Computing Grids
According to Greg Pfister, what is the ideal goal for a cluster to appear as a single, integrated, powerful resource to the user?
High Availability (HA)
Single-System Image (SSI)
Distributed Shared Memory (DSM)
Massive Parallel Processing (MPP)
Which cloud service model provides a virtualized environment for developers to build and manage applications using APIs, middleware, and development tools?
Infrastructure as a Service (IaaS)
Software as a Service (SaaS)
Platform as a Service (PaaS)
Data as a Service (DaaS)
What is a primary characteristic of unstructured P2P overlay networks?
They follow a specific connectivity topology.
They often use flooding to send queries, resulting in heavy network traffic.
They have strict rules for inserting and removing nodes based on peer IDs.
They offer deterministic and predictable search results.
Which type of cloud deployment is operated solely for an organization to ensure the highest level of security control?
Public Cloud
Private Cloud
Managed Cloud
Hybrid Cloud
In the context of the "Data-Intensive Computing Era," what is the recommended future trend for handling petascale data sets?
Moving data to local workstations for processing.
Centralizing all data into a single physical disk array.
Sending computations to the data.
Utilizing only serial programming environments.
Which system model is characterized by autonomous nodes that act as both client and server with no master-slave relationship?
Computer Clusters
Internet Clouds
Peer-to-Peer (P2P) Systems
Computational Grids
Based on 2009 statistics, how many of the Top 500 supercomputers were built using cluster architecture?
150
325
417
480
Which specific challenge is cited by the sources as a reason why Grids have been underutilized?
High cost of participation for users.
Lack of reliable middleware.
Inability to support scientific applications.
Too much centralization
Which cloud service model involves the delivery of browser-initiated application software (such as CRM or ERP) to customers with no upfront investment?
IaaS
PaaS
SaaS
SSI
