Just a piece of data, the ib_send_lat test from the perftest pkg (OFED) claims
to be able to run on UD (from -h output):

 Usage:
   ib_send_latstart a server and wait for connection
   ib_send_lat  connect to server at 

 Options:
   -p, --port=Listen on/connect to port  (default 18515)
   -c, --connection=  Connection type RC/UC/UD (default RC)
 ...

I'm unaware of any work at all with the ofud BTL in the past several years, so 
I'd suspect not.

[OMPI devel] getting started with grid engine integration

2011-05-03 Thread Maurice Feskanich 

All,

My team has been tasked with integrating our grid engine with Open MPI.  
I'm looking for information that would shed light on how this is done.  
In essence, I need to integrate the way LSF or SGE is integrated.  I've 
looked at the FAQ, and nosed around in the code, but I don't have a 
clear idea of which APIs to implement, or where my plugins would be used.


Any and all pointers will be much appreciated,

Maury Feskanich

Be happy to provide advice. Without knowing anything about your grid engine, 
it's a tad difficult to know exactly what you need. In the case of SGE, all 
that was required was to identify a few envars and point the rsh launcher to 
"qrsh". For LSF, it took a little more work.

There are three main frameworks generally involved:

1. ras - determines what nodes are being used for this job. You'll see a 
"gridengine" plugin there that might serve as a model - it supports SGE.

2. plm - actually launches the ORTE daemons on the remote nodes. You might need 
your own, or you might be able to piggy-back on rsh the way SGE did - all 
depends on the specifics of your launcher.

3. ess - this contains whatever logic required by the launched daemons to 
identify their process name. If you have a launcher like SGE's, then the name 
is provided on the daemon cmd line, so no plugin is required. If you launch 
like LSF, which uses a batch launch method, then the daemons typically use 
something in their environ to determine their name - and a plugin would be 
required.

Each framework is in its respective orte/mca/xxx directory, with each plugin 
appropriately named underneath that directory. You'll also find an xxx.h file 
in each framework that describes the API that each plugin must support - often, 
though, it is easier to understand that API by just using one of the existing 
plug-ins as an example.

HTH - feel free to ask questions.
