Hi,
I have difficulty catching std::bac_alloc in an MPI environment. The code
is attached. I'm uisng gcc 6.3 on SUSE Linux Enterprise Server 11 (x86_64).
OpenMPI is built from source. The commands are as follows:
*Build*
g++ -I -L -lmpi memory.cpp
*Run*
-n 2 a.out
*Output*
0
0
1

Jeff,
Thanks for the explanation. It's very clear.
Best regards,
Zhen

Does this mean there's an additional thread to transfer data in background?

Hi,
I'm having a problem with Isend, Recv and Test in Linux Mint 16 Petra. The
source is attached.
Open MPI 1.10.2 is configured with
./configure --enable-debug --prefix=/home//Tool/openmpi-1.10.2-debug
The source is built with
~/Tool/openmpi-1.10.2-debug/bin/mpiCC a5.cpp
and run in one node
