Well, I can reproduce it - but I won’t have time to address it until I return
later this week.
Whether or not procs get spawned onto a remote host depends on the number of
local slots. You asked for 8 processes, so if there are more than 8 slots on
the node, then it will launch them all on the
Yeah, I don’t think that the slurm bindings will work for you. Problem is that
the slurm directive gets applied to the launch of our daemon, not the
application procs. So what you’ve done is bind our daemon to 3 cpus. This has
nothing to do with the OMPI-Slurm integration - you told slurm to bin
Dave,
the QDR Infiniband uses the openib btl (by default :
btl_openib_exclusivity=1024)
i assume the RoCE 10Gbps card is using the tcp btl (by default :
btl_tcp_exclusivity=100)
that means that by default, when both openib and tcp btl could be used,
the tcp btl is discarded.
could you give a try
I have pushed the changes to the OMPI master. It took a little bit more than I
had hoped due to the changes to the ORTE infrastructure, but hopefully this
will meet your needs. It consists of two new tools:
(a) orte-dvm - starts the virtual machine by launching a daemon on every node

Because the compiler does not know that you want to send the entire
sub-matrix, passing non-contiguous arrays to a function is, at best,
dangerous, do not do that unless you know the function can handle that.
Do AA(1,1,2) and then it works. (in principle you then pass the starting
memory location a
Hi,
I created an issue with a simplified example:

Hi,
I also reproduce this behaviour. But I think this crash is not related
with garbage collector. Java is much better than you
