 * instead of blanket operation. In most cases, the party that started the grid instance
 * should be responsible for stopping it.

 * Note also that restarting functionality only works with the tools that specifically
 * support Ignite's protocol for restarting. Currently only standard <tt>ignite.{sh|bat}</tt>
 * scripts support restarting of JVM Ignite's process.
 *
 * @param cancel If {@code true} then all jobs currently executing on
 *      all grids will be cancelled by calling {@link ComputeJob#cancel()}
