Article
04/22/2013

Submits a LINQ to HPC query to an HPC cluster so that the query can run on records from a DSC file set.

Namespace: Microsoft.Hpc.Linq
Assembly: Microsoft.Hpc.Linq (in Microsoft.Hpc.Linq.dll)

Usage

'Usage
Dim source As IQueryable(Of TSource)
Dim returnValue As HpcLinqJobInfo

returnValue = HpcLinqQueryable.Submit(source)

Syntax

'Declaration
<ExtensionAttribute> _
Public Shared Function Submit(Of TSource) ( _
    source As IQueryable(Of TSource) _
) As HpcLinqJobInfo

[ExtensionAttribute] 
public static HpcLinqJobInfo Submit<TSource> (
    IQueryable<TSource> source
)

[ExtensionAttribute] 
public:
generic<typename TSource>
static HpcLinqJobInfo^ Submit (
    IQueryable<TSource>^ source
)

J# supports the use of generic APIs, but not the declaration of new ones.

JScript does not support generic types or methods.

GenericParameters

TSource
The type of the records in the source parameter.

Parameters

source
A System.Linq.IQueryable<TSource> interface for the query that you want to run.

Return Value

A HpcLinqJobInfo that contains information about the job that is created to run the query on the HPC cluster.

Exceptions

Exception type	Condition
ArgumentNullException	The specified source parameter is a null reference (Nothing in Visual Basic).

Remarks

The Submit method blocks the thread from running only until the HPC Job Scheduler Service creates the job that runs the query. The Submit method does not wait for the job to complete, but returns an instance of a HpcLinqJobInfo object that you can use to track the progress of the job. To submit the query and block the thread until the job that runs the query completes, use the SubmitAndWait method instead.

Use the GetEnumerator method or the foreach statement of the C# language (For Each in Visual Basic) to get the results of the query.

In Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Platform Note: This method was introduced in Windows HPC Server 2008 R2 with Service Pack 2 (SP2) and is not supported in previous versions.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
