- Pong 1.5 is installed at /apps/eb/pong/1.5-foss-2020b-Python-3.8.6
To use pong 1.5, please load the module:
ml pong/1.5-foss-2020b-Python-3.8.6
To use pong on Sapelo2 with an interactive job
The port number for the pong server should be some random value between 8000 and 10000. Assign this value to the variable 'NOTEBOOKPORT' in the submission script below replacing 8888. Please do not use 8888. If more than one person uses that same value you cannot establish the ssh tunnel.
Sample steps to use pong 1.5, once you connect to Sapelo2, using pong's sample data:
interact wget https://brown.edu/Research/Ramachandran_Lab/files/pong/pong-example-data_1kG-p3.zip unzip pong-example-data_1kG-p3.zip cd pong-example-data_1kG-p3 NOTEBOOKPORT=8888 IPUSED=$(hostname -i) echo "NOTEBOOKPORT is " $NOTEBOOKPORT echo "IPUSED is " $IPUSED ml pong/1.5-foss-2020b-Python-3.8.6 pong -m pong_filemap -n pop_order_expandednames.txt -i ind2pop.txt -p 8888
After running the steps above, establish a another ssh tunnel from your desktop or laptop to sapelo2 login node at port NOTEBOOKPORT.
For Mac/Linux Users
If you are using a Linux or Apple machine for your desktop or laptop you can use the following command to establish the ssh tunnel
Make sure you replace NOTEBOOKPORT and IPUSED below with the port number and the IP address you are using (see the output of the echo commands above)
ssh -N -L NOTEBOOKPORT:IPUSED:NOTEBOOKPORT username@sapelo2.gacrc.uga.edu
Unless you have ssh key configured, you will be prompted for your MyID password and for Archpass Duo authentication. Once authentication is established, this session prompt will hang and you are ready to go to the next step.
For Windows Users
If you are using a Windows machine for your desktop or laptop download the plink program to use in place of the ssh client. The command for windows would be as follows: Assuming the plink.exe is in the current directory where you have a command window open.
Make sure you replace NOTEBOOKPORT and IPUSED below with the port number and the IP address you are using (see the output of the echo commands above)
plink -ssh -N -L NOTEBOOKPORT:IPUSED:NOTEBOOKPORT username@sapelo2.gacrc.uga.edu
Once you establish the ssh tunnel by running the command above you can access pong by going to http://localhost:NOTEBOOKPORT using the browser on your desktop or laptop (make sure you replace NOTEBOOKPORT with the port number you used in the interact session). The interact terminal might show something like this:
