The U.S. government regulates the export and reexport of Computers based on the Adjusted Peak Performance (APP) of the computer.

APP is measured in Weighted Teraflops (WT).

Computers with APP exceeding 0.75 weighted Teraflops (WT) are called High Performance Computers (HPC's) and are subject to stricter U.S. export controls.

Controls on HPC Exports

For HPC exports and reexports, the U.S. Government has divided the world into three tier groups based on U.S. national security and foreign policy interests.

Each country tier group has a maximum APP limit.

Tier Group	APP Maximum Limit
1	No maximum limit
3	0.75 WT Export Licence required over 0.75 WT.
4	Restricted Countries Export Licence required
