Standard computer architectures suffer from von Neumann bottlenecks for all processing is done exclusively on the processor.
The computer's memory is not involved in processing, as it is only used to store programs and data. When a computing system or application has large amounts of data, moving data between memory and the processor can slow down processing.
Adding processing directly into memory can help alleviate this problem. Processing In Memory (PIM) or Processing Near Memory (PNM) is capable of manipulating data in computer memory.
By moving part of the computation to a memory device, PIM/PNM solves a fundamental problem in modern computing system design: the mismatch between von Neumann architectures and the huge memory bandwidth demanding of applications.
Many industrial prototypes and products are under development or are already available on the market, and these devices show promise for cost-effective and energy-efficient acceleration of HPC, AI, and Big-Data analytics workloads.
This panel will discuss the reasons for the renewed interest in PIM/PNM and its technological readiness and challenges in terms of Applications, System and SW.
