CONSULTANCY AS THOUGHT LEADER AND THINKING PARTNER
2018 European Processor Initiative (EPI): I assisted one of the partners in the EPI consortium with review of proposals and evaluation of critical technology.
2013- Square Kilometer Array (SKA) radio telescope: As a consultant to Cambridge University, I contributed to technical, vendor related, and process oriented aspects of engineering for the SKA.
2014 Department of Science and Technology (DST) South Africa: I evaluated proposals for the DST and assisted them brainstorming about critical initiatives. I brought new areas of focus to the annual CHPC conference.
2011 - 2013 Exascale I/O Workgroup: I led a discussion group which developed influential ideas.
2012-2014, EC Brussels: I served on the committee to create initial blueprints for the Horizon 2020 program’s HPC research initiatives.
As Senior Vice President I was a member of the CEO’s executive board and directed software engineering, in a team of some 300 engineers, across many products, including:
ClusterStor’s product line
Grid RAID for Lustre
MERO/Colibri Object Storage System
I introduced architecture and software development processes. I managed outsourcing relationships for software and was involved in the selection of overseas design and manufacturing of hardware.
When it became apparent Xyratex was going to be acquired (by Seagate) I left the company.
SUN MICROSYSTEMS, VICE PRESIDENT 2007-2008
While reporting to the Executive VP of Engineering (John Fowler) and working with the CEO (Jonathan Schwarz) I worked on strategic projects such as:
the integration of Cluster File Systems into SUN
designing a unified approach to the SUN storage portfolio
ports of products from Linux to Solaris and vice versa
In many of these projects I worked with Jeff Bonwick and Bill Moore. I visited many customers around the world and worked on proposals for HPC installations with Andreas Bechtolsheim. When it became apparent SUN was going to be acquired (by Oracle) I left the company.
CEO FOR 5 OF MY STARTUPS, (AND CTO FOR ONE).
I led the architecture of products, early customer relations, and technical marketing. I leveraged processes from Carnegie Mellon’s Software Engineering Institute. I was coached to gain executive skills, which became valuable as the company grew to around 130 people and 100 customers. I generally wrote white papers and course materials and delivered many technical lectures.
Academic 2015-: I interact with a few research groups on issues described on the work page. I give some 5 invited lectures annually, and frequently initiate discussions about open issues that have not received enough attention. I organize brainstorming meetings or small workshops. Sometimes I publish refereed papers, and supervise graduate students. I work both with academic and industry researchers.
Senior Systems Scientist 1996-2000: I took over leadership of the Coda project in the School of Computer Science at Carnegie Mellon University as a Senior Systems Faculty member. The project and one of my papers won an award, and the origins of two successful commercial products (InterMezzo and Lustre) were established.
Mathematician 1980-1996: I pursued an academic career until 1995. I published papers, had eight PhD students complete their thesis under me.
