The conversion of the seam tapes from their original simple joining task to backup use over heat-welded seams and, finally, with reinforcing filaments, to the primary structural load-bearing factor enabled further size increases and advanced reliability.
In environments where multiple queries with similar selection predicates, common tables, and join tasks arrive simultaneously, many opportunities can arise for sharing scan and/or join computation tasks.
Over time, the number of JTTFs increased, improving coordination with state and local officials and even other elements of the intelligence community, as C.I.A. officers joined several task forces.
On 12 and 13 April, the BPF switched targets to airfields in northern Formosa and her sister joined the task force on 14 April.
Shadowing American submarines tracked the Japanese fleet into the Philippine Sea as Admiral Spruance joined his task force with Admiral Mitscher's to meet the enemy.
Following the shore bombardments, Indiana joined the task force that had assembled to invade Okinawa; the ship provided ground support fire as well as anti-aircraft defense against the increasing number of Kamikazes that were attacking the invasion fleet.
From these models, the fork-join task model (see Fig. 1) is the simplest in terms of parallel structure.
This figure depicts a fork-join task with its fork points (ϕ 1 and ϕ 2), synchronization points (μ 1 and μ 2), and its slack time.
Three task models supporting intra-task parallelism exist in the real-time systems domain: (1) the fork-join task model, (2) the synchronous task model, and (3) the directed acyclic graph (DAG) task model.
In this figure, it is possible to observe the task structure of a fork-join task (left side), its timing properties (upper right side), and its serialized representation (lower right side).
