This issue is with the implementation of MPI in Microsoft MPI.NET 9.0 where if there is a single node to communicate with that scatter does not correctly transmit the single value sent. If more than one node is being transmitted to then this bug does not occur. A workaround for this issue where only a single node is required is to use use the send method.

There seem to be some issues when trying to compile MPIdotNet for linux.

Firstly, autogen.sh nearly works, but during step automake it tries to find a directory with name MPIUtils, which doesn't exist.
I'm unsure of what the Makefile in this directory is supposed to do, or what other things it should/did contain, but removing the entries referencing it in both Makefike.am and configure.ac seems to make the autoconf run successfully.
If, however, this folder contains something important, that probably needs to be fixed too.

Secondly, the configure-script looks for gmcs, which is deprecated and no longer possible to install. Replacing it would mean looking for either dmcs, which is also deprecated but created as a shortcut upon installing mcs, or just look for mcs to begin with.

Lastly, or rather as far as I've come, running make crashes on it''s first line;

This is where I've become stuck, as it's an issue I'm unsure of how to fix.

I'm trying to build this on 4.7.1, but is failing with following error:

C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets(1098,5): error MSB3644: The refe
       rence assemblies for framework ".NETFramework,Version=v4.6.2" were not found. To resolve this, install the SDK o
       r Targeting Pack for this framework version or retarget your application to a version of the framework for which
        you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Ca
       che (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly target
       ed for the framework you intend. [c:\MPI.NET\Benchmarks\Netcoll_cs\Netcoll_cs.csproj]

The version (4.6.2) seems to be hardcoded in the project file(s). Is this a strict dependency? Can I build this on systems with later versions?
