FBSAM data transmission package for IBM 360/370 computers. [For rapid movement of large blocks of data directly between user storage arrays and magnetic disk data sets, in FORTRAN IV and assembly language]
The FBSAM subroutine package provides rapid movement of large blocks of data directly between user storage arrays and magnetic disk data sets. No buffer space is required. Large reductions in data transmission time and number of I/0 requests can be obtained. Moves can be concurrent with each other and with computation. A form of random access is available. A demonstration program provides a thorough test of all features. The package is intended for use by FORTRAN programers with little or no assembler language experience. It should be operable on most IBM 360/370 machines. A sample application to an I/0-bound code is discussed. The use of three concurrent functions entirely eliminated the real time associated with data transmission tasks by allowing them to proceed concurrently with other tasks. 2 figures, 1 table (auth)
