NeuPIMs Simulator

This is NeuPIMs cycle-accurate simulator. We integrate open-source NPU simulator and our in-house PIM simulator based on DRAMsim3 to implement NeuPIMs simulator.

Getting Started

method 1 (Docker Image)

$ git clone https://github.com/casys-kaist/NeuPIMs.git
$ cd NeuPIMs
$ docker build . -t neupims
$ docker run -it -v .:/workspace/neupims-sim neupims
(docker) cd neupims-sim
(docker) git submodule update --recursive --init
(docker) ./build.sh

build docker image and installation

$ docker run -it -v .:/workspace/neupims-sim neupims
(docker) cd neupims-sim
(docker) ./brun.sh

run docker image

method 2 (Mannual)

Installation

$ git clone https://github.com/casys-kaist/NeuPIMs.git
$ cd NeuPIMs
$ git submodule update --recursive --init

Build

$ mkdir build && cd build
$ conan install .. --build missing
$ cmake ..
$ make -j

Run Simulator

$ cd ..
$ ./brun.sh

Baselines

1. NPU-only: Codes on npu-only branch, all operations in LLM batched inference are executed on NPU.
2. NPU+PIM: Codes on npu+pim branch, attention GEMV operations on PIM. PIM is single row buffered PIM on this baseline.
3. NeuPIMs: Codes on main branch, we use dual row buffer PIM and sub-batch interleaving technique. (Sub-batch interleaving is enabled only when batch size>=256)
