Greetings,
I have compiled my code on a machine with a single CPU. Then to check if it
runs on a cluster I ran it with mpirun -np 4 on a single CPU.
I use lamboot with no options to start the network. The result is that four
processes start but they all have the same 0 rank, and there is no communication
between processes.
Then I tried to use a cluster but results were the same: four processes with 0
rank.
It seems that some settings are incorrect.
A partial output from run is below:
4776 /home/gregory/linux/test-mpi.exe running on n0 (o)
4777 /home/gregory/linux/test-mpi-exe running on n0 (o)
4778 /home/gregory/linux/test-mpi-exe running on n0 (o)
4779 /home/gregory/linux/test-mpi.exe running on n0 (o)
In addition I am sending laminfo and test(command file) files
There is also a problem setting environment variables.
I have tried two lines in the test.com with no effect
mpirun -x INBOUND,INMESH,INFLOW,INTURB
mpirun -x OUTBOUND,OUTMESH,OUTFLOW,OUTURB,OUTSUMM,OUTCONV
