The architecture of Context Analysis of the Camera Data Streams for Alert Defining Applications platform (Polish abbreviation: KASKADA, i.e. waterfall), a part of MAYDAY EURO 2012 project, is provided. A new multilayer processing model for multimedia streams is proposed. The model layers: services, computational tasks and processes are described. The(More)
KASKADA is a platform designed for supporting and managing multimedia processing in a supercomputer environment. Its core components and mechanisms are presented and discussed. In particular: multimedia stream organization and pre-processing, as well as event detection and handling for critical situations, are described. For each component of the platform(More)
The paper presents modeling and simulation of energy consumption of two types of parallel applications: geometric Single Program Multiple Data (SPMD) and divide-and-conquer (DAC). Simulation is performed in a new MERPSYS (Modeling Efficiency, Reliability and Power consumption of multilevel parallel HPC SYStems using CPUs and GPUs) environment. Model of an(More)
1 Summary. The paper presents a method of hardware load prediction using workload models based on application categories and high-level characteristics. Application of the method to the problem of optimization of virtual machine scheduling in a heterogeneous Infrastructure as a Service (IaaS) computing cloud is described. Streszczenie.
