In the examples below replace the string ?????? with a host name of your choice.
The environment of a task running on a remote host can be different from that of a task running locally. It depends on how your system is set up. The head.h should already be using the correct PATH, to allow child commands to be used. If not add the following line into your head.h file before the call to ecflow_client –init > export PATH=$PATH:/usr/local/apps/ecflow/ |
REMOTE_HOST=?????? # change me ssh $USER@$REMOTE_HOST mkdir -p \$HOME/.ssh # if you are prompted for a password use your Training password that was provided cat $HOME/.ssh/id_rsa.pub || ssh-keygen -t rsa -b 2048 cat $HOME/.ssh/id_rsa.pub | ssh $USER@$REMOTE_HOST 'cat >> $HOME/.ssh/authorized_keys' |
Modify the family f5 so that all its tasks will run on another machine in the classroom.
# Definition of the suite test suite test edit ECF_INCLUDE "$HOME/course" edit ECF_HOME "$HOME/course" limit l1 2 family f5 edit HOST ?????? edit ECF_OUT /tmp/$USER edit ECF_JOB_CMD "ssh %HOST% 'mkdir -p %ECF_OUT%/%SUITE%/%FAMILY% && %ECF_JOB% > %ECF_JOBOUT% 2>&1 &'" inlimit l1 edit SLEEP 20 task t1 task t2 task t3 task t4 task t5 task t6 task t7 task t8 task t9 endfamily endsuite |
If your login shell is csh, you should define ECF_JOB_CMD as:
edit ECF_JOB_CMD "ssh %HOST% 'mkdir -p %ECF_OUT%/%SUITE%/%FAMILY%; %ECF_JOB% >& %ECF_JOBOUT%'" |
In python modify the function create_family_f5() created in the earlier page, to add HOST,ECF_OUT,ECF_LOGHOST,ECF_LOGPORT, and ECF_JOB_CMD:
import os from ecflow import Defs,Suite,Family,Task,Edit,Trigger,Complete,Event,Meter,Time,Day,Date,Label, \ RepeatString,RepeatInteger,RepeatDate,InLimit,Limit def create_family_f5() : return Family("f5", InLimit("l1"), Edit(SLEEP=20, HOST='?????', ECF_OUT = '/tmp/%s' % os.getenv("USER"), ECF_LOGHOST='%HOST%', ECF_LOGPORT='?????', # port=$((35000 + $(id -u))) run this on the command line ECF_JOB_CMD="ssh %HOST% 'mkdir -p %ECF_OUT%/%SUITE%/%FAMILY%; %ECF_JOB% > %ECF_JOBOUT% 2>&1 &'"), [ Task('t{}'.format(i)) for i in range(1,10) ] ) print("Creating suite definition") home = os.path.join(os.getenv("HOME"),"course") defs = Defs( Suite("test", Edit(ECF_INCLUDE=home,ECF_HOME=home), Limit("l1",2), create_family_f5())) print(defs) print("Checking job creation: .ecf -> .job0") print(defs.check_job_creation()) print("Checking trigger expressions") assert len(defs.check()) == 0,defs.check() print("Saving definition to file 'test.def'") defs.save_as_defs("test.def") |
We can view the output on the remote machine (class??) by using a log server.
This assumes you have defined variables ECF_LOGHOST and ECF_LOGPORT in your definition.
Launch the log server on a remote machine:
ssh $USER@class01 /usr/local/apps/ecflow/5.5.1/bin/ecflow_logserver.sh -d /tmp/$USER -m /tmp/$USER:/tmp/$USER |
