[François Tessier <francois.tessier AT inria.fr>]

Any idea?

When I run the application with the run command above, it crashes (see attachment) or, sometimes, nothing happens. If I run this with +p8, it works perfectly (the application runs fine and the load balancer is carried out on a parallel way) but, of course, only on the first node...

So, what doesn't work is to execute kNeighbor on 8 (or more) nodes, with 8 processes per node and to be able to run my parallel load balancer on the master node every n iterations.

Thanks for you help

Please be more specific - what were the *problems* that you actually encountered? Everything you described seems to be reasonable.

Did it crash? Did it hang? Did the load balancer not run in parallel? Did you get unexpected output? What happened that was wrong?

Hi!

With the help of some of you, I wrote a parallel load balancer using
CkLoop. But I encounter some problems to run an application with this
load balancer. For example, I try to do experiments with kNeighbor and I
proceeded like that :

- Build charm++ : ./build charm++ mpi-linux-x86_64-smp --with-production -j
- Go to tmp/libs/ck-libs/ckloop then make
- Compile kNeighbor with -module CkLoop

All these steps succeeded. My run command looks like :

./charmrun +p64 -machinefile ~/machinefile ./kNeighbor +ppn8 64 50
262144 10 +balancer TreeMatchLB +LBDebug 1 +setcpuaffinity +pemap 0-7
+CmiSleepOnIdle

The target platform contains 8 nodes with 8 cores on each. I would like
to carry out kNeighbor on 64 processes and parallelize only the load
balancing with CkLoop.

Do you have any suggestion?

Thanks

François
