hkaiser: sorry, here now
<jgurhem>
Hi ! simbergm I had a few mistakes in my computation of the indices. I also had a few issues with copies and constructors for my partition_data.
<simbergm>
all right :) and you managed to run it on multiple nodes without problems?
<jgurhem>
I'm now trying to launch my HPX application in a distributed env but I don't know what to pass to HPX
<simbergm>
I think sadly we don't have any documentation that explicitly tells you that
<jgurhem>
There is the description of the command line options...
daissgr has joined #ste||ar
<simbergm>
jgurhem: right, if that's good enough for you I'm happy
<simbergm>
I know many people would be unhappy with it ;)
<jgurhem>
simbergm: I'm not happy with it !
<jgurhem>
I does not work
<jgurhem>
I'm running 48 times the same app instead of 16 threads on 3 nodes
<jgurhem>
Still some work
<jgurhem>
simbergm: In the post you show me hkaiser: is mentionning a second option with mpirun with special build instructions. Do you know them ?
<simbergm>
jgurhem: I haven't tried it myself but I think that's supposed to work the same as with any other batch environment that we support, i.e. without you having to do anything
<simbergm>
how are you launching it at the moment to get 48 processes?
<simbergm>
or you use hpxrun.py (it's in the tools folder)
<simbergm>
you have mpi enabled, no?
<simbergm>
or the mpi parcelport, to be precise
<simbergm>
HPX_WITH_PARCELPORT_MPI=ON
<jgurhem>
I'm compiling HPX with HPX_WITH_PARCELPORT_MPI=ON rigth now. I'll try again when it's done
<jgurhem>
I was using mpirun in a job submitted to LoadLeveler
<simbergm>
ok, mpirun is probably launching one process per thread rather than one process per node by default, so you might have to force it to change that
<jgurhem>
There is no hpxrun.py file in hpx/tools
<simbergm>
don't know the command line parameters for that though, sorry :/
<simbergm>
right, sorry
<simbergm>
if you've installed hpx it's in the bin folder
<simbergm>
(forgot that it's generated)
<simbergm>
or in the bin folder of the build directory actually...
