Running the workloads

Steps to set up dependancies

Rerun torch just to make sure your version's the latest one

1. git clone git@github.com:Aayush-Ankit/isca_workloads.git
2. luarocks install torch
   Note: luarocks intall may have an issue with systems seating behind a proxy, so users have to change the git config file to use https:// than git://, so please follow this instructions.
   [url "https://"]
insteadOf = git://
   Add above statements to your repository gitconfig file "e.g: vim ~/.gitconfig " For more information refer to this link --> https://github.com/luarocks/luarocks/wiki/LuaRocks-through-a-proxy
3. luarocks install nn
4. luarocks install dpnn
5. luarocks install torchx

To use with CUDA

1. luarocks install cutorch
2. luarocks install cunn
3. luarocks install cunnx

Install RNN dependancy (allows using sequencers)

1. cd rnn
2. luarocks make rocks/rnn-scm-1.rockspec
   Note: the above command may break due to no proper rnn directory CMakeList cleanup. If that occurs please delete rnn and reclone the directory and run it again.
   2.a rm rnn
   2.b git clone git@github.com:Element-Research/rnn.git
   2.c Repeat steps 1 and 2 again

Yay! Setup's Done!!!

Running a benchmark on CPU/GPU

Some info. about the benchmarks

1. wlm_bigLSTM - bigLSTM network for word-level language modelling (Google 1B dataset)
2. wlm_anotherLSTM - another deep LSTM network for word-level language modelling (Google 1B dataset)
3. nmt_l5 - Google Machine Tranalation for English-French (WMT15 dataset)
4. nmt_l3 - Google Machine Tranalation for English-French (WMT15 dataset)

th <.lua> -gpu <0/1> -threads <non-zero> -batch <non-zero>

cmdline options:

1. gpu > use 0 for CPU run, 1 for GPU run (default is CPU)
2. threads > useful for CPU runs, can increase to evaluate CPU performance (default is 1)
3. batch > can be varied to find the CPU, GPU numbers (inference time, power) variation. FOr GPU, can increase batchsize until torch throws THCudaCheck: out of memory error

Metrics of Interest which are printed

1. Number of parameters in the network
2. Inference time on (CPU/GPU) NOTE: For, CPU inference time, run it twice (and use the 2nd value) to make sure the data movement cost from HDD isn't included
3. The <>pow.txt file shows gpu power consumption
