I have not tried these doing this with Swift/T on a Cray yet.
However, it should not be too hard. <br>
<br>
I assume you are using Turbine's provided aprun.sh script. You
can also use the new (as of last week) turbine-aprun-run script,
which may be easier to use. Documentation for the new script is
here:
<a class="moz-txt-link-freetext" href="http://www.mcs.anl.gov/exm/local/guides/turbine-sites.html#_raven">http://www.mcs.anl.gov/exm/local/guides/turbine-sites.html#_raven</a><br>
<br>
In either case, you will need to edit the script and modify the
aprun line to do what you want. On the Cray, do a "man aprun" to
see what your options are. I think the key argument you need is
-cc . The Examples section has some (13!) use cases. When trying
examples in Swift/T, you can edit the first lines of your
STC-generated Tcl script to print the hostname or other things for
debugging. <br>

<div>I was just wondering. When I run a multinode Swift
application and give it 2 workers and 2 nodes on Raven, is
there some way to force each worker to run on a separate node?
For an initial test I would like to map 1 worker per GPU
node.</div>
<div><br>
</div>
<div>Any tips on how I might be able to control how the workers
are established?</div>
