Re: [OMPI users] Whether to use the IB BTL or not

In addition to what Howard said, there's actually two other metrics that are used, as well. Each BTL exports a priority and an exclusivity value. IIRC (it's been a while since I've looked at this code), the PML gathers up all BTL modules that claim that they can communicate between a pair of

Dear Gilles, Thanks, Thanks a lot. Now is more clear. Again, thanks a lot Diego

Diego, The compiler likely added some padding after %ip to have data aligned on 128 bits. You need two dummies in case the compiler adds some padding at the end of the type. Cheers, Gilles Diego Avesani さんのメール: >Dear Gilles, Dear all, > >thanks, thanks a lot. > >

Re: [OMPI users] OMPI users] MPI_Type_Create_Struct + MPI_TYPE_CREATE_RESIZED

Dear Gilles, Dear all, thanks, thanks a lot. Could you explain it to me, please? I mean, when I print displacements I get: displacements(0)= 6922656 displacements(1)= 0 displacements(2)= 16 displacements(3)= 48 displacements(4)= 112 Why do I have 16 spaces in displacements(2), I have only an
