The Art of Preparing OSv Packages
The third MIKELANGELO face-to-face meeting took place on 8th and 9th of September 2015 in the Swabian metropolis of Stuttgart. A surprising amount of greenery gives the city its unique character. (University of Stuttgart) kindly hosted the meeting at their premises and also took the more-than-interested group of MIKELANGELO people into their major machine rooms. In the photo below you can see the MIKELANGELO team in front of one of the fastest computers in the world.

The main objective of the meeting was to synchronise partners after the summer break and to ensure the technical progress is well-communicated and understood between the partners. A general understanding of all the objectives of the project, the technical work done, is crucial at this point - we are to deliver a large number of reports at the end of the year. These reports will reference all aspects of MIKELANGELO’s technology stack.
The technical discussions at the meeting have proven the immense progress made during the summer. The work on the RDMA module on the host is completed and the focus is now shifting to the guest operating system (OSv). OSv is improving in terms of pure efficiency and compatibility and also in terms of novel computing paradigms, which are to be showcased at the first review. Research on inter-VM security is resulting in the first conceptual and practical cases - stealing of encryption keys from VMs, using a rogue VM. sKVM, which is our modification of KVM, is progressing with the introduction of IOcm, which allows to scale the number of IO cores in KVM dynamically.
Our use-cases are being developed by leveraging all of Mikelangelo’s technology stack. The use cases have reached a state of initial baseline measurements. You can read about the details in the respective reports. Currently the aerodynamics use case with OpenFOAM has progressed most. We will provide some more information about this use case in one of our next blog posts. Finally, given the plethora of developed components, we are thinking integration, evaluation, validation - the latter two project phases haven’t officially started yet, but need to be included even at this stage. The integration of a holistic continuous integration system will be one of the next goals of the project.
To wrap up: big thanks to HLRS for hosting the event and just stay tuned - big things coming up, all released under friendly open-source licensing models.
