In the early days of Grid computing, Olle Mulmo joined a (then small) team at Argonne National Laboratory, IL, where he contributed to the Globus Project and lead several external application integration efforts. After a move back to Sweden,

Mr. Mulmo worked as a Software Architect and Program Manager at a security software company, developing software for national-scale PKI infrastructures.

Globus started as a bottoms-up, proof-of-concept approach to provide a common middleware layer primarly for remote job submission to various supercomputers, and a platform-independent set of libraries that applications could use to easily port their applications and have it run on different hardware platforms. Globus v1.0 run on probably 10 different OSes, from Windows to Cray, and maintainance was a nightmare. A couple of years later, GT2 came. While several APIs and interfaces looked the same, the internals were to a large extent rewritten.

When industry and other external projects started to show interest in resuing components or building solutions on top of GT, it quickly became clear that the "proprietary", de-facto standards or protocol extensions that were in GT2 were not sufficient or adequate, and that we needed more and better toolkit-neutral standards in the grid community. This lead to to the shift towards the merging of the Grid and Web services communities, and we are in that transition still: we had a rather bumpy road the past two years with two architectural overhauls in GT3 and GT4. Things look really good now though, so hopefully that effort was worth it at the end of the day.

Security is one of the main focal points in the Globus toolkit. We have an impressive set of bright minds on the securit architecture team, but that is of course not enough: bugs in the software, correct deployment and configuration of the software, and vigilant users are factors you can never completely safeguard against.
