Fortran datatypes for MPI_Window attributes
by Jeff Squyres (jsquyres) 28 Apr '16

28 Apr '16

Fortran WG -- An issue came up in Open MPI recently; I just created a Github issue for the RMA WG: https://github.com/mpiwg-rma/rma-issues/issues/1 I'm letting you know because it has to do with the Fortran datatypes of attributes on MPI windows. -- Jeff Squyres jsquyres(a)cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/

Re: [MPIWG Fortran] Deprecate MPI_SIZEOF in MPI-4.0

Jeff and Craig, I'm also good with this, but technically, in my opinion, the following changes are needed: - Page 604, lines 19-20 of https://github.com/mpi-forum/mpi-issues/files/221301/mpi-report-deprecate-m… read The following Fortran subroutines are deprecated; the Fortran language storage_size() and c_sizeof() intrinsic functions provide this functionality. but should read (proposal) The following Fortran subroutines are deprecated; the Fortran language storage_size() and c_sizeof() intrinsic functions provide similar functionality. Whereas MPI_SIZEOF() and c_sizeof() provide the size in bytes, the intrinsic storage_size() provides the size in bits. Otherwise it is a direct path to the hell when people updating there deprecated source code. - Page 631, lines 5-8 read MPI_TYPE_MATCH_SIZE can be used to obtain a size-specific type that matches a Fortran numeric intrinsic type by first calling storage_size()in order to compute the variable size, and then calling MPI_TYPE_MATCH_SIZE to find a suitable datatype. In C, one can use the C function sizeof(), instead of storage_size(). It is necessary to mention that storage_size() returns bits and not bytes. It should be written in a way that a Fortran reader Need not to read the C text and vice versa. Proposal: MPI_TYPE_MATCH_SIZE can be used to obtain a size-specific type that matches a Fortran numeric intrinsic type by first calling storage_size() in order to compute the variable size in bits, deviding it by 8, and then calling MPI_TYPE_MATCH_SIZE to find a suitable datatype. In C, one can use the C function sizeof(), which returns the size in bytes, instead of storage_size() (which returns the size in bits). - On page 18 in Table 2.1 the following mail should be added: MPI_SIZEOF MPI-4.0 ____ storage_size() 5) With footnote 5) Fortran intrinsic. It returs the size in bits instead of bytes. - In the General index on page 721, I would recommend to add the keyword "MPI_SIZEOF and storage_size()" and all Locations of the both routines.

Deprecate MPI_SIZEOF in MPI-4.0

We brought this up forever ago (December 2014), and never progressed the issue (IIRC). It came up again today in a different context (in the Open MPI community). So I took the liberty of re-creating the issue in the Github MPI Forum system: https://github.com/mpi-forum/mpi-issues/issues/51 We still want to move forward with this, right? -- Jeff Squyres jsquyres(a)cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
