The Cray X-MP/Model 24. A case study in pipelined architecture and vector processing (Q1187670)

Excellent booklet! The booklet gives a detailed description of the hardware (assembler) instructions, their timings, their mutual interference and their relation to programming style. A description of interprocessor communication and multitasking is included. The appendix contains an instruction execution summary of the X-MP. The presentation of the material is an excellent combination of explanations and examples. Unfortunately the booklet describes the ``old'' X-MP (without gather/scatter/compressed index instructions) that has now developed to the X-MP with improved memory access, so that detailed information is already obsolete, but the basic information is not.
