Gold Features

Rations resources to projects and users

A uniquely flexible account design allows resource credits to be allocated to specific projects, users and machines.
Expiring Allocations
Resource credits may be restricted for use within a designated time period allowing sites to implement a use-it-or-lose-it policy to prevent year-end resource exhaustion and establishing a project cycle.
Nested Accounts
A hierarchical relationship may be created between accounts. This allows for the delegation of management responsibilities, the establishment of automatic rules for the distribution of downstream resource credits, and the option of making higher level credits available to lower level accounts.

Supports real-time resource charging

Dynamic Charging
Rather than post-processing resource usage records on a periodic basis to rectify project balances, accounts can be updated immediately at job completion.
Before a job runs, a hold is placed against the account for the estimated number of resource credits, followed by an appropriate withdrawal at the moment the job completes, thereby preventing projects from using more resources than were allocated to them.
Flexible Charging
The system can track and charge for composite resource usage (memory, disk, CPU, etc). Custom charge multipliers can also be applied (Quality of Service, Node Type, Time of Day, etc).

Maintains historical usage records

Gold implements a journaling mechanism that preserves the indefinite historical state of all objects and records. This powerful mechanism allows historical bank statements to be generated, provides an undo/redo capability and allows commands to be run as if it were any arbitrary time in the past.

Empowers staff and saves time

Familiar Banking Operations
Gold supports familiar operations such as deposits, withdrawals, balance feedback, transfers and refunds.
Web Interface
Gold features a powerful web-based GUI for easy remote access for users, managers and administrators. Note that the GUI is not yet available in the Alpha release.
Gold allows the establishment of default projects, machines and users. Additionally Gold can allow user, machines and projects to be automatically created the first time they are seen by the resource management system. These features allow job submitters to use the system without even knowing it.
Credit and Debit Accounts
Accounts feature an optional credit limit allowing support for both debit and credit models. This feature can also be used to enable overdraft protection for specific accounts.

Facilitates capacity planning

Project Cycles
By analyzing current and historical usage patterns and by imposing project cycles through the periodic expiration of allocations, project proposal committees can make more informed decisions on how many additional projects can be supported or what additional computing resources might be needed.

Enables grid computing

Multi-Site Exchange
A traceback mechanism will allow all parties of a transaction (resource requestor and provider) to have a first-hand record of the resource utilization and to have a say as to whether or not the job should be permitted to run, based on their independent policies and priorities. A job will only run if all parties are agreeable to the idea that the target resources can be used in the manner and amount requested. Support for traceback debits will facilitate the establishment of trust and exchange relationships between administrative domains.
Guaranteed Quotes
Users and resource brokers can determine ahead of time the cost of using resources.

Highly customizable and flexible

Dynamic Customization
Sites can create or modify record types on the fly enabling them to meet their custom accounting needs. Dynamic object creation allows sites to customize the types of accounting data they collect without modifying the code. This capability turns this system into a generalized information service. This capability is extremely powerful and can be used to manage all varieties of custom configuration data, to provide meta-scheduling resource mapping, or to function as a persistence interface for other components.
Powerful Querying
Gold supports a powerful querying and update mechanism that facilitates flexible reporting and streamlines administrative tasks.

Emphasizes scalability, security and maintainability

Gold supports multiple security mechanisms for strong authentication and encryption.
Role Based Authorization
Gold provides fine-grained (instance-level) Role Based Access Control for its operations.
Open Source
Being open source allows for site self-sufficiency, customizability and promotes community development and interoperability.
