I'll start a new thread.
this all involves LAM 6.0 with 15 patches

I have solved the problem of not being able to have the mpi job read stdin.

mpirun ... -i <path>/input does not do it
mpirun ... -i input does not do it

I had to change the program to open the input file by name.  That works.

Now I get the following error message -

 MPI_Isend: internal MPI error: GER overflow (rank 0, comm 0) 

What is GER?

I tried increasing buffer size with bfctl but that has no effect.  In fact it
doesn't change the value.

I do a bfctl -s 0x10000000 n0 then a bfstate -l n0
i get -
 NODE      DEST      EVENT    TYPE     LENGTH
n0 (o)    max space = 268435456, used space = 0

Then I run the job with mpirun and do a bfstate -l n0 and it's back to default.
NODE      DEST      EVENT    TYPE     LENGTH
n0 (o)    max space = 8388608, used space = 0

It appears that mpirun resets the buffer space ?? Is that true?

If so, how can I increase the buffer space, assuming that is the cause of the
MPI_Isend error.

Thanks.
