Proceedings of the USENIX ... Annual Technical Conference. USENIX Technical Conference
|September 28, 2011
Summary
The Free Factory platform enables data-intensive web services on commodity hardware using virtual machines called Freegols. This system optimizes distributed batch processing, cache, and storage for high-throughput data operations.
Area of Science:
- Computer Science
- Distributed Systems
- Cloud Computing
Background:
- Deploying data-intensive web services often requires significant infrastructure investment.
- Existing solutions may lack flexibility or efficient resource utilization for distributed tasks.
Purpose of the Study:
- To introduce the Free Factory, a novel platform for deploying data-intensive web services.
- To leverage commodity hardware and free software for scalable and cost-effective data processing.
Main Methods:
- Utilizing independently administered virtual machines (Freegols) for application deployment.
- Implementing distributed batch processing (MapReduce variation), cache, and storage services within clusters.
- Exploiting idle RAM and disk space for caching and reserving disks for high-bandwidth storage.
Main Results:
- Each 48-node cluster achieves 4-8 gigabytes per second of disk I/O.
- Current applications demonstrate 1 gigabyte per second I/O with 123 disks across two clusters.
- Virtualization enables all cluster CPUs to participate in batch jobs.
Conclusions:
- The Free Factory offers a flexible and efficient solution for data-intensive web services.
- The platform demonstrates high I/O performance and scalability for large datasets.
- Future work includes processing multi-hundred terabyte datasets with multiple clusters.

01:26Steel Manufacturing
Steel manufacturing is a multi-stage process that begins by smelting iron ore into cast iron in a blast furnace. This initial stage involves layering iron ore with coke, a type of fuel, and crushed limestone within the furnace. The coke is ignited with a high volume of air, leading to the creation of carbon monoxide, which acts to reduce the iron ore to pure iron.
During this smelting process, limestone plays a crucial role by forming slag. Slag captures impurities within the molten iron, such...

01:20Integrated Healthcare System
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...
01:19Distributed Loads
Distributed loads are a common type of load that engineers and scientists encounter in various practical situations. Distributed loads often refer to a type of load spread over a surface or a structure and can be modeled as continuous force per unit area.
For example, consider a bookshelf filled with books stacked vertically adjacent to each other. The weight of the books is evenly distributed over the length of the shelf. As a result, the pressure at different locations on the surface of the...

01:25Distribution Reliability and Automation
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...
01:34Production of Formed Elements
Hemangioblasts are multipotent stem cells originating from the mesoderm. They give rise to hematopoietic stem cells (HSCs), which undergo hematopoiesis to produce all the formed elements of blood. This process is regulated by a complex network of hematopoietic growth factors, including transcription factors, growth factors, and cytokines. These factors stimulate the HSCs to divide and differentiate, though some HSCs remain undifferentiated to maintain a self-renewing pool.
