Abstract
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 easy operation, NCHC VClouster helps building a Computing Cloud for HPC numerical simulation. It satisfies various customized demands and has high scalability for virtual machines (VM) so the performance of using Cloud service can be improved. NCHC VClouster system is a friendly design for Cloud users to send their requests, through the user specification it would create a customized and dedicated virtual cluster on demand for different users automatically. The system leverages Cloud toolkit combined with Cloud storage service, then Cloud users do not worry about the transmission of a huge amount of application data. NCHC VClouster also introduces International Certificate Authority (CA) services so that authorized users can easily utilize their virtual machines and integrate more computing resources in same CA organization.
