gearshifft Results and Analysis Tool

gearshifft Results

The FFT benchmark suite gearshifft is used to benchmark different FFT libraries on different platforms. This repository provides the benchmark results of different combinations as shown in the table below.

arch	fftw	cufft	clfft
haswell	3.3.6pl1	-	2.12.2
P100	-	9.x	2.12.2
V100	-	9.x	2.12.2
GV100	-	9.x	2.12.2
GTX1080	-	8.0.61	2.12.2
K80	-	8.0.61	2.12.2
K20Xm	-	8.0.61	2.12.2

cufft 9.x refers to cufft/CUDA 9.0.176, 9.1.85, 9.2.88.

R-Shiny Script for R driven gearshifft Data Analysis

The results obtained with gearshifft can be visualized with our r-shiny app. rshiny/app.r contains R shiny's ui and server functions. rshiny/helper.r contains R data processing of gearshifft result files.

• inspect 1 result file obtained with gearshifft
• inspect 2 result files and compare cross platform or across libraries
• upload your own result file or use results in results/ provided by gearshifft
• contains plotter, table view and meta information
• various filter settings enable deep analysis of the measurements

Online R-Shiny App

Local R-Shiny App

Several R libraries are required to run our r-shiny app locally.

ggplot2 dplyr plyr readr scales DT shiny shinythemes

After the installation you can run:

R -e "shiny::runApp('./app.r')"

Afterwards a server is started and you can access the web application via localhost and a given port number. Things like the port number and errors are shown in the output where the server has been launched.

Note: If you change the helper.r, a simple reload of the web application does not help. rshiny checks only app.r and recaches when app.r has been changed.

R-Shiny Server (Linux, systemd, nginx)

You also can run your own shiny-server application. If you run Arch Linux, take this AUR package. By the way, With shiny-server it is also possible to host interactive Rmarkdown documents.

Check [etc/] for the nginx with https (letsencrypt) and shiny-server configuration files. The following guide only covers the http path.

Some parts of this guide come from the admin guide and this howto. For SSL, check this howto.

Our environment will have one dedicated user called shiny for the rshiny apps.

• the gearshifft folder looks like:

-rw-rw-r-- 1 shiny shiny 18735 Jul 18 21:09 app.r
-rw-rw-r-- 1 shiny shiny 19561 Jul 18 21:09 helper.r
drwxrwxr-x 6 shiny shiny  4096 Jun  2 18:27 results
drwxrwxr-x 3 shiny shiny  4096 May 23 18:38 www

• install R and the packages (global)

for i in ggplot2 dplyr plyr readr DT shiny; do
 sudo su - -c "R -q -e \"install.packages('$i', repos='http://cran.rstudio.com/')\""
done

(After system update packages may need to be recompiled/reinstalled.)

• install shiny-server

• configure /etc/shiny-server/shiny-server.conf (see also the admin guide ):

server {
  listen 1337;
  run_as shiny;
  members_of shiny-apps;

  location / {
    #sanitize_errors false;
    log_dir /home/shiny/.logs/;

    app_dir /home/shiny/gearshifft/;

    directory_index off;
  }
}

• install nginx and configure /etc/nginx/servers-enabled/default

server {
        listen 80 default_server;
        location /gearshifft/ {
                proxy_pass http://127.0.0.1:1337/;
        }
}

• start the service

systemctl start shiny-server

• run nginx

systemctl start nginx

• test your website http://.../gearshifft
