Condor and Pegasus on ubuntu12.04

Single Node Condor and Pegasus on ubuntu12.04 

[STEP 1: Install Condor]

Download the latest version of HTCondor (native package) for Ubuntu 12.04 from the following URL. What I have downloaded is condor-8.1.6-247684-ubuntu_12.04_amd64.deb. The actual filename might change over time.

http://research.cs.wisc.edu/htcondor/downloads/

Install Condor using the following commands:

$ sudo dpkg -i condor-8.1.6-247684-ubuntu_12.04_amd64.deb$ sudo apt-get update$ sudo apt-get install -f$ sudo apt-get install chkconfig$ sudo chkconfig condor on$ sudo service condor start

Now we should have Condor up and running, and it should be automatically started when the system boots. Check into the status of Condor using the following commands:

$ condor_statusName               OpSys      Arch   State     Activity LoadAv Mem   ActvtyTimeslot1@ip-10-0-5-11 LINUX      X86_64 Unclaimed Benchmar  0.060 1862  0+00:00:04slot2@ip-10-0-5-11 LINUX      X86_64 Unclaimed Idle      0.000 1862  0+00:00:05slot3@ip-10-0-5-11 LINUX      X86_64 Unclaimed Idle      0.000 1862  0+00:00:06slot4@ip-10-0-5-11 LINUX      X86_64 Unclaimed Idle      0.000 1862  0+00:00:07                     Total Owner Claimed Unclaimed Matched Preempting Backfill        X86_64/LINUX     4     0       0         4       0          0        0               Total     4     0       0         4       0          0        0$ condor_q-- Submitter: ip-10-0-5-114.ec2.internal :  : ip-10-0-5-114.ec2.internal ID      OWNER            SUBMITTED     RUN_TIME ST PRI SIZE CMD               0 jobs; 0 completed, 0 removed, 0 idle, 0 running, 0 held, 0 suspended

[STEP 2: Install Pegasus]

Pegasus needs Java (1.6 or higher) and Python (2.4 or higher). Ubuntu 12.04 comes with Python 2.7 but not Java, so we will need to install Java first. Optionally Pegasus also needs Globus for grid support, we will take care of Globus later.

$ sudo apt-get install openjdk-7-jdk

Then we config the Pegasus repository and install Pegasus.

$ gpg --keyserver pgp.mit.edu --recv-keys 81C2A4AC$ gpg -a --export 81C2A4AC | sudo apt-key add -  

All the following line into /etc/apt/source.list:

deb http://download.pegasus.isi.edu/wms/download/debian wheezy main

Update the repository and install Pegasus:

$ sudo apt-get update$ sudo apt-get install pegasus

Now we should have Pegasus installed on the system. Check the installation with the following command. If you see similar output, congratulations!

$ pegasus-status(no matching jobs found in Condor Q)

Pegasus comes with some examples, we will use these example to test the installation further.

$ cd ~$ cp -r /usr/share/pegasus/examples .$ cd examples/hello-world$ lsdax-generator.py  hello.sh  pegasusrc  submit  world.sh

Run the hello-world example:

Check the status of the Pegasus jobs and Condor queue using the pegasus-statua and condor_q commands:

$ pegasus-statusSTAT  IN_STATE  JOB                                               Run      01:05  hello_world-0                                     Summary: 1 Condor job total (R:1)$ condor_q-- Submitter: ip-10-0-5-114.ec2.internal :  : ip-10-0-5-114.ec2.internal ID      OWNER            SUBMITTED     RUN_TIME ST PRI SIZE CMD                  1.0   ubuntu          6/24 10:34   0+00:01:28 R  0   0.0  pegasus-dagman -f 1 jobs; 0 completed, 0 removed, 0 idle, 1 running, 0 held, 0 suspended

Multi Node Condor and Pegasus on ubuntu12.04 

[STEP 1: Install Condor]

Similar to the previous tutorial, download the latest version of HTCondor (native package) for Ubuntu 12.04 from the following URL. What I have downloaded is condor-8.1.6-247684-ubuntu_12.04_amd64.deb. The actual filename might change over time.

http://research.cs.wisc.edu/htcondor/downloads/

Install Condor using the following commands:

$ sudo dpkg -i condor-8.1.6-247684-ubuntu_12.04_amd64.deb$ sudo apt-get update$ sudo apt-get install -f$ sudo apt-get install chkconfig$ sudo chkconfig condor on$ sudo service condor start

Now we should have Condor up and running, and it should be automatically started when the system boots. Check into the status of Condor using the following commands:

$ condor_statusName               OpSys      Arch   State     Activity LoadAv Mem   ActvtyTimeslot1@ip-10-0-5-11 LINUX      X86_64 Unclaimed Benchmar  0.060 1862  0+00:00:04slot2@ip-10-0-5-11 LINUX      X86_64 Unclaimed Idle      0.000 1862  0+00:00:05slot3@ip-10-0-5-11 LINUX      X86_64 Unclaimed Idle      0.000 1862  0+00:00:06slot4@ip-10-0-5-11 LINUX      X86_64 Unclaimed Idle      0.000 1862  0+00:00:07                     Total Owner Claimed Unclaimed Matched Preempting Backfill        X86_64/LINUX     4     0       0         4       0          0        0               Total     4     0       0         4       0          0        0$ condor_q-- Submitter: ip-10-0-5-114.ec2.internal :  : ip-10-0-5-114.ec2.internal ID      OWNER            SUBMITTED     RUN_TIME ST PRI SIZE CMD               0 jobs; 0 completed, 0 removed, 0 idle, 0 running, 0 held, 0 suspended

[STEP 2: Config Condor Master Node]

Use a text editor to open /etc/condor/condor_config, and add the following line to the end of the file:

ALLOW_WRITE = *

Then restart Condor with the following command:

$ sudo service condor restart

Also, find the IP address of the Master Node with the following command, you will need it to config theWorker Node.

[STEP 3: Config Condor Worker Node]

Now we go ahead to config the Worker Node. Use a text editor to open /etc/condor/condor_config.local, find the following line

CONDOR_HOST = $(FULL_HOSTNAME)

and update it with the IP address of the Master Node. Assuming that the IP address of the Master Node is 192.168.1.1, then this line should look like the following

CONDOR_HOST = 192.168.1.1

Then restart Condor using the following command:

$ sudo service condor restart

Now on both the Master Node and the Worker Node, we will be able to see both nodes. In the following example, both the Master Node and the Worker Node are c3.xlarge instances. Each of the c3.xlarge instance have 4 vCPU’s, so we are seeing 8 slots in the cluster.
