Extremely new to PBS Pro and to the world of job scheduling. I’m looking for something along the lines of a get started guide that includes **installation** and some sort of **demo** dummy system. Something that tells me how to setup a node or two and run a dummy job on them. _quick question to get my head around_ **Q1**. From what I’ve understood PBS Pro should allow me to submit a job to any of my (ex:10) machines depending on availability and machine load? _now to the installation & demo dummy I’m looking for_ So far I’ve found the installation [https://github.com/PBSPro/pbspro/blob/master/INSTALL](https://github.com/PBSPro/pbspro/blob/master/INSTALL) Also found this which looks like it has a dummy job [https://www.webmo.net/support/pbs.html](https://www.webmo.net/support/pbs.html) **Q2**. Perhaps that’s all there is to it? I was thinking something a little more “complex” w/ nodes and running a job depending on load (I guess if another job is currently running or high cpu loads - docker use case?) ---

Hi @aanderr Thank you for your interest in PBS Professional - the best approach is to create a VM running CentOS 7 using hypervisors ( VirtualBox or VMware) - make sure to turn off the firewalls , selinux , iptables ( reboot the system(VM) after making any changes) - give it a hostname and static IP address , so that everytime it boots up it gets the same IP, populate the same in the /etc/hosts (if there are 1 or more nodes all the nodes should have static IP / hostname and should be populated in the /etc/hosts of all the nodes of the PBS complex) - here we are installing all in one PBS complex, if you have 1 or more nodes, then you would need to setup common home directory and passwordless ssh for all the users , with stricthostchecking disabled + steps mentioned above - create a user account called “pbsdata” with some password - Download pre-compiled PBS Pro rpm’s for CentOS 7 from this link [https://www.pbspro.org/Download.aspx#download](https://www.pbspro.org/Download.aspx#download) - Install the required dependencies ( [https://github.com/PBSPro/pbspro/blob/master/INSTALL](https://github.com/PBSPro/pbspro/blob/master/INSTALL) ) **yum install -y expat libedit postgresql-server postgresql-contrib python3 \*\* sendmail sudo tcl tk libical** - as root unzip the package and yum install pbspro-server\*rpm - edit /etc/pbs.conf and update PBS\_START\_MOM=1 ( it will be PBS\_START\_MOM=0 ) /etc/init.d/pbs start - source /etc/profile.d/pbs.sh - qmgr -c ‘s s job\_history\_enable=true’ qmgr -c “s s flatuid=true” qmgr -c “create queue workq queue\_type=e, started=t, enabled=t” qmgr -c “set server default\_queue=workq” qmgr -c “create node pbsserver” # e.g., pbsserver is the hostname of the compute node we are adding - su - pbsdata and submit a sleep job as below qsub – /bin/sleep 100 qstat -answ1 # to monitor - Documents at this link should be able to help you with the rest [Altair Product Documentation - Altair Community](https://www.altair.com/pbs-works-documentation/) Answer to your queries: > [@aanderr](#): > > **Q1**. From what I’ve understood PBS Pro should allow me to submit a job to any of my (ex:10) machines depending on availability and machine load? Yes. PBS Professional will schedule your jobs based on the resources requested for your job and resource availability. If you have 1 node with 10 cores and 100GB memory and no jobs in the system, then - if you submit a job requesting 6 cores and 60GB memory , then the job will be run - if you submit a job requesting 5 cores and 40GB memory , then the job will be queued - if you submit a job with 2 cores 20GB memory, then job will run - if you submit a job with 2 cores 20GB memory , then the job will run > [@aanderr](#): > > _now to the installation & demo dummy I’m looking for_ > So far I’ve found the installation [https://github.com/PBSPro/pbspro/blob/master/INSTALL](https://github.com/PBSPro/pbspro/blob/master/INSTALL) > Also found this which looks like it has a dummy job [Installing Torque 6.0.1 on CentOS 7](https://www.webmo.net/support/pbs.html) If you are comfortable follow the above instruction guide.

I was thinking something a little more “complex” w/ nodes and running a job depending on load (I guess if another job is currently running or high cpu loads - docker use case?) Sure , this can be done. Please check the below section from this guide : [https://www.altair.com/pdfs/pbsworks/PBS19.2.3\_BigBook.pdf](https://www.altair.com/pdfs/pbsworks/PBS19.2.3_BigBook.pdf) 4.9.9.6.i Attributes and Parameters Affecting Cycle Harvesting Based on Load Average Hope this helps. ---

Hi @adarsh > [@adarsh](#): > > Hope this helps. This definitely helps a lot! Thank you 🙂 I installed _CentOS 8_ instead as I begun the installation before you replied. Is _CentOS 7_ a requirement for _PBS Pro_ to work? I’m using [this kernel version](https://centos.pkgs.org/8/centos-baseos-x86_64/kernel-4.18.0-147.el8.x86_64.rpm.html) ---

> [@aanderr](#): > > Is _CentOS 7_ a requirement for _PBS Pro_ to work? It is not a requirement, you can compile the PBS Pro OSS source code to the operating system of your choice (please check this link [https://github.com/PBSPro/pbspro/blob/master/INSTALL](https://github.com/PBSPro/pbspro/blob/master/INSTALL) ). However, the pre-compiled installers/rpm are readily made available for CentOS7 and OpenSuse 15. This will get you going with a testbed ASAP. Otherwise, you would have to spend some time in compiling the sources. ---
