Hinweis der Redaktion
- Fire facilities
- Created/operated/maintained via research projects , EU funding
- 17 core partners 4 year duration
- Resource discovery: Finding available resources across all facilities, and acquiring the necessary information to match required specifications. Resource requirements: Specification of the resources required during the experiment, including compute, network, storage and software libraries. Resource reservation: Allocation of a time slot in which exclusive access and control of particular resources is granted. Resource provisioning Direct (API): Instantiation of specific resources directly through the facility API, being the responsibility of the experimenter to select individual resources. Orchestrated: Instantiation of resources through a functional component, which automatically chooses resources that best fit the experimenter’s requirements. Experiment control: Control of resource behavior during experiment execution, involving actions to query and modify resource state, and their correct sequencing. Monitoring Facility monitoring: Instrumentation of resources to supervise the behavior and performance of facilities allow system administrators or first level support operators to verify that facilities are performing correctly. Infrastructure monitoring: Instrumentation of resources to collect data on the behavior and performance of services, technologies, and protocols to obtain measurements in the context of a concrete experiment. Experiment measuring: Collection of experiment data generated by frameworks or services that the experimenter can deploy on its own. Permanent storage: Storage of experiment related information beyond the experiment lifetime, such as experiment description, disk images and measurements. Resource release: Release of experiment resources after deletion or expiration the experiment.
- In this example an experimenter has developed a mechanism to automatically create a wifi mesh network (multi-hop network). The experimenter wants to test this at a larger scale, hoping to proof that the new solution can easily forward multiple streams at the same time without sacrificing any performance.
- As mentioned in the previous slide, there are 3 types of experimenter tools supported, and for each of them the experimenter has several options to choose from because we adopted 3 APIs in the Fed4FIRE architecture. For resource discovery, reservation and provisioning, the experimenter can choose to use the Fed4FIRE portal, Flack, Omni and SFI. All these tools use the SFA interface to talk to the specific testbed management components (called Aggregate Managers). For Experiment control, the experimenter can run its own instance of an experiment controller. This can be the OMF6 Experiment Controller, or NEPI. The user can also directly log in on the nodes using its local SSH client, and perform experiment control actions manually using the console on the resource. For measurement and monitoring, the experimenter can use several OML tools: filters, persistence tools (store in SQL database) and visualization tools. In case of experiment measurement, these tools will use OML streams that are directly originating from the OML measurement library component that is deployed on the resource. For facility and infrastructure monitoring, the testbed will wrap its existing monitoring infrastructure (being Nagios, Zabbix or Collectd) in an OML stream, which will be used by the OML experimenter tools. To support all these tools, it is required that testbeds expose their management software through the SFA interface, that they deploy OMF6 experiment contorl on their testbed, and that they provide one of the mentioned monitoring frameworks and wrap its output in OML streams. On the resources three agents have to be deployed: an OMF resource controller, an OML measurement library and the appropriate monitoring agent that corresponds with their adopted monitor framework.

- Demo jfed tool
- The problem is that there are different testbeds with each their management software, Experiment description : FULL description of entire configuration + FLOW of experiment + measurements definition -> Easier to re-run experiments under different environment + show scientific relevance by including entire description of the experiment + easier to compare results!
- Through this open call the project opens up the FORGE platform to volunteers from the learning community and elsewhere, who want to exploit FIRE facilities for educational purposes and contribute to the FORGE ecosystem. Within the call the project solicits proposals for the development (or use) of experiment-driven courses and offers the chance to educational institutions to include these innovative courses to their curricula. FORGE is seeking contributions and new developments of educational material within the FORGE platform and tools.
- The expected types of participants span among educational or research institutions, universities, individuals, small/medium/large enterprises, and in general anyone interested in bringing the worlds of FIRE and eLearning together. All proposals shall be eligible and may be accepted, provided that they foresee the use of FORGE tools and FIRE facilities within the implementation of the suggested courses.
- The FORGE project launches an Open Call as continuous open access to the FORGE tools, meaning that no strict procedures for proposal submission and evaluation will be applied. The call offers free access to the FORGE tools and processes. The open call will apply a fast submission process based on a simple proposal template. In addition, the collaboration of successful participants with the FORGE project will be formalised with a lean Memorandum of Understanding (MoU); therefore the administrative burden for proposers is limited, since there will be no Grant Agreement, no Consortium Agreement and no official deliverables. The FORGE consortium will provide support to the interested users throughout the development of their courses, covering guided training and technical assistance. Moreover, the participants will be acknowledged as associate partners and will receive wide recognition and high visibility through the project’s website. Participants from successful proposals within this call will not receive EC funding and will not become official partners in the FORGE project.
- What types of proposals are expected? Is the call addressed only to developers? Whether you are an educator, learner, developer or provider, many different types of proposals may be submitted for the FORGE Open Call, an indicative, non-exhaustive list of which is presented hereafter: Deployment (as-is) of an existing FORGE course (either one of the prototype courses that have been developed by the FORGE consortium or an external course that will be developed within the Open Call process by an external user) in the context of a real-time course offered within the curriculum of the proposing institution(s); Transformation of a traditional course to an experiment-driven course; Design and development of a new lab course, following the FORGE methodology; Further development and extension of a FORGE course; Creation of interactive educational material (e.g. editing an existing course and creation of an eBook) based on the FORGE approach; Development of new widgets and/or FIRE Adapters; Offering of a testbed for remote experimentation; Any combination of the above.
- In order to be able to provide optimal support to the participants and facilitate the implementation of proposals, a cut off-date for submission of proposals is set after the announcement of the call, at 15th May 2015. Depending on the interest expressed until then, the call may be extended into consecutive phases of submission and implementation of proposals. In that case, the stages of implementation of proposals and evaluation of work may be overlapping. Participants will be able to submit their proposals at any time after the official announcement of the call. However, proposals submitted after the first cut-off date (or any cut-off dates that will be set for the consecutive submission phases) will be taken into account for the next round of proposals submission and implementation.
- Following the open call announcement, all interested parties are welcome to submit their proposals for developing lessons and lab courses using FORGE tools together with FIRE facilities. Proposals will be submitted in a single stage, by completing a very simple application form that is available at the Open Call page of the project website (http://ict-forge.eu/opencall/). The proposals must consist of two parts, Part A and Part B: Part A provides the administrative information about the proposal and the applicants. The information requested includes characteristics of the applicants (organization profile and expertise) and contact details. Part B is the description of the content of the proposed work. Applicants are advised to follow this structure when describing their proposals. The subsections included in this part intend to highlight those aspects that support the objective of the call and the goals of the project in general. Part B covers, among other things, the concept and objectives of the proposed work, the implementation details and the expected outcome and impact of the proposed work. Proposals must be submitted in English, at the following address: opencall@ict-forge.eu An acknowledgement of receipt will be emailed to the email address of the person identified as responsible in the submitted proposal as soon as possible after the FORGE consortium receives the proposal. Participants will be able to submit their proposals at any time after the official announcement of the call. However, proposals submitted after the first cut-off date (or any cut-off dates that will be set for the consecutive submission phases) will be taken into account for the next round of proposals submission and implementation.
- All proposals shall be eligible and may be accepted, provided that they foresee the use of FORGE tools and FIRE facilities within the implementation of the suggested courses. However, some additional criteria will be also taken into account for ranking the proposals into a priority list in terms of implementation and provided support. These criteria include: the use of FIRE facilities, the reach of the course and its dissemination aspect, the feasibility and sustainability of the course, the interactive elements it comprises, as well as the foreseen provided support by the FORGE consortium. In addition, proposals that foresee the deployment of the proposed course in the context of a real-time course offered within the curriculum of the proposers’ institutions will be given high priority. However, no scoring will be applied, since the process is not competitive and the open call is not funded.
- Support to participants prior submission: The FORGE consortium will be available and will provide support to all interested parties for any discussion or clarification of any aspect of the call or their planned scenario of exploitation of the FORGE tools and processes throughout the duration of the call. This will cover guided training, both on administrative and technical issues, as well as technical assistance. Potential proposers are strongly encouraged to discuss their ideas with the FORGE consortium prior to the submission of their proposal. Support to participants during implementation: The FORGE consortium will provide support to all participants and monitor the implementation of the lab courses. To that end, the consortium will provide the following to all interested parties participating to the open call for the development of their courses: Online documentation and supporting material (such as videos with instructions on how to use the FORGE tools and platform and other technical issues). This documentation will be available at the Open Call page of the project website (http://ict-forge.eu/opencall/) throughout the duration of the call and may be updated if necessary, according to the received inquiries. A permanent channel for submission of inquiries by e-mail, to the following address: opencall@ict-forge.eu. A Frequently Asked Questions (FAQ) section at the Open Call page of the project website (http://ict-forge.eu/opencall/), where the received inquiries and several clarifications will be published. Νew users and contributors will be supported by the FORGE consortium. All cases will be carefully examined and the FORGE consortium will provide the required technical assistance to the best of its ability, especially regarding implementation of new APIs, FIRE adapters, eLearning widgets or Learning Management System (LMS) integration
