The European Commission has supported substantial investment in building and integrating electronic research infrastructures comprising of High Performance Computing resources and data warehouses with large storage capacities and advanced features. The Bulgarian supercomputer system Avitohol has been deployed and reached number 332 in the Top500 list in July 2015 with a theoretical performance of 416 TFlop/s. In order to maximize the use of such expensive equipment it is necessary to deploy an integrated set of services that provide flexible and transparent access. In this paper we describe the main services that provide a virtual research environment that fulfils these needs. We discuss the main features of such services and their benefits for industrial applications, especially when SMEs collaborate with HPC centres.
