Adopting a virtual machine manager system for better throughput performance when it is used in cloud environments [article]

Dimitrios A. Bliablias, National Technological University Of Athens, National Technological University Of Athens, Νεκτάριος Κοζύρης
A software tool is commonly used that manages the physical nodes of the cluster, and the virtual resources as well.  ...  This thesis aims to improve the performance of such a tool, and specifically Ganeti's, by providing support for alternative engines to serve its storage requirements.  ...  Firstly, as Ganeti is a software tool for managing clusters of physical nodes, it is not a facile task to obtain, setup, and maintain physical machines for the cluster requirements.  ...

Its most crucial function is to collect machine learning algorithms employed for data mining tasks. The algorithms can either be applied directly to a dataset or called from your Java code.  ...  Weka is also suitable for creating new machine learning schemes and it is an open source software issued under the GNU General Public License.  ...  s ( name = " Average S a l e s ( e u r o s ) " , data = a03$ S a l e s / 4 ) %>% hc add s e r i e s ( name = " Average Quantity ( Kgrs ) " , data = a03$ Quantity / 4 ) %>% hc add s e r i e s ( name = "  ...
