[gem5-users] Why to modify Hostname in dist-gem5

[Boyang Xu]

Hi all,

There is a command "*/bin/hostname node${MY_RANK}*" in the file
*boot.easy.ckpt.rcS*, but I do not know its function. I tried to delete
this command and then took a checkpoint with the script. It works!
Moreover, I also restored from this checkpoint and run bench by dist-gem5.
However, it is unable to find the real reason of modifying Hostname by
Google, so I guess that the reason is to set DNS. Should I set DNS when
using dist-gem5? Is there another way to set DNS in dist-gem5?
Any suggestion and help on this question is welcomed. Thanks a lot!

Hi Boyang,

dist-gem5 defines a unique hostname for each simulated system as a convenience for the user. It is not obligatory, you can use IP addresses directly instead of hostnames. dist-gem5 does not require DNS.
