Huh - well, the man page is definitely wrong. We ignore all other app information on the command line, but not the MCA parameters.

Hi,
 
The man page said all other command line options will be ignored if --appfile used. 
 
So just wondering 
 
1.  how to specify  "--mca btl ^sm " option while launching MPMD applications with --appfile? 
 
2. how to know the option "--mca btl ^sm "  worked?
 
Appreciating your kindly help
 
Jianyu
