Hello,
I'm a lam user looking to switch to openmpi, and having trouble
compiling. I hope someone here can give me a hint!
So configure works fine, as does make up to this point:
g++ -O3 -DNDEBUG -fno-inline -pthread -o .libs/ompi_info components.o
ompi_info.o output.o param.o version.o -Wl,-
It would be nice if the c++ compiler wrapper were
installed under mpicxx, mpiCC, and mpic++ instead of
just the latter 2.
Also on the fantasy wish list is for the libraries to
be installed in libtool form (unless you go away from autotools
altogether).

Just a brief response on two points (lest the 'insiders' think
there are no sympathetic outsiders...).

It appears it could be extended to include useful bits of info
that are normally classed as build magic.
e.g. gnome-config, xml2-config, etc, etc.
I see lam-config was debated at least briefly back in 2

How are we meant to free memory allocated with MPI_Win_allocate()? The
following crashes for me with OpenMPI 1.10.6:
#include
#include
#include
int main(int argc, char **argv) {
MPI_Init(&argc, &argv);
int n = 1000;
int *a;
MPI_Win win;
MPI_Win_allocate(n*sizeof(int), sizeof(int),
MPI_Accumulate() is meant to be non-blocking, and MPI will block until
completion when an MPI_Win_flush() is called, correct?
In this (https://hastebin.com/raw/iwakacadey) microbenchmark,
MPI_Accumulate() seems to be blocking for me in OpenMPI 1.10.6.
I'm seeing timings like
[brock@nid00622 junk
Is there any way to issue simultaneous MPI_Accumulate() requests to
different targets, then? I need to update a distributed array, and this
serializes all of the communication.

Futhermore MPI_SEND and MPI_RECEIVE are called a dozen times in only one
source file (used for passing a data structure from one node to another) and
it has proved to be working in every situtation.
Not knowing which line is causing my segfault is annoying. [?]

I'd like to stress that in both cases MPI_INTEGER size is 4-bytes long.
I'll follow my own intuition and Jeff's advice that is using the same flags
for compiling openmpi as compiling DRAGON.

Now that I know the program doesn't work both with OMPI and MPICH2
implementations, I guess it's not dependant of MPI implementation.

Are MPI datatypes like MPI_INT and MPI_CHAR guaranteed to be compile-time
constants? Is this defined by the MPI standard, or in the Open MPI
implementation?
I've written some template code where MPI datatypes are constexpr members,
which requires that they be known at compile time. This works in
Thanks for the responses--from what you've said, it seems like MPI types
are indeed not guaranteed to be compile-time constants.
However, I worked with the people at IBM, and it seems like the difference
in behavior was caused by the IBM compiler, not the Spectrum IBM

I'm setting up a cluster on AWS, which will have a 10Gb/s or 25Gb/s
Ethernet network. Should I expect to be able to get RoCE to work in Open
MPI on AWS?
More generally, what optimizations and performance tuning can I do to an
Open MPI installation to get good performance on an Ethernet network?
Thanks for your response.
One question: why would RoCE still requiring host processing of every
packet? I thought the point was that some nice server Ethernet NICs can
handle RDMA requests directly? Or am I misunderstanding RoCE/how Open
MPI's RoCE transport?
Ben
In case anyone comes across this thread in an attempt to get RDMA over
Ethernet working on AWS, here's the conclusion I came to:
There are two kinds of NICs exposed to VMs on AWS:
- Intel 82599 VF
- This NIC is old and does not support RoCE or iWARP.
- It's a virtualized view of an actu
I used to be able to (e.g. in Open MPI 3.1) put the line
rmaps_base_oversubscribe = true
in my `openmpi-mca-params.conf`, and this would enable oversubscription by
default. In 4.0.0, it appears that this option doesn't work anymore, and I
have to use `--oversubscribe`.
