[OMPI users] communicator with MPI_Reduce

Designation: Non-Export Controlled Content Folks; My MPI_COMM_WORLD size is 2000. I have created a communicator based on a small subset. I have used this communicator in MPI_Barrier calls and it seems to work fine. Now I want to use this in MPI_Reduce. When I do this I get

Justin -- Fair point. Can you work with Sylvain Jeaugey (at Nvidia) to submit a pull request for this functionality? Thanks. > On Oct 18, 2016, at 2:26 PM, Justin Luitjens wrote: > > After looking into this a bit more it appears that the issue is I am building > on a

You will not be able to generate VT traces, and since you unlikely want to do that, you will likely be just fine Cheers, Gilles On Wednesday, October 19, 2016, Mahesh Nanavalla < mahesh.nanavalla...@gmail.com> wrote: > Hi Gilles, > > Thanks for reply, > > If i do *--disable-vt *while

Hi Gilles, Thanks for reply, If i do *--disable-vt *while configuring the openmpi-1.10.3 , the size of the installation directory reduced 70MB to 9MB. will it effect anything? On Wed, Oct 19, 2016 at 4:06 PM, Gilles Gouaillardet < gilles.gouaillar...@gmail.com> wrote: > vt is a

vt is a contrib that produces traces to be used by VaMPIr IIRC, this has been removed from Open MPI starting v2.0.0 Worst case scenario is it will fail to build, and most likely case is you do not need it, so you can save some build time with --disable-vet Cheers, Gilles On Wednesday, October

[OMPI users] fail to run client/server mode using MPI_COMM_ACCEPT/MPI_COMM_CONNECT without mpirun

I was doing the work to integrate OpenMPI into our application, and we did not want to rely on mpirun. And it seems that singleton MPI_INIT could meet our need. So I wrote a client/sever demo to verify it. However, it did not work. Is there anything wrong here or OpenMPI does not support

Re: [OMPI users] openmpi-1.10.3 cross compile configure options for arm-openwrt-linux-muslgnueabi on x86_64-linux-gnu

Hi all it's working. I forget to copy all openmpi libs and bin to target board Now it's working fine... Thank u all. Thank u very much for your support root@OpenWrt:/# cp /openmpi/lib/libopen-rte.so.12 /usr/lib/ root@OpenWrt:/# cp /openmpi/lib/libopen-pal.so.13
