New Tools Documentation​

Our research computing interns have been hard at work adding documentation for new user tools that might help optimize your research computing. Click the links below to review the docs for these tools.

Squash Fuse - SquashFS packages multiple small files into a single read-only, compressed filesystem, reducing metadata calls and improving performance. This minimizes server load, enhancing throughput and efficiency in handling storage requests.

Use case on Hyak: In HPC, datasets often consist of numerous small files, which can lead to performance bottlenecks due to excessive metadata operations. By utilizing SquashFS, HPC applications can significantly reduce metadata overhead, improving data access speeds and enhancing overall system performance, particularly in large-scale distributed storage systems.

Checkpointing with DMTCP - DMTCP is a tool to transparently checkpoint and restart jobs, saving it to disk to be resumed at a later time. It requires no changes to application code, allowing easy use. Using DMTCP with your code allows checkpointing at regular intervals so if your job is pre-empted or reaches the time limit, it will resume from its last checkpoint.

Use case on Hyak: DMTCP offers a solution for folks who would like to use Hyak's ckpt partitions, but have jobs that exceed the ckpt time limits of 5 hours for CPU-noly jobs and 8 hours for GPU-only jobs. Checkpointing with DMTCP facilitates efficient use of ckpt resources, allowing higher throughput for your jobs.

Tools for Kopah Storage Users - We have installed Command Line Interface tools like s3cmd and s5cmd on klone and provide insctructions for using Python library boto3 for Kopah interaction and retreival to build Kopah S3 storage usage into your research computing applciations on Hyak.

If you have any issue using these tools, please open a ticket by emailing help@uw.edu with "Hyak" in the subject line. We appreciate any feedback about how to improve ease of use for tools presented in our documentation.

Thanks again for your patience with our monthly scheduled maintenance. During this maintenance session, we were able to provide package updates to node images to ensure compliance with the latest operating system level security fixes and performance optimizations. Of note, the Nvidia GPU driver on Klone has been updated to the latest production datacenter release, version 560.35.03.

The next maintenance will be Tuesday October 8, 2024.

AMD Math libraries​

In June we announced the addition of AMD Nodes and Slices to klone which make up our generation 2 or g2 collection of resources. Click here to read more about the difference between our g1 and g2 resources. During August, we installed a new AMD compiler suite, AOCC, along with specialized math libraries like AOCL, OpenBLAS, and ScaLAPACK as modules to make the most of this upgade. The new modules are useful on all partitions. The AOCC and AOCL modules are particularly relevant for partitions cpu-g2, cpu-g2-mem2x, and ckpt-g2. These tools are designed to optimize performance on AMD processors, speeding up complex mathematical computations. Whether you're working on simulations, data analysis, or any number-crunching tasks, these libraries may help ensure you get faster, more efficient results. If you're looking to boost your workflow, it's worth exploring how these libraries can benefit your projects. Here are the names of the new modules:

aocc/4.2.0
aocl/4.2.0
openblas/0.3.28
scalapack/2.2.0

In our benchmarking tests, performance of these libraries was similar on g1 and g2 CPUs for each math library, regardless of architecture. The best library performer on AMD CPUs is AOCC+AOCL, and for Intel CPUs it’s OpenBLAS+ScaLAPACK:

New self-hosted S3 storage option: KOPAH​

We are happy to announce the preview launch of our self-hosted S3 storage called KOPAH. S3 storage is a solution for securely storing and managing large amounts of data, whether for personal use or research computing. It works like an online storage locker where you store can files of any size, accessible from anywhere with an internet connection. For researchers and those involved in data-driven studies, it provides a reliable and scalable platform to store, access, and analyze large datasets, supporting high-performance computing tasks and complex workflows.

S3 uses buckets as containers to store data, where each bucket can hold 100,000,000 objects, which are the actual files or data you store. Each object within a bucket is identified by a unique key, making it easy to organize and retrieve your data efficiently. Public links can be generated for KOPAH objects so that users can share buckets and objects with collaborators.

Click here to learn more about KOPAH S3.

Who should use KOPAH?​

KOPAH is a storage solution for anyone. Just like other storage options out there, you can upload, download, and view your storage bucket with specialized tools and share your data via the internet. For Hyak users, KOPAH provides another storage option for research computing. It is more affordable than /gscratch storage and can be used for active research computing with a few added steps for retreiving stored data prior to a job.

Test Users Wanted​

Prior to September, we are inviting test users to try KOPAH and provide feedback about their experience. If you are interested in becoming a KOPAH test user, please each help@uw.edu with Hyak or KOPAH in the subject line.

Requirements:

1. While we will not charge for the service until September 1, to sign up as a test user, we require a budget number and worktag. If the service doesn't work for you, you can cancel before September.
2. We will ask for a name for the account. If your groups has an existing account on Hyak, klone /gscratch, it makes sense of the names to match across services.
3. Please be ready to respond with your feedback about the service.

Opportunities​

PhD students should check out this opportunity for funding from NVIDIA: Graduate Research Fellowship Program

Questions? If you have any questions for us, please reach out to the team by emailing help@uw.edu with Hyak in the subject line.

Thanks again for your patience with our monthly scheduled maintenance. This month, we deployed new node resources that were purchased by various UW Researchers from across campus. These nodes are a little different, so we wanted to bring your attention to them and provide guidance on their use when they are idle with the checkpoint partition.

New G2 Nodes​

A new class of nodes have been deployed on klone which we are calling g2 because they are the second generation of nodes, and we will retroactively refer to the first generation nodes as g1. g2 CPU nodes feature AMD EPYC 9000-series 'Genoa' processors, and new GPU nodes featuring either NVIDIA L40 or L40S GPUs (with H100 GPUs possibly becoming available in the future). These nodes will join our community resources that can be used when idle (ckpt) under the new partitions:

• ckpt-g2 for scheduling jobs on g2 nodes only.
• ckpt-all for scheduling jobs on either g1 or g2 nodes.
• ckpt will now schedule jobs on g1 nodes only.

Please review our documentation HERE for specific instructions for accessing these resources. Additionally, please see the blog post HERE where we discuss additional considerations for their usage.

To accompany the new g2 node deployments, we are providing a new Open MPI module (ompi/4.1.6-2), which is now the default module when module load ompi is executed. Previous OpenMPI modules will cause errors if used with the AMD processors on the new g2 nodes due to how the software was compiled. ompi/4.1.6-2 (and any openmpi module versions we provide in the future) are compiled to support both Intel and AMD processors. If your MPI jobs are submitted to a partition that includes g2 nodes, you should use module load ompi to use the new module by default, or explicitly load ompi/4.1.6-2 (or a newer version in the future) via module load ompi/4.1.6-2.

If you have compiled software on g1 nodes, you should test them on g2 nodes before bulk submitting jobs to partitions with g2 nodes (i.e., ckpt-g2 and ckpt-all), as they may or may not function properly depending on exactly how they were compiled.

Hello Hyak Community,

Thanks again for your patience with our monthly scheduled maintenance, there are some notable improvements we implemented today.

klone node image: Over the past few weeks, you may have noticed some klone instability. This was a result of some behind the scenes storage upgrades that inadvertently introduced wider impacts to the existing cluster automation. At the time, we introduced a temporary fix to get the cluster back online but with today’s maintenance we implemented a more comprehensive fix.

Infiniband firmware: The klone cluster is built on the infiniband HPC interconnect for node-to-node communication. While klone originally launched with the HDR generation of infiniband, we have since upgraded mid-klone to have a HDR-NDR hybrid interconnect. NDR infiniband is required to support the latest compute slices we offer. We updated the firmware on our NDR switches following vendor recommendations for increased stability.

Apptainer on MOX: Apptainer (formerly Singularity) is the root-less containerization solution we provide on both Hyak clusters. Apptainer version 1.3.1 was deployed on both klone and MOX. As a reminder, on klone Apptainer is accessed through a module and is only available on compute nodes after module load apptainer. On MOX, Apptainer is default software and can be accessed with Apptainer commands directly after starting an interactive job for example, apptainer --version.

Training Opportunities: COMPLECS (San Diego Supercomputer) is hosting an Intermediate Linux Shell Scripting online workshop on Thursday May, 16 at 11:00 am Pacific Time. Register here.

Our next scheduled maintenance will be Tuesday June, 11, 2024. Stay informed by joining our mailing list. Sign up here.

Questions? If you have any questions for us, please reach out to the team by emailing help@uw.edu with Hyak in the subject line.

Thank you for your patience this month while there was more scheduled downtime than usual to allow for electrical reconfiguration work in the UW Tower data center. We appreciate how disruptive this work has been in recent weeks. Please keep in mind that this work by the data center team has been critical in allowing the facility to increase available power to the cluster to provide future growth capacity, which was limiting deployment of new equipment in recent months.

The Hyak team was able to use the interruption to implement the following changes:

• Increase in checkpoint (--partition=ckpt) runtime for GPU jobs from 4-5 hours to 8-9 hours (pre-emption for requeuing will still occur subject to cluster utilization). Please see the updated documentation page for information about using idle resources.
• The NVIDIA driver has been updated for all GPUs.

Our next scheduled maintenance will be Tuesday May 14, 2024.
