A computer-controlled coordinate mea- 

 suring machine determines the exact 

 dimensions of a precision-machined 

 stainless steel part. NIST researchers 

 use this and similar instruments to 

 devise ways to improve machine tool 

 performance. 



NIST participates in four components of the HPCC 

 Program: 



HPCS: Performance Measurement of Scalable 

 Systems 



NIST develops instrumentation and methiodology for 

 performance measurement of hiighi performance net- 

 works and massively parallel computer systems. 

 Emphasis is on the use of low-perturbation data capture 

 hardware and simplified software-based approaches to 

 performance characterization. 



NREN: Networking and Information Infrastructure 



NIST supports and coordinates the development of 

 standards within the Federal government to provide 

 interoperability, common user interfaces to systems, and 

 enhanced security. NIST works with other agencies to 

 promote open system standards to aid in the commer- 

 cialization of technology by U.S. industry. NIST pro- 

 motes the development of communications infrastruc- 

 ture and the use of the Internet through information 

 technology research, development, and related activities 

 to enhance basic communications capabilities. 



ASIA: Application Systems and Software 

 Technology 



NIST develops algorithms and generic software for 

 advanced scientific, engineering, and manufacturing 

 applications. Common elements and techniques are 

 encapsulated in software libraries to promote ease of 

 use and application portability. NIST's Guide to 

 Available Mathematical Software (GAMS) provides 

 industry and the public with improved electronic access 

 to reusable software. 



IITA: Systems Integration for Manufacturing 

 Applications 



NIST will build upon its experience in information tech- 

 nology and manufacturing engineering to accelerate the 

 application of high performance computing and commu- 

 nications technology to manufacturing environments.
