When running our non-Mathematica scheduler, if we send to execute
"Mathematica.exe first.nb" the application starts running first.nb
If we send the second notebook to execute ("Mathematica.exe second.nb")
there is no new instance of Mathematica.
Instead the second.nb opens in the already existing Mathematica process
for the first notebook.
Manually we can click on the Mathematica shortcut and we can get two
instances of Mathematica running simultaneously.
We would like to do the same using a command line. Open two different
notebooks and have them run in separate Mathematica instances, though
running simultaneously in real time.
Could someone please advice us on how we can accomplish this.
The easiest way to do this is to change evaluator in the second
notebook. To do this, use menu "Kernel\Kernel Configuration Options.."
then click New, change the name and hit OK. Next choose the newly
created kernel as the notebook's evaluator, by opening the notebook
in Mathematica, and using "Kernel\Notebook's kernel".
Then running Mathematica.exe second.nb would automatically launch
a new kernel for the second notebook, while the first notebook
would be running on the default kernel.
This recipe is subject to license limitations. Your license should
allow you to run two kernels at the same time.
