PyQ not picking up CPUS env variable when running as a Jupyter kernel about pyq

[abalkin]

The CPUS environment variable is only used by the pyq executable and the jupyter kernel calls q directly. In order to set the CPU affinity for the kernel process, you will have to replace "/opt/kx/3.4/l64/q" with a script that calls taskset.

Hi Abalkin,

Thank you for your reply. How would this change my installation? Could you please provide an example and a bit more detail on the installation instruction? Really appreciate this.

Thanks

Please try to change "argv" in your kernel.json file to

    "argv": [
        "taskset", "-c", "0",    
        "/opt/kx/3.4/l64/q",
        "pyq-kernel.p",
        "1024",
        "65535",
        "{connection_file}"
    ],

You can change "0" above to the desired list of processors.
