The problem is that whenever I’m interrupting the kernel manually in Jupyter the kernel doesn’t really stop and keeps on runnig! Is there a way to get around this issue ?

If the Julia code isn’t yielding at all to the event loop, e.g. if it executing an external BLAS routine, I don’t think interrupt will work, and you’ll have to restart the kernel?

Is there a way for us to know that external routines are being run ?
