Hello, all!
I implement MPI for our computer, and have a question about definition
some functions (MPI_TEST, MPI_TEST_ANY, etc).
In MPI Version 1.1 June 1995 p. 42 is written "One is allowed to call
MPI_TEST with a null or inactive request argument. In such a case operation
returns with flag=true and empty status."
We check completion of action that is not started. There are three variants
of behavior in
such case:
1. action is not complete (flag=false)
2. action complite (flag=true)
3. error
Can anybody explain choice that was made.
Thanks!
Victor.
