parallel execution

The serial execution cost of the query is not high enough to consider an alternative , parallel execution plan .

The ideal threshold for choosing between sequential and parallel execution is a function of the cost of coordinating the parallel tasks.

GridShell allows each task in a parallel execution further control of its execution role through environment variables.

In the meantime, with the parallel execution of misuse detection and anomaly detection, the system efficiency is greatly improved.

in most cases, a query involves some operators that either cannot be parallelized, or that slow down parallel execution.

Applications that benefit from increased parallel execution are the type that divide the problem into multiple smaller tasks.

As the task size increased, so did the difference in execution time between remote parallel execution and local execution.

That is, it always initiates parallel execution (unless it has just a single outgoing sequence flow, of course).

VLIW chips don't need most of the complex control circuitry that superscalar chips must use to coordinate parallel execution at runtime.

Remote parallel execution was not favorable for smaller tasks because the overhead for communication between the machines was significant.

A serial execution plan is considered faster than any possible parallel execution plan for the particular query.

The principal benefit of using the fork-join technique is that it affords a portable means of coding algorithms for parallel execution.

If both branches are triggered, the inclusive decision leads to a parallel execution of Task 2 and Task 3 in the same way as a fork.

The second HPC pattern, divide-and-conquer, is also known as highly parallel execution.

Keyword to indicate resource requirements for selecting the hosts for parallel execution.

The parallel branches are joined again in a join, which ends the parallel execution.

Added information about when the query optimizer does not use a parallel execution plan.

For more information about parallel execution, see Degree of Parallelism.

If an application needs true parallel execution of commands against a server, multiple connections should be used.

On my parallel VM, VM features are thread-free, this means that parallel execution is available.

Flow-based processes are those that allow parallel execution of activities.

This means that remote parallel execution consumed less time on larger tasks.

Parallel execution can also be modeled using the Fork construct.

The SQL Server optimizer will use a parallel execution plan to return results if the load on the server will not be adversely affected.

However, some operators, such as sorting and scanning, can still benefit from parallel execution.

For these queries, SQL Server inserts exchange operators into the query execution plan to prepare the query for parallel execution.

The reason is that the synchronized block in Listing 5 prevents parallel execution.

During query optimization, SQL Server looks for queries or index operations that might benefit from parallel execution.

Each query in the request may start multiple threads (tasks), if a parallel execution plan is used.

With goroutines, parallel execution of code is easy.

Similarly, a task may wish to wait on input data from another task in the parallel execution of a command by specifying the

The SQL Server query optimizer does not use a parallel execution plan for a query if any one of the following conditions is true

A Parallel Execution Oriented Global Illumination Algorithm

To prevent a parallel execution plan from being generated on this query, create the following plan guide

The stop node in parallel execution branches
