Application License Server Maintenance by IT on Thursday, 26th November 2020, 8.00 PM to 4:00 AM 27th November
Due to a scheduled maintenance of the Application License Server by IT on Thursday, 26th November 2020, 8.00 PM to 4:00 AM next day, access to the below applications will be impacted on Shaheen and Neser:
Ansys, AtomistixToolKit (ATK), Converge, Eclipse, Intel Compilers, Material Studio, Mathematica, MATLAB, Tecplot and Totalview.
During these maintenance windows, you may face issues with Intel at compilation and error with the application at runtime.
The system will be unavailable between 01.12.2020 1pm and 03.12.2020 5pm. During this outage, we will perform essential datacentre modification in preparation for the new filesystem. We will also upgrade and patch Shaheen to the latest software levels.
Please note that access to files will not be possible during this time. Also, persistent burst buffer allocations will be cleared.
Please get in touch with us at firstname.lastname@example.org should this cause any issues for your projects.
7th KAUST-NVIDIA Workshop on Accelerating Scientific Applications using GPUs Session
The KAUST Supercomputing Core Laboratory (KSL) in collaboration with NVIDIA are pleased to invite you to the 7th annual workshop on "Accelerating Scientific Applications using GPUs". This event provides an opportunity for attendees to learn about the latest advances by NVIDIA in Scientific Computing and Artificial Intelligence as well as showcasing the related KAUST success stories using GPUs.
The event includes also hackathon and AI competition.
Registration and more information are available here: https://www.hpc.kaust.edu.sa/GPU-2020
Seminar on Overview on HPC Numerical Libraries & Success Stories
The KAUST Supercomputing Core Laboratory (KSL) invites you to the next session of the KSL seminar series entitled: “Overview on HPC Numerical Libraries & Success Stories”. The seminar will take place on Monday, December 7th 2020, 3 pm - 5 pm via Zoom.
The goal of this seminar is to bring awareness of optimized numerical libraries installed on KAUST High Performance Computing (HPC) resources. The idea is to get an overview on the state-of-the-art numerical packages and to demonstrate how their integrations into real applications (e.g., Astronomy, Climate and CFD applications ) may further leverage the overall performance.

Tip of the week: Exclusive option for job step
On Shaheen, the nodes are by default exclusive, the job allocation cannot share nodes with other running jobs from other users. This option is in general used for the node allocation.
This option can also be used when initiating more than one job step within an existing resource allocation, where you want separate processors to be dedicated to each job step in order to get adequate performance. If sufficient processors are not available to initiate the job step, it will be deferred. This can be thought of as providing a mechanism for resource management to the job within its allocation.
All cores allocated to a job are available to each job step in the node unless the --exclusive option is used plus task affinity is configured along with --ntasks option must be specified. A reminder, the & and wait must be specified too. Here is an example:
srun --hint=nomultithread --ntasks=4 --exclusive ./exe_mycode & srun --hint=nomultithread --ntasks=4 --exclusive ./exe_mycode & srun --hint=nomultithread --ntasks=4 --exclusive ./exe_mycode & wait
