struct spmd_block

The class spmd_block defines an interface for launching multiple images while giving handles to each image to interact with the remaining images. The define_spmd_block function templates create multiple images of a user-defined action and launches them in a possibly separate thread. A temporary spmd block object is created and diffused to each image. The constraint for the action given to the define_spmd_block function is to accept a spmd_block as first parameter.
