IBM Telum

Telum is a microprocessor made by IBM for the IBM z16 series mainframe computers. The processor was announced at the Hot Chips 2021 conference on 23 August 2021. Telum is IBM's first processor that contains on-chip acceleration for artificial intelligence inferencing while a transaction is taking place.

Description
The chip contains 8 processor cores with a deep superscalar out-of-order pipeline, running with more than 5 GHz clock frequency which is optimized for the demands of heterogenous enterprise-class workloads (e.g: finance, security sensitive applications, applications requiring extreme reliability). The cache and chip-interconnection infrastructure provides 32 MB cache per core and can scale to 32 Telum chips. Unlike other processors, the IBM Telum does not thermal throttle by reducing clock speed; instead it inserts sleep state instructions. The Neural Network Processing Assists (NNPA) instruction performs a variety of tensor instructions useful for neural networks. Telum II adds new functions to NNPA. ==See also==
