Introduction: ---------------- 2.1 Provide a paragraph introduction to your use case. Background to the project is another alternative. (E.g. 100 words). ... 2.2 Is there a URL with more information about the project ? ... 3. Use Case to Motivate Functionality Within a Simple API: ---------------------------------------------------------- Provide a scenario description to explain customers' needs. E.g. "move a file from A to B," "start a job." Please include figures if possible. If your use case requires multiple components of functionality, please provide separate descriptions for each component, bullet points of 50 words per functionality are acceptable. ... 4. Customers: ------------- Describe customers of this use case and their needs. In particular, where and how the use case occurs "in nature" and for whom it occurs. E.g. max 40 words ... 5. Involved Resources: ---------------------- 5.1 List all the resources needed: e.g. what hardware, data, software might be involved. ... 5.2 Are these resources geographically distributed? ... 5.3 How many resources are involved in the use case? E.g. how many remote tasks are executing at the same time? ... 5.4 Describe your codes and tools: what sort of license is available, e.g. open or closed source license; what sort of third party tools and libraries do you use, and what is their availablility; do you regularly work from source code, or use pre-compiled applications; what languages are your applications developed in (if relevant), e.g. Fortran, C, C++, Java, Perl, or Python. ... 5.5 What information sources do you require, e.g. certificate authorities, or registries. ... 5.6 Do you use any resources other than traditional compute or data resources, e.g. telescopes, microscopes, medical imaging instruments. ... 5.7 Please link all the above back to the functionalities described in the use case section where possible. ... 5.8 How often is your application used on the grid or grid-like systems? [ ] Exclusively [ ] Often (say 50-50) [ ] Ocassionally on the grid, but mostly stand-alone [ ] Not at all yet, but the plan is to. 6. Environment: --------------- Provide a description of the environment your scenario runs in, for example the languages used, the tool-sets used, and the user environments (e.g. shell, scripting language, or portal). ... 7. How the resources are selected: ---------------------------------- 7.1 Which resources are selected by users, which are inherent in the application, and which are chosen by system administrators, or by other means? E.g. who is specifying the architecture and memory to run the remote tasks? ... 7.2 How are the resources selected? E.g. by OS, by CPU power, by memory, don't care, by cost, frequency of availability of information, size of datasets? ... 7.3 Are the resource requirements dynamic or static? ... 8. Security Considerations: --------------------------- 8.1 What things are sensitive in this scenario: executable code, data, computer hardware? I.e. at what level are security measures used to determine access, if any? ... 8.2 Do you have any existing security framework, e.g. Kerberos 5, Unicore, GSI, SSH, smartcards? ... 8.3 What are your security needs: authentication, authorisation, message protection, data protection, anonymisation, audit trail, or others? ... 8.4 What are the most important issues which would simplify your security solution? Simple API, simple deployment, integration with commodity technologies. ... 9. Scalability: --------------- What are the things which are important to scalability and to what scale - compute resources, data, networks ? ... 10. Performance Considerations: ------------------------------- Explain any relevant performance considerations of the use case. ... 11. Grid Technologies currently used: ------------------------------------- If you are currently using or developing this scenario, which grid technologies are you using or considering? ... 12. What Would You Like an API to Look Like? -------------------------------------------- Suggest some functions and their prototypes which you would like in an API which would support your scenario. ... 13. References: --------------- List references for further reading. ... --------------------------------------------------------------------
