Intel MPI and DAPL

Developer Software Tools Intel® MPI Library
1

I am migrating MPI application written for Linux to Windows (Windows 2008 server). I downloaded the MPI
Library Kit for eval. I am also using Mellanox WinOF for Windows.

I am getting “DAPL provider is not found and fallback device is not enabled” when I
run:

mpiexec -n 4 -env I_MPI_DEBUG 100 -env I_MPI_FALLBACK_DEVICE 0 -env I_MPI_DEVICE rdma::ibnic0v2 HelloWorld.exe

I would like to know how to configure; so that I can run with I_MPI_DEVICE rdma.

Thanks

Hi Warenne,

The command line is correct, but why do you use 2 colons in *“rdma::ibnic0v2”?

Is dat.dll accessible through %PATH% variable?

I’ve check dat.conf on our server and I see the full path to any dll in this file.

Best wishes,

Hi Dimitri,

Thank you foryour response. I have several more questions:

(1) Which interface adapter in the dat.conf should I use for Mellanox ConnectX WinOF?

(2)What doesI_MPI_NETMASK and I_MPI_DEVICE doif I specify both of them?

(3) Can you provide mea checklist to verify whether my configuration is correct or not?

(4) I retried the command with the following changes:
(a) Add path for both “dat.conf” and “dat.dll” to %PATH%
(b) Remove “::ibnic0v2” from the command
(c) Modified “c:Datdat.conf” to include path to the dlls.

I still am getting the same error. Here is the output from the run.

Hi Warenne,

1. ibnic0v2 should be OK.
2. try to disable I_MPI_NETMASK for a while.
3. could you try ‘dapltest.exe’? This utility should show you a correct adapter.
4. dat.conf on our server looks like:

# DAT v1.1 dapl provider configuration for HCA0 port 1
ibnic0 u1.1 threadsafe default C:Windowsdapl.dll ri.1.1 “IbalHca0 1” “”
IbalHca0 u1.1 threadsafe default C:Windowsdapl.dll ri.1.1 “IbalHca0 1” “”

# DAT 1.1 debug
ibnic0d u1.1 threadsafe default “C:\Program Files (x86)\WinOF\dapld.dll” ri.1.1 “IbalHca0 1” “”

# DAT 2.0
ibnic0v2 u2.0 nonthreadsafe default C:Windowsdapl2.dll ri.2.0 “IbalHca0 1” “”
IbalHca0v2 u2.0 nonthreadsafe default C:Windowsdapl2.dll ri.2.0 “IbalHca0 1” “”

# DAT 2.0 (debug)
ibnic0v2d u2.0 nonthreadsafe default “C:\Program Files (x86)\WinOF\dapl2d.dll” ri.2.0 “IbalHca0 1” “”

# DAT 2.0 [socket-cm] InfiniBand QPs setup by passing QP info over a socket
# connection; supports DAT Windows <==> Linux over IB connections.
ibnic0v2-scm u2.0 nonthreadsafe default C:Windowsdapl2-scm.dll ri.2.0 “IbalHca0 1” “”

# Socket-CM (debug)
ibnic0v2-scmd u2.0 nonthreadsafe default “C:\Program Files (x86)\WinOF\dapl2-scmd.dll” ri.2.0 “IbalHca0 1” “”

5. Have you installed Intel MPI? Did you use ‘mpivars.bat’

6. To test the installation:
- Verify through the Computer Management that the smpd service is started. It calls the Intel MPI Process Manager.
- Verify that ia32bin (em64tbin for the Intel 64 architecture in the 64-bit mode) is in your path:
> echo %PATH%
You should see the correct path for each node you test.
> mpiexec.exe -hosts 2 host1 1 host2 1 a.bat
where a.bat contains
echo %PATH%

Run the test program with all available configurations on your cluster.
+ Test the sock device using:
> mpiexec.exe -n 2 -env I_MPI_DEBUG 2 -env I_MPI_DEVICE sock test.exe You should see one line of output for each rank, as well as debug output indicating that the sock device is used.
+ Test the ssm devices using:
> mpiexec.exe -n 2 -env I_MPI_DEBUG 2 -env I_MPI_DEVICE ssm test.exe
+Test the rdma device using:
> mpiexec.exe -n 2 -env I_MPI_DEBUG 2 -env I_MPI_DEVICE rdma test.exe

Please let me know which configuration works for you.

Try to start your HelloWorld.exe without I_MPI_FALLBACK_DEVICE.

Seems that something wrong with your environment, but it’s hard to find out what it is exactly.

Regards!
Dmitry
