The Cray C90 series (initally named the '''Y-MP C90''') was a Vector Processor Supercomputer launched by Cray Research in 1991. The C90 was a development of the Cray Y-MP architecture. Compared to the Y-MP, the C90 processor had a dual vector pipeline and a faster (4.1 ns or 244 MHz) clock speed, which together gave three times the performance of the Y-MP processor. The maximum number of processors in a system was also doubled from eight to 16. The C90 series used the same Model E IOS (Input/Output Subsystem) and UNICOS Operating System as the earlier Y-MP Model E. The C90 series included the C94, '''C98''' and '''C916''' models (configurations with a maximum of four, eight, and 16 processor respectively) and the '''C92A''' and '''C94A''' (air-cooled models). Maximum SRAM memory was between 1 and 8 GB, depending on model. The D92, '''D92A''', '''D94''' and '''D98''' (also known as the '''C92D''', '''C92AD''', '''C94D''' and '''C98D''' respectively) variants were equipped with slower, but higher-density DRAM memory, allowing increased maximum memory sizes of up to 16 GB, depending on model.
