+Nowadays more and more general purpose workstations installed in a student
+laboratory have built in multi-core CPU and graphics card providing significant
+computing power. In most cases the utilization of these resources is low, and
+limited to lecture hours. The concept of utility computing plays an important
+role in nowadays technological development. As part of utility computing, cloud
+computing offers greater flexibility and responsiveness to ICT users at lower
+cost.
+
+In  this paper, we introduce a cloud management system which enables the
+simultaneous use of both dedicated resources and opportunistic environment. All
+the free workstations (powered or not) are automatically added to a resource
+pool, and can be used like ordinary cloud resources. Researchers can launch
+various virtualized software appliances. Our solution leverages the advantages
+of HTCondor and OpenNebula systems.
+
+Modern graphics processing units (GPUs) with many-core architectures have
+emerged as general-purpose parallel computing platforms that can dramatically
+accelerate  scientific applications used for various simulations. Our business
+model harnesses computing power of GPUs as well, using the needed amount of
+unused machines. This makes the infrastructure flexible and power efficient.
+
+Our pilot infrastructure consist of a high performance cluster and 28
+workstations with dual-core CPUs and dedicated graphics cards. Altogether we
+can use 10,752 CUDA cores through the network.
