Notice

NEEDLE and runframework are borrowed from https://www.github.com/sfu-arch and modified for this projcet

Dependencies

gcc 4.8+ cmake minimum VERSION 2.8 boost library - 1.61 used pin3.0 Macsim - uses 64 bit shared library generated from pin gems ruby

Directory Structure

You will see files with following extensions: macsim.r.d.b.s r= ruby d = dafaxc b = bloom filter s = standalone

It just means that it includes those modules

Toplevel Directory contains: apps tools

apps- bloom.s dafaxc.r.b.s macsim.r.d.b.s

bloom.s = standalone module for various types of bloom filters borrowed from gems

dafaxc = dataflow accelerator, which reads dot graphs (dependency : boost) r. = ruby b. = bloom filter

tools- c++/may-profile

longest_path may-profile mead pin-tools

longest_path = is a python script that reads in the hottest path in the form of dotgraph and finds the longest_chain mead = is a python script which reads a dot graph and finds original edges, added edges by compiler and other info

PITFALLS

RUBY : hardcoded CC= g++ ; need to manually change at $HOME/apps/macsim.r.d.b.s/macsim-mem-axc-64/gems-lib-ooo/common/Makefile.common

To get the stack addreses for pin tool Commented from pasha/tools/mwe/main.cpp // pm.add(new mwe::MicroWorkloadExtract(SeqFilePath, ExtractedModules));

Installation

## THIS README IS INCOMPLETE, FOLLOW THE README IN apps/dafaxc.r.b.s to build that
## TO BUILD GEMS - FOLLOW THE README IN apps/macsim.r.d.b.s/macsim-mem-axc-64

mkdir build_repo
cd build_repo
mkdir build-mem-axc-64
cd build-mem-axc-64
mkdir bloom && cd bloom
cmake <path/to/bloom.s>
make -j 8
cd ../
mkdir dafaxc
# in the cmake file of dafaxc set the path to the generated libbloom.a in the previous folder
cmake -DBOOST_ROOT= <path/to/boost>  <path/to/dafaxc>
make -j 8

```bash
