Power Outage Thursday 9th April to Monday 13th April
In preparation for the introduction of the new Cray supercomputer, there will be a site-wide power outage to the Data Centre currently housing Shaheen1 and Neser. All services, including Shaheen and Neser, will be shut down from 16:00 on Thursday 9th April until approximately 11:00 on Monday 13th April.
We apologise for the late notice and for any inconvenience that this may cause.
Introduction to Visualization Webcast Training
KAUST Supercomputing Lab (KSL) and KAUST Visualization Lab (KVL) are hosting on Friday 17th April 2015, a live webcast training in the library computer room from 5pm - 1am. In this one-day class, TACC Vis Staff will present information via webcast on available visualization resources. Training on the use of remote visualization software to visualize data sets generated on HPC systems will be provided. A review of the scientific visualization process and an overview of the visualization software available will also be provided.
A workshop is scheduled at the end of the day where in-person attendees who have brought their own laptops with Paraview 4.2.0 and/or Visit 2.8.1 installed, will be able to work on their own data with KSL/KVL staff assistance. Paraview and Visit are available via the KAUST IT Managed Software Center software.
Please complete the survey at http://tiny.cc/ksl_kvl_vis15/ in order to register.

Tip of the Week: Find Command
It is very common to use the
find command to search for files from command line on Linux/Unix systems. Find will search any set of directories you specify for files that match the supplied search criteria. You can search files by name, owner, group, type, permissions, date and other criteria. The syntax is:
find where-to-look criteria what-to-do
To search all pathname for all files in the current directory and all subdirectories:
To search for any files named foo and display their pathnames in the user's directory:
find $HOME -name foo
If find doesn’t locate any matching files, it produces no output.
You can specify as many places to search as you wish:
find /tmp /var/tmp . $HOME -name foo
More features can be found by typing
man find and visiting this link http://www.binarytides.com/linux-find-command-examples/

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).
