HBM2-PIMSimulator-lab

1. Overview

This repository is used for HBM2-PIM lectures at the KAIST AI-PIM Center. The lab lectures consist of slides explaining the lab and simulator code from this repository.

This simulator repository is based on the the HBM2-PIM simulator repository. The existing HBM2-PIM simulator is managed and maintained at https://github.com/SAITPublic/PIMSimulator. Please refer to this link to use it.

2. Setup

2.1 Prerequisites

• Scons tool for compiling PIMSimulator:

sudo apt install scons

• gtest for running test cases:

sudo apt install libgtest-dev

2.2 Installing

• To Install PIMSimulator:

# compile
scons

2.3 Launch a Test Run

• Show a list of test cases

./sim --gtest_list_tests

# Example
PIMKernelFixture.
  gemv_tree
  gemv
  mul
  add
  relu
MemBandwidthFixture.
  hbm_read_bandwidth
  hbm_write_bandwidth
PIMBenchFixture.
  gemv
  mul
  add
  relu

• Test Running

# Running: functionality test (GEMV)
./sim --gtest_filter=PIMKernelFixture.gemv

# Running: functionality test (MUL)
./sim --gtest_filter=PIMKernelFixture.mul

# Running: performance test (GEMV)
./sim --gtest_filter=PIMBenchFixture.gemv

# Running: performance test (ADD)
./sim --gtest_filter=PIMBenchFixture.add
