Consultanties 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
- Secure Lustre
- MERO/Colibri Object Storage System
- Enclosure Firmware
I introduced architecture and software development processes. I managed outsourcing relationships for software and was involved in the selection of oversearch design and manufacturing of hardware.
When it became apparent Xyratex was going to be acquired (by Seagate) I left the company.
SUN Microsysmstem, 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
- architecture of a unified approach to SUN storage
- 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, managed 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 project 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 about it. Sometimes I publish a refereed paper, and guide some 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.
