I try to run my program using the following commands mpiexec -n 2 -hosts 2 MACHINE-01 MACHINE-02 mpitest_c.exe However, it prompts me saying that the dapl fabric is not available. I have verified that the Mallanox WinOF is installed. However, I cannot find the file /etc/dat.conf. Is it being renamed and placed in other directories? Or is there other issues that I need to take note of? Thanks.
With only 2 nodes, wouldn't rdma be better than dapl? I assume you have it working with socks.
Hi,
The correct command line should look like:
mpiexec -hosts 2 PHITEN-01 #of_processes1 PHITEN-02 #of_processes2 mpitest_c.exe
In your case it should be:
mpiexec -hosts 2 PHITEN-01 1 PHITEN-02 1 mpitest_c.exe
dat.conf may be located in different directories - it depends on your installation. Please check "c:\DAT" directory.
WinOF may also be located in different directories but usually it resides in "c:\program files\winof"
Regards!

Good Day, I have discovered that Mallanox WinOF 2.0.7 on Windows 2003 does not have the DAT functionality. What I have done is to install the generic installer that is available in OpenFabrics Alliance. The url ishttp://www.openfabrics.org/index.php?option=com_content&view=article&id=56&Itemid=121 But remember to update the firmware for your HCA connector. Thanks.
Thanks, Aaron, for sharing with us!
