iMac 27" with 16 GB Ram, Intel Core i7, MacOS 10.14 is very slow. On restart noticed on Activity Monitor that the atsd process is using 100% CPU and now can't launch any programs. Tried resetting PRAM and SMC with no difference. What is the atsd process anyway?

Anyone know?
It's part of the OS's font management system. Specifically, a function within ATS.framework at this location:
/System/Library/Frameworks/ApplicationServices.framework/Frameworks/ATS.framework/Support/atsd
That it won't release suggests possible corrupt fonts, a corrupt Font Book database, both, or other related issue.
For something simple to try, open Font Book and run the menu command, Restore Standard Fonts, then restart the Mac.

Thank you, this was very useful knowing this was a font issue. Even though the Restore Standard Fonts didn't work through Font Book I was able to clear the cache with the following terminal commands and restart my computer:
sudo atsutil databases -remove
Then run
atsutil server -shutdown
atsutil server -ping
Hopefully, the extra steps will do it.
Yes, clearing the cache did work.
Excellent. 🙂
atsd process in Activity Monitor? What is it?
