Query: Proximu$: Efficiently Scaling DNN Inference in Multi-core CPUs through
  Near-Cache Compute   Deep Neural Network (DNN) inference is emerging as the fundamental bedrock
for a multitude of utilities and services. CPUs continue to scale up their raw
compute capabilities for DNN inference along with mature high performance
libraries to extract optimal performance. While general purpose CPUs offer
unique attractive advantages for DNN inference at both datacenter and edge,
they have primarily evolved to optimize single thread performance. For highly
parallel, throughput-oriented DNN inference, this results in inefficiencies in
both power and performance, impacting both raw performance scaling and overall
performance/watt.
  We present Proximu$\$$, where we systematically tackle the root
inefficiencies in power and performance scaling for CPU DNN inference.
Performance scales efficiently by distributing light-weight tensor compute near
all caches in a multi-level cache hierarchy. This maximizes the cumulative
utilization of the existing bandwidth resources in the system and minimizes
movement of data. Power is drastically reduced through simple ISA extensions
that encode the structured, loop-y workload behavior. This enables a bulk
offload of pre-decoded work, with loop unrolling in the light-weight near-cache
units, effectively bypassing the power-hungry stages of the wide Out-of-Order
(OOO) CPU pipeline.
  Across a number of DNN models, Proximu$\$$ achieves a 2.3x increase in
convolution performance/watt with a 2x to 3.94x scaling in raw performance.
Similarly, Proximu$\$$ achieves a 1.8x increase in inner-product
performance/watt with 2.8x scaling in performance. With no changes to the
programming model, no increase in cache capacity or bandwidth and minimal
additional hardware, Proximu$\$$ enables unprecedented CPU efficiency gains
while achieving similar performance to state-of-the-art Domain Specific
Accelerators (DSA) for DNN inference in this AI era.
