IBM ISeries Benchmarks
The Commercial Processing Workload (CPW) is a simplified variant of the industry-wide TPC-C benchmarking standard originally developed by IBM to compare the performance of their various AS/400 (now IBM i IBM i (the ''i'' standing for ''integrated'') is an operating system developed by IBM for IBM Power Systems. It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in ...) server offerings. The related, but less commonly used Computational Intensive Workload (CIW) measures performance in a situation where there is a high ratio of computation to input/output communication. The reverse situation is simulated by the CPW. References External linksTPC slaps Oracle on benchmark claims The Register Benchmarks (computing) IBM software {{compu-hardware-stub ...

TPC-C
TPC-C, short for Transaction Processing Performance Council Benchmark C, is a benchmark used to compare the performance of online transaction processing (OLTP) systems. This industry standard was published in August 1992, and eventually replaced the earlier TPC-A, which was declared obsolete in 1995. It has undergone a number of changes to keep it relevant as computer performance grew by several orders of magnitude, with the current version , 5.11, released in 2010. In 2006, a newer OLTP benchmark was added to the suite, TPC-E, but TPC-C remains in widespread use. The TPC-C system models a multi-warehouse wholesale operation, known simply as "the Company". In a minimal test, the company has ten warehouses, each with ten user terminals. Each warehouse serves ten defined sales districts, each with 3,000 customers who are ordering against a product catalog of 100,000 items. The most frequent transactions are customer orders, with an average of ten items on each order, and customer pay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AS/400
The IBM AS/400 (Application System/400) is a family of midrange computers from IBM announced in June 1988 and released in August 1988. It was the successor to the System/36 and System/38 platforms, and ran the OS/400 operating system. Lower-cost but more powerful than its predecessors, the AS/400 was extremely successful at launch, with an estimated 111,000 installed by the end of 1990 and annual revenue reaching $14 billion that year, increasing to 250,000 systems by 1994, and about 500,000 shipped by 1997. A key concept in the AS/400 platform is Technology Independent Machine Interface (TIMI), a platform-independent instruction set architecture (ISA) that is compiled along with the native machine language instructions. The platform has used this capability to change the underlying processor architecture without breaking application compatibility. Early systems were based on a 48-bit CISC instruction set architecture known as the ''Internal Microprogrammed Interface'' (IMPI), o ...

IBM I
IBM i (the ''i'' standing for ''integrated'') is an operating system developed by IBM for IBM Power Systems. It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in 2004, before being renamed a second time to IBM i in 2008. It is an evolution of the System/38 CPF operating system, with compatibility layers for System/36 SSP and AIX applications. It inherits a number of distinctive features from the System/38 platform, including the Machine Interface, the implementation of object-based addressing on top of a single-level store, and the tight integration of a relational database into the operating system. History Origin OS/400 was developed alongside the AS/400 hardware platform beginning in December 1985. Development began in the aftermath of the failure of the Fort Knox project, which left IBM without a competitive midrange system. During the Fort Knox project, a skunkworks project was started ...
