I am trying to start qJupyter on one of our servers.
All well, but I need to modify the q command it uses because we only have a licence for 2 cores on our dev server and I need to append taskset -c 1,2 before the q command.
Does anyone know how to achieve that ?

Edit the file https://github.com/KxSystems/jupyterq/blob/master/kernelspec/kernel.json

{  "argv": [   "taskset",   "-c",   "0,1",   "q",   "jupyterq_kernel.q",   "-cds",   "{connection_file}"  ],  "display_name": "Q (kdb+)",  "language": "q",  "env": {"JUPYTERQ_SERVERARGS":"","MPLBACKEND":"Agg"} }

If you have already installed you can ensure Jupyter picks up the changes by reinstalling the kernel:

python -m jupyter kernelspec install --user --name=qpk /path/to/kernelspec

And you can validate in a notebook with system"taskset -pc ",string .z.i:

 

?
