With the growth of Cloud based technologies, so have the cloud based services grown over the past few years. To meet the demands from the Cloud users, service providers have to support such a service environment that can be deployed and cloned automatically and easily. To help tackling such an issue, the Ezilla, which is considered as a private Cloud toolkit, has been developed. The new approach is...
To meet the demand from the Cloud users, service providers have to provide such a service environment that can be deployed and provisioned quickly and easily. To help tackle such an issue, the Ezilla which is considered as a private Cloud toolkit, has been developed by the Per Comp Team in the National Center for High-performance Computing. The Ezilla integrates the de facto Cloud middleware, Web-based...
Deployment of server virtualization almost becomes a universal basic concept of making full use of the data center resources. With the evolution trend for powerful multi-core servers, more memory capacity, and greater bandwidth network channel, it is necessary to think about the network I/O. To contribute this issue, Ezilla has been developed by Pervasive Computing Team at National Center for High-performance...
As Cloud services are burgeoning and attractive to HPC developers in virtue of the virtualization technology, how to establish their own dedicated virtual cluster easily become a very important problem. To contribute this issue, Easy Virtual Cluster with Cloud Storage (called VClouster) has been developed by Pervasive Computing Team in the National Center for High-performance Computing (NCHC). Just...
The network technologies and storage devices are developing quickly and the technical devices are inexpensive. Therefore, users have a large amount of storage space, Data Grid can collect distributed storage device to share to other users. In this paper, we discuss several file systems that consist of NFS, SRB, iRODS, Lustre, Gfarm and GPFS-WAN. In Data Grid, we select the specific file system to...
In this paper, we present the design of PU-DG optimizer toolbox (also known as PU-DG Optibox), which not only finds out the best strategy according to huge amount of simulation results but also proposes the min-max balancing workload method to upgrade the efficiency of execution in data grid environments. Data grid is one of key factors to build up large-scale dataset storage system and providing...
Data Grid is one of key factors to build up large-scale dataset storage system and providing high performance computing capacity, by connecting distributed resources in the Grid. One major challenge in data grids is how to provide good and timely access to huge amount of data in distributed locations, given the high latency of interconnection networks. Parallel downloading methods can improve download...
