Processor Complex Configuration

The IBM 3090 is a field-upgradeable family which consists of seven models: three uniproccssors, one dyadic, one triadic, one four-way and one six-way multiprocessor. They provide up to ten-fold growth from the smallest Model l20E to the largest Model 600E.

In addition, from one to six optional Vector Facilities (one per central processor) may be configured to provide enhanced performance and modular growth for vectorisable applications.

An IBM 3090 can be installed in approximately 11 to 17 hours. Field upgrades can be made to the next higher model in nine to 24 hours depending on the model.

All IBM 3090 Processor Complexes include:

An IBM 3090 Model 120E, 150E or 180E Complex, in addition to the common support units listed above, comprises:

An IBM 3090 Model 200E or 300E Complex, in addition to the common support units listed above, comprises:

An IBM 3090 Model 400E or 600E Complex comprises:

Performance

Performance gains in the enhanced IBM 3090 family are achieved by means of cycle time reductions, technology improvements and design extensions.

The commercial comparisons for all models are Instruction Execution Rate Ratios (IERRs), while the comparisons for the compute intensive applications are Internal Throughput Rate Ratio (ITRRs). An ITRR is the measurement of the central processor time of a job on one system relative to the time on another system.

Additional details on 3090 scalar, vector and parallel performance for engineers, scientists and analysts may be found in the companion publication CS11-0136.
