Teradata AMPs are the parallel distributed storage and computing unit in a Teradata server. We can use HASHAMP function to calculate the total AMP count (virtual processors) in a Teradata system.
HASHAMP function
HASHAMP function returns the identification number of the primary AMP corresponding to the specified hash bucket number. If no hash bucket number is specified, HASHAMP returns one less than the maximum number of AMPs in the system.
Code snippet
SELECT HASHAMP()+1 AS "AMP Count"
