/test test.def - View the suite in ecflow_ui , notice the tree structure. You may have to unfold test and f1 to see the tasks.
