This paper presents a novel concept of multi-drop path-based multidestination message passing on switch-based irregular networks. First, the multi-drop mechanism is deened with an associated header encoding scheme, and this mechanism is used to develop path-based multidestination worms. Next, a method is proposed to identify valid multidestination paths on arbitrary irregular networks with a ty...

Wave-equation based shot-record migration provides accurate images but is computationally expensive because every shot must be migrated separately. Shot-encoding migration, such as random shot-encoding or plane-wave migration, aims to reduce the computational cost of the imaging process by combining the original data into synthesized common-source gathers. Random shot-encoding migration and pla...
