Guide/cheatsheet for working on the optimization lab with DAS5.

You should already have a ssh user assigned to you and a password.

Replace all usage of kics2001 in this guide with your own username. (And you may wish to replace fs1.das5.liacs.nl as well)

Setup

Make key and register it with DAS5:

ssh-keygen
ssh-copy-id [email protected]

Copy all files to das5

cd optimizationlab
scp * [email protected]:

Log in to das5

ssh [email protected]

Test on das5

1. Modify driver.py, set ON_DAS5=True

2. Copy updated driver.py to DAS5:

   scp driver.py [email protected]:
   

3. Log in to das5 and run (once):

   chmod +x driver.py
   

4. You can build and test the files when logged in to DAS5:

   make
   module load prun
   ./driver.py
   

5. Or you can build files locally and copy the binaries to DAS5:

   make
   scp k_nearest_seq [email protected]:
   ssh [email protected] "module load prun; ./driver.py"
   

Here is a script that will build the binaries locally, upload all of them to DAS5 and test them there

#!/bin/bash

make
scp k_nearest_seq [email protected]:
scp k_nearest_simd [email protected]:
scp k_nearest_thread [email protected]:
ssh [email protected] "module load prun; ./driver.py"

Save to test.sh for example, and run with ./test.sh (Do chmod +x test.sh first once)

Tip: make a ssh configuration for DAS5

~/.ssh/config

Host das
    User kics2001
    HostName fs1.das5.liacs.nl

Then you can replace the use of [email protected] on ssh calls everywhere with just das.

For eaxmple ssh das or scp driver.py das:

Alternative: Use VSCode Remote to do everything on the DAS5
