[This is preliminary documentation and is subject to change.]

Scatters data from one process (the "root" process) to all of the processes in a communicator, with different parts of the data going to different processes. Unlike MPI_Scatter(IntPtr, Int32, Int32, IntPtr, Int32, Int32, Int32, Int32), different processes may receive different amounts of data. See Scatter<(Of <(T>)>)(array<T>[]()[], Int32).

Parameters

sendbuf
Type: System..::.IntPtr
Buffer containing the data to be sent. Only significant at the root process.
sendcounts
Type: array< System..::.Int32 >[]()[]
An array whose ith element contains the number of elements to send to process i. Only significant at the root process.
displs
Type: array< System..::.Int32 >[]()[]
An array whose ith element contains the offset (into sendbuf) if the data to be sent to process i. Only significant at the root process.
sendtype
Type: System..::.Int32
The type of data in sendbuf. Only significant at the root process.
recvbuf
Type: System..::.IntPtr
A buffer that will receive the calling process's part of the data.
recvcount
Type: System..::.Int32
The number of elements to receive.
recvtype
Type: System..::.Int32
The type of data to receive.
root
Type: System..::.Int32
The rank of the "root" process, which supplies the data.
comm
Type: System..::.Int32
The communicator over which the data will be scattered.
