Dear Community,

I am struggling to run Fluent in distributed parallel on Linux.  (I have done this for decades on Windows.)  Below is a list similar to the error messages I am getting.  (I dont have my solver available now to copy the exact messages, but these contain the main context.)  I have repeatedly assigned the environment variable MPI_IB_PKEY = 0x8008 in the GUI, but nothing changes.  When I look at the script that ANSYS automatically generates at the command line when I fire up the GUI, it has other environment variables but not the one I entered.  I also tried this command, but nothing improved:  export MPI_IB_PKEY="0xffff".  Thank you in advance for your advice. 

Rank 05: MPI_Init_thread: multiple pkey found in partition key table, please choose one via MPI_IB_PKEY

Rank 05: MPI_Init_thread: pkey table:

Rank 05: MPI_Init_thread: 0x8001

Rank 05: MPI_Init_thread: 0x7fff

 

 

Rank 0:25: MPI_Init_thread: Can't initialize RDMA device

Could you post screenshots of the page that you add the environment variable , the beginning of console output once you start the Fluent GUI , and the command line once you start the GUI ?

Thank you Win very much for your feedback.  We found a workaround without further diagnostics, so I am going to call this "solved".
