How to run parallel thread groups on various slave nodes using JMeter?

Question

I have 3 thread groups in my test plan and I have 3 slave nodes (remote servers). I would like to run all these thread groups in parallel but each one on a specific slave node.

+ Test Plan 
   + Thread Group A - (192.168.1.1)
       - HTTP Request Defaults
       - Cookie Manager
       + HTTP Request X
   + Thread Group B - (192.168.1.2)
       - HTTP Request Defaults
       - Cookie Manager
       + HTTP Request Y
   + Thread Group C - (192.168.1.3)
       - HTTP Request Defaults
       - Cookie Manager
       + HTTP Request Z

Example:

Thread Group A on 192.168.1.1

Thread Group B on 192.168.1.2

Thread Group C on 192.168.1.3

Anyone has any idea if something like this is possible on JMeter or not? Any suggestion or thoughts would be really appreciated.

Go for If Controller and __machineIP() function combination

For example below setup will mean that the HTTP Request 1 will be executed only on machine with IP address of 192.168.1.1 and HTTP Request 2 will be run on all machines:

If you need text version of the condition expression:

${__jexl3("${__machineIP()}" == "192.168.1.1",)}

however you should be able to easily generate you own one using Functions Helper Dialog
