Install two instances of condor in two seperate directories on your machine using condor_config using installation procedure detailed in the manual.

In this guide, condor1 will be a central manager,submit node (COLLECTOR, MASTER, NEGOTIATOR, SCHEDD). condor2 (MASTER, STARTD) will be a execute only node. Configure each of these instances independently.

In two seperate shells, source each of the shell files in the release directory of condor1 and condor2, respectively.

{code}
$ source condor.sh
{endcode}

In each of the condor_config.local (or just condor_config) files set the Lock to different values for each instance.

{code}LOCK = /tmp/condor-lock.0.317763962390931 %in condor1's config

LOCK = /tmp/condor-lock.0.317763456546765 %in condor2's config{endcode}

In condor2's local config file, set

{code}COLLECTOR_HOST = {mycomputer} {endcode}

where mycomputer is your machine's name.

In condor1's local config file, ensure that COLLECTOR_HOST is set appropriately.

{code}COLLECTOR_HOST = $(FULL_HOSTNAME){endcode}

This links condor2 to the collector of condor1.

Both condor instances should now be ready to start and run together.
