In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

OS 2200 supports all commonly used, and many not so commonly used, distributed processing protocols, APIs, and development technology. The X/Open Distributed Transaction Processing model and standards are the basis for much of the OS 2200 capability. Full support for the X/Open XA APIs including two-phase commit are built into transaction middleware, the database managers, and even clustering. The J2EE model is also fully supported. It uses the XA capabilities of the system but provides the J2EE APIs and protocols. IBM WebSphere MQ (AKA MQSeries), MSMQ, and others are all fully integrated into the system taking advantage of the XA and integrated recovery facilities.
The International Parallel and Distributed Processing Symposium (or IPDPS) is an annual conference for engineers and scientists to present recent findings in the fields of parallel processing and distributed computing. In addition to technical sessions of submitted paper presentations, the meeting offers workshops, tutorials, and commercial presentations & exhibits. IPDPS is sponsored by the IEEE Computer Society's Technical Committee on Parallel Processing. IPDPS is a week-long symposium that typically includes three days of a main track, two days of about 20 workshops bookending the main track, one or more tutorials, a panel, several keynote talks, and a banquet. The main track consists of high-quality, peer-reviewed papers representing original unpublished research in all areas of parallel and distributed processing, including the development of experimental or commercial systems. IPDPS topics of interest include, but are not limited to: Parallel and distributed algorithms, focusing on issues such as: stability, scalability, and fault tolerance of distributed systems, communication and synchronization protocols, network algorithms, and scheduling and load balancing. Applications of parallel and distributed computing, including web applications, peer-to-peer computing, grid computing, scientific applications, and mobile computing. Parallel and distributed architectures, including shared memory, distributed memory (including petascale system designs, and architectures with instruction-level and thread-level parallelism), special-purpose models (including signal and image processors, network processors, other special purpose processors), nontraditional processor technologies, network and interconnect architecture, parallel I/O and storage systems, system design issues for low power, design for high reliability, and performance modeling and evaluation. Parallel and distributed software, including parallel programming languages and compilers, runtime systems, operating systems, resource management, middleware, libraries, data mining, and programming environments and tools.
Distributed Processing Technology Corporation (DPT) was an American computer hardware company active from 1977 to 1999. Founded in Maitland, Florida, DPT was an early pioneer in computer storage technology, popularizing the use of disk caching in the 1980s and 1990s.
Distributed data processing (DDP) was the term that IBM used for the IBM 3790 (1975) and its successor, the IBM 8100 (1979). Datamation described the 3790 in March 1979 as "less than successful." Distributed data processing was used by IBM to refer to two environments: IMS DB/DC CICS/DL/I Each pair included a Telecommunications Monitor and a Database system. The layering involved a message, containing information to form a transaction, which was then processed by an application program. Development tools such as program validation services were released by IBM to facilitate expansion. Use of "a number of small computers linked to a central computer" permitted local and central processing, each optimized at what it could best do. Terminals, including those described as intelligent, typically were attached locally, to a "satellite processor." Central systems, sometimes multi-processors, grew to handle the load. Some of this extra capacity, of necessity, is used to enhance data security. Years before open systems made its presence felt, the goal of some hardware suppliers was "to replace the big, central mainframe computer with an array of smaller computers that are tied together."
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
