My problem is that the second notebook file opens but waits for the first notebook to be evaluated. I want to execute both file1.nb and file2.nb at the same time. Here is my code. any idea?

NotebookPauseForEvaluation[nb_] := Module[{},
    While[NotebookEvaluatingQ[nb], Pause[1]]
];

NotebookEvaluatingQ[nb_] := Module[{},
    SelectionMove[nb, All, Notebook];
    Or @@ Map["Evaluating" /. # &, Developer`CellInformation[nb]]
];

UsingFrontEnd[
    nb1 = NotebookOpen["./file1.nb"];
    SetOptions[nb1, Evaluator -> "RemoteKernel1"];
    SelectionMove[nb1, All, Notebook];
    SelectionEvaluate[nb1];
    NotebookPauseForEvaluation[nb1];
    NotebookSave[nb1];
    
    nb2 = NotebookOpen["./file2.nb"];
    SetOptions[nb2, Evaluator -> "RemoteKernel2"];
    SelectionMove[nb2, All, Notebook];
    SelectionEvaluate[nb2];
    NotebookPauseForEvaluation[nb2];
    NotebookSave[nb2];
    
  ];

  • $\begingroup$ Before executing the notebooks, assign different kernels to the two notebooks, using the menu option Evaluation > Notebook's Kernel. Note, however, that your license may limit the number of kernels running simultaneously. $\endgroup$

  • $\begingroup$ Another thing you usually should do is assure that the default Contexts for the two notebooks are different, so that they do not interfere with each other. I usually use Evaluation > Notebook's Default Context > Unique to This Notebook. $\endgroup$

  • $\begingroup$ Since this code runs in a hpc cluster, i don't have access to compute nodes to do this, how can i do this programmatic? $\endgroup$

  • $\begingroup$ Good question for which I do not have an answer. If you can get to the Options Inspector you can set many useful defaults, including Unique to This Notebook. $\endgroup$
