[mpich-discuss] Generalized request classes

[Matthieu Dorier]

Hi, 


Is there any hope that the currently non-standard generalized request interface (MPIX_Grequest_*) in mpich eventually becomes part of the standard (or something that looks like this API)? 
I just spent two days hopelessly trying to develop something with the standard generalized requests, but gave up: this API is basically useless unless a thread is used to do the MPI_Grequest_complete. 


For information, what I was trying to do was a custom version of MPI_Iprobe that takes an MPI_Request* parameter instead of a int* flag and an MPI_Status*, in order to be able to call MPI_{Wait,Test}{all,any,some} on requests generated by different types of non-blocking operations including MPI_Iprob. (btw, is there a reason why MPI_Iprob doesn't have this signature already? That would have make more sense, in my opinion).
