Tip of the Week: Running multiple single jobs on one node
The script provided below is primarily for running multiple serial jobs on one node. Note that this method can have undesirable effects when attempting to run jobs on more than one node. Don't forget the wait command at the end of the script, it's an essential command for multiple individual jobs. wait is a command which pauses until execution of a background process has ended.
#!/bin/sh #@ job_name = multi1 #@ environment = COPY_ALL; #@ job_type = parallel #@ wall_clock_limit = 0:10:00 #@ account_no = <<<<your account>>>> #@ node = 1 #@ total_tasks = 8 #@ node_usage = not_shared #@ queue cd case1 ./a.exe & cd .. cd case2 ./a.exe & cd .. cd case3 ./a.exe & cd .. cd case4 ./a.exe & cd .. cd case5 ./a.exe & cd .. cd case6 ./a.exe & cd .. cd case7 ./a.exe & cd .. cd case8 ./a.exe & cd .. wait

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).
