How to modify the execution command in qJupyter?
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/kernelspecAnd you can validate in a notebook with
system"taskset -pc ",string .z.i:?
