Hi David, thanks for the detailed response. I am very new to using Paraview in parallel and still not very familiar with its terminologies. I want to make sure if I understood you correctly.
1. You are saying that I can install Paraview from source in my home directory on the remote machine? 2. If I want to use the cluster, installing Paraview from source on the remote (login) mode, such that the computer nodes can access it, should be sufficient? 3. If possible I would like to visualize a data of around 800 GB. A machine that I can use for visualization has the following specifications: *PRIMQUEST 1800E* *CPU：8CPU (XeonTM X7560 2.26GHz (8core))* *MEM：1TB* Do you have any intuitive ideas if this will be sufficient? 4. What is the oldest version of Python that Paraview is compatible with? Is this version fine? *Python 2.4.3 (#1, Apr 14 2011, 20:41:59) * *[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)]* * * I am sorry but I am very new to parallel visualization and I am having a bit of a tough time putting it all together :) Thanks Pradeep 2013/1/17 David E DeMarle <[email protected]> > On Thu, Jan 17, 2013 at 2:12 AM, Pradeep Jha > <[email protected]> wrote: > > Hello, > > > > I am trying to use PV for the first time in parallel.
