Maintenance Session Tuesday 18th August
The next maintenance session will be on Tuesday 18th August from 12:00 until 17:00. There will be no access to the system during this period. This will affect Shaheen I, Neser and Shaheen II. Important security updates, custom patches and several bug fixes will be applied to the XC40, which will require the whole system to be rebooted.
Tip of the Week: What command did I type before ?
The “history” command will output the recently-executed commands recorded in a history list. More details about available in the man pages
Searching through the Command History ( CTRL+R )
Use the CTRL+R keys to perform a “reverse-i-search”. For example, if you wanted to use the command you used the last time you used grep, you would type:
CTRL-R then type “grep”.
What you will see in the console window is:
After you have typed what you are looking for, use the CTRL-R key combination to scroll backward through the history.
Use CTRL+R repeatedly to find every reference to the string you've entered. Once you've found the command you're looking for, use [Enter] to execute it. Alternatively, using the right or left arrow keys will place the command on an actual command-line so you can edit it.

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:
Shaheen I: Project Proposal
Shaheen II: Project Proposal
- 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).
