The Environment type exposes the following members.

Properties

  NameDescription
Finalized
Determine whether the MPI environment has been finalized.
HostRank
Returns the rank of the "host" process, if any.
Initialized
Determine whether the MPI environment has been initialized.
IORank
Returns the rank of the process (or processes) that can perform I/O via the normal language facilities. If no such rank exists, the result will be null; if every process can perform I/O, this will return the value anySource.
IsMainThread
Determines whether the calling thread is the main MPI thread. Will return true for the thread that called the Environment constructor to initialize MPI. The main thread is particularly important when the threading mode is Funneled, because in that model only the main thread can invoke MPI routines.
IsTimeGlobal
Determines whether the Time value is synchronized across all MPI processes (i.e., if Time is a global value).
MaxTag
Returns the maximum allowed tag value for use with MPI's point-to-point operations.
ProcessorName
Returns the name of the currently executing processor. This name does not have any specific form, but typically identifies the computere on which the process is executing.
Threading
The level of threading support provided by the MPI library.
Time
Returns the time, in seconds, since some arbitrary time in the past. This value is typically used for timing parallel applications.
TimeResolution
Returns the resolution of Time, in seconds.
