Dr. Ike Nassi is a Computer Scientist. He is an IEEE Fellow (citation: "for leadership in parallel and distributed systems and adaptive systems"), a Fellow of the IEEE Computer Society, as well as a Senior Life Member.  He is also a Life Member of the Association for Computing Machinery.  He is named on over 35 patents (see below) with other patents in progress.

He was the founder, chairman and CTO of TidalScale, a software  pioneer which has developed a software architecture called distributed virtual machines.  TidalScale's software, which sits below an operating system and above bare metal commodity hardware, aggregates commodity servers together to create a  single virtual server to address challenging Big Data problems for in-memory SQL and NoSQL databases, large-scale analytics, simulation, and computational genomics.  Because resources are virtual, they can migrate from node to node in the cluster and can be dynamically added and removed, allowing for hardware scalability, reliability, and resiliency.  Instead of requiring application software to be customized for a specific computing environment, TidalScale's software allows a customer to tailor the computing environment to the needs of application software with no modification required.  HPE  acquired TidalScale's products and intellectual property in December 2022.

He has been an Adjunct Professor at the Baskin School of Engineering, UC Santa Cruz for over a decade.  He's a member of two research labs: Languages Systems and Data and the Storage and  Systems Research Center (a.k.a. Center for Research in Systems and Software).

He is also a founding trustee of the Computer History Museum.  He has served on its Executive Committee, its Nomination and Governance Committee, and has been the chair of the CHM Fellows Selection Committee for 16 years. The Computer History Museum published his oral history.  A transcript is available.

In the past, he was an Executive Vice President and Chief Scientist at SAP AG. At SAP, he and his group explored advanced new enterprise technologies and applications for use in multinational corporate environments. He started SAP's Global Business Incubator, whose goal is to start up new businesses within SAP. He also started and operated the SAP Sponsored Academic Research Program, over five years supporting a hundred sponsored research projects in universities in several countries.  His most recent area of interest at SAP was in designing and building "Enterprise Supercomputers" for Big Data applications.

During 2009-2010 he was in residence as a visiting scientist at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL), where he is also currently a research affiliate.

He started one of the first mesh networking companies, called Firetide.  Earlier, he had been Vice President of Product Development and Operations and Chief Technology Officer at InfoGear Technology Corporation which was acquired by Cisco June 2000.  InfoGear developed an internet-connected intelligent phone, called the iPhone in 1997 with built in web browsing and email. 

Prior to joining InfoGear, he was a Senior Vice President and a Corporate Officer at Apple Computer, where he led its AppleSoft Division until November 1996. At Apple he was responsible for all system software, including MacOS.  His three main contributions at Apple were the introduction of the Mach microkernel, which is now used in every iPhone, iPad, and Macintosh, and a study that led to an investment in Acorn RISC Machines, now ARM.  ARM processors are now used in all iPhone, Macs, and iPads, as well as most other mobile devices. He also testified before the U.S. Congress on the
Emerging Telecommunications Act of 1991, supporting the reservation of public access radio spectrum for what we now think of as 802.11 WiFi.

Prior to working at Apple he helped start Encore Computer Corporation, a pioneer in the design and development of shared memory multiprocessors.  Under a DARPA research contract, he and his team developed the idea and an implementation of hierarchically organized distributed cache coherent shared memory multiprocessors.

Before that worked at Visual Technology, Digital Equipment Corporation where he worked on the VAX superminicomputer and SofTech Inc where he worked on software for the F-16 and the B-1 aircraft.

He has served the Federal government in several capacities.  He holds a Certificate for Distinguished Service from the U.S. Department of Defense for his design work on the programming language Ada.  He served for six years as a member of Defense Advanced Research Projects Agency's (DARPA) Information Systems and Technology group, advising DARPA on information science research priorities, for which he was awarded another Certificate for Distinguished Service.

Throughout his career, he has been involved simultaneously in industry and Academia.  He has been a visiting scholar Stanford University, twice a research affiliate at the Massachusetts Institute of Technology and a visiting scholar in Electrical Engineering and Computer Science at the University of California at Berkeley. Early in his career, he taught Computer Science at Boston University.

He was on the advisory board of the School of Software and Microelectronics, Peking University, the advisory board of the Department of Electrical Engineering and Computer Science of Northwestern University and the Center for Wireless & Information Technology at Stony Brook University.

He is also a founding member of the IEEE Computer Society's Industry Advisory Board.


 
Previously, he served on the Advisory board of Viewpoints Research (founded by Alan Kay) and he served as a member of two women's advocacy groups: he was a member of the Board of Trustees of the Anita Borg Institute for Women and Technology, and an advisor to Watermark.

Here is a list of his publications and speaking engagements.

During the pandemic, he wrote some software to manage Desktop Images (i.e. Wallpaper) on a Mac.  It is written using Keyboard Maestro, and can be downloaded here.  Recently he wrote an extension to Apple Mail for efficiently filing emails into selected mailboxes. Download it here.  


Secure.IO recently published a podcast interview.


Dr. Nassi holds an M.S. and a Ph.D. in Computer Science and a B.S. in Mathematics from Stony Brook University. Stony Brook's Computer Science Department published this announcement.  In 2008 he completed a global leadership development program at INSEAD.
