sync_supers does not seem to be a CentOS binary, so I have no idea what it is doing.

See if ps -ef | grep sync_supers shows the path of the binary. If it shows something like /usr/bin/sync_supers, run rpm -qf /usr/bin/sync_supers to see which package owns that file (if any). If it's a script you can view the file with plain more /usr/bin/sync_supers, but if it's a binary, you can use strings /usr/bin/sync_supers instead. Replace /usr/bin in these commands with the actual path.

Are you perhaps running Drupal on your server?

Yes, my server running Drupal 7.
After I restarted the server the cpu ran normally, about 4 days later it came up.

There's a chance that you have been hacked through Drupal. See https://www.drupal.org/security

Without knowing details of that sync_supers process it's hard to tell for sure, though.
