Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

If misalignment is the case then adding "sequence" to the data type might help. So: type :: sequence integer :: ... real :: ... end type Note that you cannot use the alignment on types with allocatables and pointers for obvious reasons. 2014-10-03 0:39 GMT+00:00 Kawashima, Takahiro

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

Dears, First of all. Really really thanks for you help, I am learning a lot. Second: I try to study the MPI_TYPE_CREATE_STRUCT and all the things look correct. I use Intel Fortran compiler and when I compile with -r8 means that I am compiling in double precision. About Nick suggestion: Coding

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

I would never compile a fortran program relying on a specific compiler option! I would never use r8/i8! I would highly encourage you to explicitly set the precision of each variable if you need specific variable precision. There are plenty of tutorials around for this (selected_real/int_kind).

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

Dear all, dear Nick, thanks lot. I have understood something, so I have create this variable type: TYPE tParticle SEQUENCE INTEGER :: ip INTEGER :: fake REAL:: RP(2) REAL:: QQ(4) END TYPE tParticle In the point number 2, do you mean to insert some align options?

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

Dear Nick, thanks again. After reading your post I have thought to compile as mpif90 -r8 *.f90 and to have this type variable TYPE tParticle SEQUENCE INTEGER :: ip INTEGER :: fake REAL:: RP(2) REAL:: QQ(4) END TYPE tParticle where I use fake to have 4 + 4 bytes, and

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

Well it says MPI_ERR_TYPE: invalid datatype so I guess you have done something wrong. ;) You should debug as much as you can your self. 1) Check that your type-creation calls actually proceed as expected 2) Check that your type-commit actually proceed as expected 3) Telling us that "it is not

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

Dear Nick, thank you, The important things is that the MPI_TYPE_CREATE_STRUCT works. Now I will proceed with the debug by myself, I will check MPI_TYPE_CREATE_STRUCT ierr output and other part of my program. Again thanks you Diego On 3 October 2014 15:45, Nick Papior Andersen

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

Might I chip in and ask "why in the name of fortran are you using -r8"? It seems like you do not really need it, more that it is a convenience flag for you (so that you have to type less?)? Again as I stated in my previous mail, I would never do that (and would discourage the use of it for almost

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

Dear Jeff, Dear Nick, the question is about, inserting the FLAG for using -r8 Now I have written a simple code with select_kind to avoid -r8. I get the same error. You can find the code in the attachment. probably there is something wrong with ompi configuration What do you think? Again,

Re: [OMPI users] SENDRECV + MPI_TYPE_CREATE_STRUCT

Diego, I strongly suggest a careful reading of the Datatype chapter in the MPI 3.0 standard. More precisely, the example 4.18 might be of particular interest in your case, as it explains everything that you need to do in order to obtain a portable datatype, one that works in all cases
