- Attached_Support_Processor abstract "Attached Support Processor (ASP) was an implementation of loosely coupled multiprocessing for IBM's OS/360 operating system.ASP evolved from the design of the 7094/7044 direct coupled system, using data channel to data channel communication. By attaching an IBM 7044 as a peripheral processor throughput was more than doubled.ASP was introduced in March 1967, and initially allowed connection of two System/360 computers via a channel-to-channel adapter (CTCA).As initially defined an ASP system consisted of a large System/360 computer, a Model 50, 65, or 75 running OS/360, called the main processor, and a smaller System/360, Model 40 or larger, called the support processor, running the ASP supervisor as a single task under OS/360 PCP (Primary Control Program). The support processor performed functions such as printing, card reading and punching, freeing the main processor to run the application workload. It queued jobs, roughly 30 in the basic configuration, and released them to the main processor in priority order, and also did pre-execution setup of removable input/output devices such as disks and tapes on the main processor.The main processor was configured identically to a "stand-alone processor operating under OS/360, except that thechannel-to-channel adapter replaces the normal system inputand output devices." The support processor was a minimum of a Model 40 G (G indicates memory size of 128KB) with two selector channels, a 1052 console typewriter, a 2540 card read/punch, a 1403 printer, and three 2311 disk drives. It was recommended that the support processor have access to one 2400-series tape drive for support. The OS version on the main processor was modified to be able to overlay itself with the 7090/94 emulator program when an emulator job was to be run, and the emulator program would similarly overlay itself with OS/360 when done, to process emulated 709x jobs intermixed with standard 360 jobs.With the introduction of System/370 ASP was renamed Job Entry Subsystem 3 (JES3) and is still in use as of 2014.".
