NEW POSIX® CERTIFICATION ADDRESSES 
PREDICTABILITY IN REALTIME COMPUTING SERVICES

PISCATAWAY, N.J., AND SAN FRANCISCO, CALIF., USA, 19 July 2005   The Open Group and IEEE have
introduced a POSIX® certification to aid predictability in operating system environments that
involve realtime services.  The certification is based on the criteria for bounded response times
in Application Profile PSE54, which is part of the IEEE 1003.13(TM)-2003 standard, and complements
the existing certification program for the base POSIX 1003.1(TM) standard.  

The new certification, "PSE54 Multipurpose Realtime 1003.13-2003 System", is offered under the
POSIX®: Certified by the IEEE and The Open Group Program.  The Open Group has begun accepting
registrations for PSE54 certification.  Certification through Jan.18, 2006 will involve a set of
interim conformance requirements.  Full conformance certification begins after this date.  Once
obtained, certification is renewed annually. 

PSE54 is one of four profiles in IEEE 1003.13 2003, "Standardized Application Environment Profile -
POSIX Realtime and Embedded Application Support (AEP)".  These profiles are aligned with the
current POSIX standard, IEEE 1003.1(TM)-2003, "Standard for Information Technology--Portable
Operating System Interface (POSIX)".     

"The predictable response times enabled by PSE54 are essential for time-critical military,
industrial and other computer system applications," says Andrew Josey, Director of Certification at
The Open Group.  "Certification to PSE54 is designed to give users confidence that the realtime
products they purchase work within the time constraints they need.  Beyond this, we may establish
certifications for the other three profiles in IEEE 1003.13, provided sponsors are found to support
the testing needed."    

POSIX certification is currently available for products that meet the requirements given in IEEE
1003.1(TM)-2003, "Standard for Information Technology--Portable Operating System Interface (POSIX)"
and the IEEE 1003.13-2003, "Standardized Application Environment Profile   POSIX Realtime and
Embedded Application Support (AEP)".  It is widely used in government, industry and elsewhere. The
POSIX®: Certified by the IEEE and The Open Group Program is voluntary and jointly administered by
the IEEE and The Open Group.  

Under the program, suppliers substantiate claims of conformance to POSIX, based on defined test
suites, so buyers gain assurance that products meet the standard and are warranted by the vendor to
do so.  POSIX certification complements those for other products that draw on the POSIX standard,
such as those for LSB®, the COE Platform and the UNIX® system.  

IEEE 1003.13 was developed by the IEEE Portable Applications Standards Committee and the
SSWG-Realtime Working Group and offers a set of profiles based on IEEE 1003.1, 2003 Edition.

About The Open Group 
The Open Group is a vendor-neutral and technology-neutral consortium, which drives the creation of
Boundaryless Information Flow(TM) that will enable access to integrated information within and
between enterprises based on open standards and global interoperability. The Open Group works with
customers, suppliers, consortia and other standard bodies. Its role is to capture, understand and
address current and emerging requirements, establish policies and share best practices; to
facilitate interoperability, develop consensus, and evolve and integrate specifications and open
source technologies; to offer a comprehensive set of services to enhance the operational efficiency
of consortia; and to operate the industry's premier certification service. Further information on
The Open Group can be found at http://www.opengroup.org.

About the IEEE Standards Association
The IEEE Standards Association, a globally recognized standards-setting body, develops consensus
standards through an open process that brings diverse parts of an industry together.  These
standards set specifications and procedures based on current scientific consensus.  The IEEE-SA has
a portfolio of more than 870 completed standards and more than 400 standards in development. For
information on IEEE-SA, see: http://standards.ieee.org/.  

About the IEEE
The IEEE has more than 360,000 members in approximately 150 countries. Through its members, the
organization is a leading authority on areas ranging from aerospace, computers and
telecommunications to biomedicine, electric power and consumer electronics. The IEEE produces
nearly 30 percent of the world's literature in the electrical and electronics engineering,
computing and control technology fields.  This nonprofit organization also sponsors or cosponsors
more than 300 technical conferences each year.  Additional information about the IEEE can be found
