For instructions on how to change the kernel mode using the graphical interface, see Mathematical Engine.

Note: Command-line instructions are provided in the following sections, which describe each mode and command-line option.

Run Maple using parallel kernels if you want variable assignments in one worksheet to work independently of those defined in other open worksheets. The percent character, %, refers to the result of the last computation by the kernel associated with the current worksheet.

Append -km p to the operating system command line that loads Maple. This step is normally unnecessary because Maple runs using parallel kernels by default.

Run Maple using a shared kernel if you want variable assignments defined in one worksheet to apply to all open worksheets. In addition, the percent character, %, refers to the result of the last computation by the kernel regardless of the worksheet in which you performed the command.

Append -km s to the operating system command line that loads Maple.

Run Maple using a mixed kernel if you want some worksheets to share a kernel and others to run using parallel kernels. Those sharing a kernel have the behavior described in Start Maple Using a Shared Kernel. Those using a parallel kernel have the behavior described in Start Maple Using Parallel Kernels.

Each time you open a new instance of Maple, a dialog will appear in which you can specify the kernel, either New or KernelConnection: Server # for all kernels that are currently active.

Append -km q to the operating system command line that loads Maple.
