Mathematica can be thought of as two distinct parts, a kernel and a front end. The front end is what you see on your screen (graphics, text, and display of your computations), while the kernel takes care of almost everything else, including the vast majority of computations.
Using a remote kernel to perform your computations is very convenient if your computer has limited hardware resources or is being used for other tasks. Mathematica can automate the running of remote kernels.
- In the Machine Name field (Remote Host on Mac OS X), enter either the name of the remote machine on your network or its IP address.
- In the Kernel Program field, give the command that would be used to run Mathematica through a terminal window on the remote machine. (In this example, the full path is not necessary because the remote kernel is on a Linux machine where a symbolic link to the kernel program "math" is in the search path.)
You can now direct the front end to use the remote kernel. Select a notebook, and then select Evaluation ► Notebook's Kernel ► LinuxKernel. In this example, LinuxKernel is the name given to the remote kernel during setup:
