Joefon Jann Named a Lifetime Achiever by Marquis Who’s Who
Ms. Jann has been endorsed by Marquis Who’s Who as a leader in the computer science industry
OSSINING, NY, July 26, 2017, Marquis Who’s Who, the world’s premier publisher of biographical profiles, is proud to name Joefon Jann a Lifetime Achiever. An accomplished listee, Ms. Jann celebrates many years’ experience in her professional network, and has been noted for achievements, leadership qualities, and the credentials and successes she has accrued in her field. As in all Marquis Who’s Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.
As a distinguished computer engineer with IBM at the T.J. Watson Research Center in New York, Ms. Jann has devoted over 4 decades of passion, patience and perseverance to reach the top of her industry. Her most notable technical contributions include the co-invention of DLPAR (Dynamic Logical Partitioning) for POWER servers, which is also featured in the Encyclopedia for Parallel Computing; the modeling of MPP workloads (the Jann97 Model for Parallel Workloads); and numerous technologies that are being used for improving the PowerVM virtual server environments and the AIX operating system, particularly in the areas of resiliency, performance, security and consumability. Most celebrated of all, she was the systems person that ran the IBM Deep Blue chess machine for more than 2 years – in particular, the systems hardware and software upgrades she made for the 2nd chess match was an important factor for Deep Blue winning over the human chess champion Garry Kasparov in the second match in 1997. Ms. Jann hopes that her example inspires more women to become involved with computer science, and views computer programming as just another language to be learned.
Ms. Jann was born in Hong Kong and arrived in America in 1967. She received a full scholarship from Wellesley College where she obtained a B.A. degree in Mathematics, minoring in Physics. She then received a M.A. degree in Mathematics from CUNY, and a M.S. degree in Computer Science from Columbia University. Ms. Jann was an adjunct lecturer of mathematics at Lehman College for 3 years, and worked as a technical staff member at the Network Analysis Corporation in Glen Cove, NY for 1 year, before joining the IBM Systems Division headquarters in Harrison NY, as an APL programmer. Ms. Jann then joined the IBM NY Banking Branch Office as a Systems Engineer, rising through the ranks to become a NY Area Systems Specialist. She then became a technical staff member of the IBM Mathematical Analysis and Computation Center in NY.
In 1989, Ms. Jann joined the IBM T.J. Watson Research Center in Yorktown Heights, NY, the laboratory that developed the Deep Blue chess-playing computer, and many other even more significant game-changing computers and technologies in the world. Ms. Jann has been a Distinguished Engineer at IBM since 2007. She has 44 patents, published over 33 papers/book-chapters, a book forward, a paper in the “Encyclopedia of Parallel Computing”, and two of her papers have won best-paper awards. She has published a wealth of research materials spanning linear algebra programming, to systems software, to automated diagnosis of software crashes. Ms. Jann is a Senior member of the IEEE (Institute of Electrical & Electronics Engineers), member of IEEE-WIE (Women-In-Engineering) Society, and member of ACM, and SWE.
In the past, for her achievements in computer science and her pioneering role for women in the sciences, Ms. Jann was selected for inclusion in the 2001 volume of Who’s Who in the World, and in the 2002 volume of Who’s Who in America.
In recognition of outstanding contributions to her profession and the Marquis Who’s Who community, Ms. Jann has been featured on the Marquis Who’s Who Lifetime Achievers website. Please visit www.ltachievers.com for more information about this honor.
