Practitioner's Guide to Adjusted Peak Performance: The Bureau of Industry and Security is pleased to provide a Practioner's Guide to Adjusted Peak Performance to aid in the calculation of the Weighted Teraflops (WT) values of high performance computers. This Guide has been prepared in conjunction with the Information Systems Technical Advisory Committee (ISTAC).

High Performance Computer Update: On April 24, 2006, the Bureau of Industry and Security (BIS) amended the Export Administration Regulations (EAR) to implement the Wassenaar Arrangement’s December 2005 agreement to revised the formula for calculating computer performance from Composite Theoretical Performance (CTP), measured in Millions of Theoretical Operations Per Second (MTOPS) to Adjusted Peak Performance (APP), measured in Weighted TeraFLOPS (Trillion Floating point Operations Per Second)(WT). This amendment also established new control levels in Category 4 of the Commerce Control List (CCL) expressed in WT. In addition, this amendment renamed License Exception CTP to License Exception APP (Adjusted Peak Performance) to correspond to the new formula. Pursuant to the Wassenaar Arrangement agreement, the control level for computers controlled for national security reasons is 0.75 WT. The amendment also moved Bulgaria from Computer Tier 3 to Computer Tier 1 effective June 3, 2006, removed High Performance Computer (XP) and Missile Technology (MT) controls from certain Export Control Classification Numbers (ECCNs) in Category 4 of the CCL, and removed the section of the EAR (section 742.12) dedicated to various requirements for high performance computers.

Licensing Tips

HPC Archives

This page is designed to serve as a licensing and policy navigation tool for exporters of high performance computers (HPCs) and components. HPC licensing and policy can be complex. We are providing the information linked to this page in order to help smooth the licensing process and to make the policy more transparent. We recommend that you review the documents in the order they appear in the right hand column, so that you may gain a more complete understanding of the licensing process. If you have additional questions about licensing requirements or HPC policy, please call the number listed below.
