</div>You shouldn't need root permissions. You can build paraview in your<br>
home directory (or anywhere that the remote machine can read from) and<br>
connect to that. You generally don't even have to run make install.<br>

<br>
</div>Our binaries typically don't have an MPI in them that will work on the<br>
cluster's network. What we have is more or less just for making use of<br>
the cores on a single node. So you typically have to compile paraview<br>
on the cluster and enable MPI to use it in distributed memory parallel<br>
settings. It should work for you on the remote node, but not the<br>
cluster.<br>

</div>This is most often happens when the client and server are mismatching<br>
versions (3.14 connecting to 3.10 etc), but various network problems<br>
can result in the same thing.<br>

Same comment as before, you only have to have a paraview built<br>
somewhere that the compute nodes can access, so you shouldn't have to<br>
install it.<br>
<br>

><br>
<br>
A word of caution - more nodes does not necessarily mean faster.<br>
ParaView's parallel architecture allows it to process larger data and<br>
larger data as more disks and memory are added - not the same sized<br>
data faster and faster using more CPUs and GPUs are added (accept in<br>
the infrequent case when processing and rendering are the<br>
bottlenecks).<br>
<div class="im"><br>

<br>
</div>You'll need to set up an ssh tunnel through the remote (login) node to<br>
the cluster in your job submission to do that.<br>
