Hi,
It seems that OMPI_MCA environment variables with spaces (for rsh?) are
incorrectly escaped.
This happens with version 1.8 and 1.8.1. I did not try Version 1.7!
To reproduce:
0) ./configure && make && make install # no special configure flags required
1) Create a host file, with a couple of hostnames in it.
2) export OMPI_MCA_mpi_show_handle_leaks="1 --foo"
3) mpirun -hostfile /path/to/hostfile -n 1 /code/to/mpi.exe
Expected:
--------------------------------------------------------------------------
An invalid value was supplied for an enum variable.
Variable : mpi_show_handle_leaks
Value : 1 --foo
Valid values : 0: f|false|disabled, 1: t|true|enabled
--------------------------------------------------------------------------
...
Actual:
orted: Error: unknown option "--foo"
Type 'orted --help' for usage.
Usage: orted [OPTION]...
-am <arg0> Aggregate MCA parameter set file list
...
A potential patch that fixes the problem (but then I don't know why ";"
would be considered a special character in the first place).
