e-‐FISCAL: www.efiscal.eu EC Contract Number: 283449 The costs of (1) and (2) are used to simulate the physical infrastructure and they are then annualised through depreciation rates to come up with yearly CAPEX. 3. Software costs correspond to yearly costs for licensing and purchasing operating systems, middleware, support contracts, applications, 3rd party software, compilers, etc. 4. Personnel costs relate to the salaries and all extra burdens assigned on salaries of all related categories, such as administrators and operators, middleware and application developers, trainers, dissemination persons, policy makers, managers, etc. 5. Site operating costs correspond to rentals or depreciation costs of hosting premises. 6. Electricity cost refers to the power usage for the consumption of the in-‐house network devices like servers, routers, etc. It also includes the electricity consumed for cooling and hosting. 7. The network connectivity costs correspond to the yearly cost for having connection to the internet. 8. Other costs. In this category all costs not falling in any of the previous ones should be registered. Personnel training costs, training certifications, travelling expenses – participation to conferences costs, fees paid to the university/institute for hosting the site/centre, insurance fees, even fees for cloud services could be registered. The costs of (3) to (8) refer to the operating cost of physical infrastructure. They constitute the yearly OPEX. The collection of information referring to both CAPEX and OPEX could permit, among others, the execution of a cost breakdown analysis and economies of scale assessments. Additionally, external data (e.g., from EGI, PRACE, market or other literature sources) can be gathered and used for verification and cross-‐checking. The yearly cost of e-‐Infrastructures according to the scope of the study should be calculated for years 2010 and 2011. A graphical overview of the e-‐FISCAL methodology is presented in Figure 7. In the figure, we also indicate the origin of the data to be included in the model. It should be commented that the cost categories used in e-‐ FISCAL coincide with the cost categories to be used by PRACE in its TCO analysis 33 . 33 TCO analysis for PRACE that into account the following: Investment costs taking into account the expected lifespan of supercomputers, including installation costs; related Information Technology (“IT”) equipment required for the operation (storage system, back-‐up and internal computer centre networks); buildings; technical facilities, including cooling, power supply; Maintenance of the supercomputers and related IT equipment and software licenses, including vendor support for hardware and software; Maintenance of the buildings and technical facilities; Electricity charge, including the depreciation cost of the power line and main substation if needed; The staff, including management, computer centre operation, building and technical infrastructure support; Changes and upgrades that might be required during the first five years (http://www.efiscal.eu/files/presentations/samos/PRACE-‐presentation%20ALG%20e-fiscal%2020120703%20V2.pdf). e-‐FISCAL : Financial Study for Sustainable Computing e-‐Infrastructures Deliverable D2.3 – Computing e-‐Infrastructures cost estimation and analysis – Pricing and Business models 34

Most importantly, it simplifies data collection that is a prerequisite in order for the e-‐ FISCAL project to be able to gather the necessary information in order to make the costing approximations. As the researchers of the e-‐FISCAL project are external to the sites/centre entities with no access to accounting books and detailed information, the methodology developed balances accuracy and easiness of data reporting. A graphical presentation of the proposed methodology compared to full cost accounting and TCO is given in Figure 8. e-‐FISCAL : Financial Study for Sustainable Computing e-‐Infrastructures Deliverable D2.3 – Computing e-‐Infrastructures cost estimation and analysis – Pricing and Business models 35
