We have moved the cluster back to the department server room. All service has now resumed.
The Dynare installation on the cluster has been updated to version 5.4, which is the newest version available. The installation is only linked to MATLAB but not Octave. If you need Dynare with Octave, please contact support.
Since Microsoft is retiring Microsoft R Open (MRO) on June 30, 2023, we will retire the MRO installation on SCRP at the same time. As a replacement, we are offering a new Conda-based R installation that is linked to the Intel Math Kernel Library. Please refer to the guide on R for details.
June 2023 maintenance has completed, and all services have resumed. We regrettably report that due to software issues, the cluster has suffered data loss on the distributed storage.
Stata 18 is now available on cluster, and it will be the default version after the next maintainence in early June. In the meantime, you can access it through the terminal by typing the following commands:
Faculty members can now request the creation of group storage directories, which allow files to be shared among multiple users. Details here.
Two nodes crashed yesterday (Apr. 16) while running jobs dispatched by the same user. While we are still investigating the cause, we believe the most likely cause was the nodes running out of memory. As a precaution, we are reducing the amount of usable memory as follows:
Resource limit has been updated. Details here.
We are glad to announce that, with generous funding support from the department, SCRP now offers access to NVIDIA A100 datacenter GPUs. Blog post with benchmarks and instructions here.
We have replaced the detective components of
scrp-login. All services have resumed.
scrp-loginappears to have suffered a critical hardware failure and has gone offline.
- Please use
scrp-login-2.econ.cuhk.edu.hkfor the time being.
- Slurm and Jupyter (Slurm) jobs are unaffected by this outage.
/archiveis inaccessible because it is physically hosted on scrp-login.
- We should be able to replace any faulty hardware and bring the node back online on Monday (Nov. 14).
- Please use
You can now launch Jupyter—and by extension, the web GUI of MATLAB and R—on a compute node through the browser. This allows the interactive use of GPUs, more CPU cores and more memory on any device.
We will be conducting our annual account cleanup tomorrow at 10am. The following operations will be carried out:
The cluster’s SSL certificates got unexpectedly revoked before expiry this morning due to vendor change, resulting in the two login nodes becoming inaccessible. We have just obtained new certificates and all services have been restored.
Some users have reported that they have been unable to open existing MATLAB scripts in the MATLAB GUI since the last maintenance. It appears that the last MATLAB update has changed certain settings and if you delete your MATLAB settings, it will work again. Instructions below.
You can now switch input methods in remote desktop. Please follow the instructions here.
Summer 2022 maintenace has completed and the cluster is now line. List of changes below.
scrp-login has been rebooted and has regained outbound internet access. We have also taken this opportunity to implement the following changes:
R has been optimized to run certain linear algebra operations faster. Details here.
Xstata was launching noticably slower on
scrp-loginthan other nodes. This has been fixed.
You can now transfer files over remote desktop. Please follow the instructions under File Transfer.
