If you have any further issues please let us know.
You could find the architecture and features of the compute nodes available by using the below command in login node:
Please find the screenshot, which shows the details of a specific compute node. Here you can see that this particular node is fpga node.
Similarly you will be able to find the details of all the compute nodes by using the pbsnodes command.
