that were set on the command line. This was techinically exactly the
way the code was designed, but it certainly violated the Law of Least
Astonishment (even to its designer ;-) ). So now if you execute
something like this:
mpirun -mca pls_rsh_debug 1 -np 4 hello
You'll see debugging output from the rsh pls component, as you would
expect (this was not previously the case -- the MCA pls_rsh_debug
parame would be set to 1 in the 4 spawned hello processes, but *not*
in the orterun process).
More specifically, MCA parameters will be set in the orterun process
in the following cases:
- The new command line switch "--gmca" (or "-gmca") is used,
indicating that the MCA parameter is "global". --gmca also means
that that MCA parameter will be applied to all context app's. For
example:
mpirun -gmca foo bar -np 1 hello : -np 2 goodbye
The foo MCA param will be set in both the hello and goodbye
processes.
- If there is only one context app. For example:
mpirun -mca pls_rsh_debug 1 -np 4 hello
will set pls_rsh_debug to 1 in both the orterun process and the 4
spawned hello processes.
Also added a few more comments inside orterun to document a somewhat
confusing use of a state variable in a recursive case.
This commit was SVN r6764.
* Add ability to completely disable libltdl (the dlopen code to load
dynamic shared objects) to configure: --disable-dlopen
* Added MCA param (component_disable_dlopen) to disable DSO loading
at runtime
* Made the event library behave in some not-completely-erroneous way
on platforms where it has absolutely no eventops support (ie, no
select, poll, or epoll)
* Disabled orte_wait, opal_few, and opal_daemon_init code on
platforms without fork, waitpid support. All non-init functions
will return OPMI_ERR_NOT_SUPPORTED
* Disable orteprobe tool when fork or pipe aren't supported
This commit was SVN r6490.
