[Mpi-22] reConfigurable MPI

[siavash ghiasvand]

Hi,

In MPI22 Standard document
[*1*<http://www.mpi-forum.org/docs/mpi-2.2/mpi22-report.pdf>]
on page 305 lines 27-30 we can see this paragraph:

> The MPI Forum decided not to address resource control because it was not
> able to
>
design a portable interface that would be appropriate for the broad spectrum
> of existing
>
and potential resource and process controllers. Resource control can
> encompass a wide
>
range of abilities, including adding and deleting nodes from a virtual
> parallel machine, ...
>

Which means, an MPI-based cluster is not reconfigurable at run time! but in
EuroPVM/MPI 2006 a reconfigurable version of MPI for HPC clusters was
described by University of New Mexico Scalable Systems Lab
[*2*<http://www.pvmmpi06.org/talks/CommProt/venkata.pdf>]
and they show that their implementation will enhance performance (the main
goal of MPI). So, why in MPI22 standard "*The MPI forum decided not to
address resource control*" which can improve both flexibility and
performance of an MPI-based cluster?
