Tip of the Week: Using ParaView on Neser
ParaView is a scalable and distributed visualization built on VTK by Kitware. It is used primarily to visualize large or complex data-sets with the aid of a cluster. This can then be seen and explored through the use of a connected client machine. You need to have ParaView installed on the local client machine. The latest version for Mac/Windows/Linux - can be downloaded from http://www.paraview.org/paraview/resources/software.php. Make sure that the version you install is consistent with the version on the cluster. Information about the usage can be found at http://www.hpc.kaust.edu.sa/software/paraview/.
The following steps illustrate the full process:
1) Log into Neser, and submit a loadleveler job that starts pvserver. This is an example script that you might use (job_script.sh).
#!/bin/sh # @ job_name = paraview # @ job_type = parallel # @ wall_clock_limit = 1:00:00 # @ node = 2 # @ tasks_per_node = 8 # @ account_no = <account> # @ queue # Load environment modules source /etc/profile.d/modules.sh module load paraview # Define the address of your ParaView client workstation client=<workstation ip address> # Run pvserver with OpenMPI $MPIEXEC -x LD_LIBRARY_PATH -np $LOADL_TOTAL_TASKS \ $(which pvserver) --reverse-connection --client-host=$client
2) Launch ParaView on the client machine, and click “Connect”
3) You will then be prompted with a dialog box – click “Add Server” to create a new saved connection.
4) Give the connection a memorable name and select “Client/Server (reverse connection)” as the Server Type.
5) After you configure, select “Manual” as the Startup Type and save this new connection.
6) Once this is saved select it and connect.

Questions, concerns, or problems related to Shaheen should be directed to email@example.com. From there your issue will be assigned to an appropriate primary contact who will track your issue to resolution. We may sometimes have to request items from KAUST IT or other service providers.
Getting an account
FAQs on the process and requirements for obtaining access to the Shaheen Systems are available here.
Getting an account on Shaheen is a three-step process and is detailed in this flowchart.
You should consult our Terms and Conditions of Usage.
- Your organisation or department must submit the Organisational Access Application, establishing a relationship between your home organisation and the KAUST Supercomputing Laboratory (KSL).
- You (or your Principal Investigator) must submit a Project Proposal describing the work to be done and the resources your project will require.
- You must submit an Individual Account Application, supplying identification information from which we can generate login credentials.
Use the secure submission form to submit credentials or other private information.
Accessing KSL Systems
After you have been given login credentials (i.e., a username and password) you will be able to access any Shaheen systems to which you have been granted access. Primary computational access to Shaheen and Neser is available via the ssh (secure shell) protocol:
PIs are required to submit periodic project reports during the course of their work on the KSL systems, there is a template available for this.
Data Centre Visits
To request a visit to the Data Centre, in the first instance, please complete this form.
Because the Shaheen Systems are a widely shared resource, user reservations are not encouraged. However, if a user feels that making a reservation for dedicated access to all or part of the Shaheen systems is essential for their work, then KSL will consider such requests on a case-by-case basis within the bounds of the following guidelines:
- A minimum of 14 days, preferably 30 days, notice is required for all reservations.
- The maximum duration allowed for a reservation will be 48 hours.
- A reservation may request dedicated access to between 1 and 16 racks of the Shaheen BG/P system. Reservations of less than 1 rack of BG/P will not be permitted.
- Users’ project accounts will be charged for all racks reserved for the entire reservation period, regardless of whether they are all used or not.
- There are no guarantees that a reservation request will be accepted.
Exceptions to this policy may be allowed based on the merits of a request, but very rarely.
- If a user has a complaint about a KSL decision relating to resource allocation, and the user remains unhappy after discussing their concerns with KSL Management, users can request arbitration from the Chairman of the KSL Resource Allocation Committee (KSL RAC) (currently Dr David Keyes). If the user remains unhappy with the decision of the Chairman of the KSL RAC, users can request arbitration from the Chairman of the KSL Management Committee (KSLMC).
- If a user has a complaint about KSL policies, or other matters not relating to resource allocation, and the user remains unhappy after discussing their concerns with KSL Management, users can request arbitration from the Chairman of the KSL Management Committee (KSLMC).
