If you haven't heard, we recently launched an on-campus S3-compatible object storage service called Kopah [docs] that is available to the research community at the University of Washington. Kopah is built on top of Ceph and is designed to be a low-cost, high-performance storage solution for data-intensive research.

While the deployment of Kopah was welcome news to those who are comfortable working with S3-compatible cloud solutions, we recognize some folks may be hesitant to give up their familiarity with POSIX file systems. If that sounds like you, we explored the use of JuiceFS, a distributed file system that provides a POSIX interface on top of object storage, as a potential solution.

Installation​

JuiceFS isn't installed by default so you will need to compile it yourself or download the pre-compiled binary from their release page.

As of January 2025 the latest version is 1.2.3 and you want the amd64 version if using from Klone. The command below will download and extract the binary to your current working directory.

wget https://github.com/juicedata/juicefs/releases/download/v1.2.3/juicefs-1.2.3-linux-amd64.tar.gz -O - | tar xzvf -

I have to move it to a folder in my $PATH so I can run it from anywhere by just calling the binary. Your personal environment varies here.

mv -v juicefs ~/bin/

Verify you can run JuiceFS.

npho@klone-login03:~ $ juicefs --version
juicefs version 1.2.3+2025-01-22.4f2aba8
npho@klone-login03:~ $ 

Cool, now we can start using JuiceFS!

Standalone Mode​

There are two ways to run JuiceFS, standalone or distributed mode. This blog post explores the former. Standalone mode is meant to only present Kopah via POSIX on Klone. The key points being:

1. There is an active juicefs process required to run while you want to access it.
2. It is intended for you to run it only on the node you are running the process from.

If you wanted to run JuiceFS on multiple nodes or with multiple users then we will have another proof-of-concept with distributed mode in the future.

Create Filesystem​

JuiceFS separates the data (placed into S3 object storage) and the metadata, which is kept locally in a database. The command below will create the myjfs filesystem and store the metadata in a SQLite database called myjfs.db in the directory where the command is run. It puts the data itself into a Kopah bucket called npho-project.

juicefs format \
  --storage s3 \
  --bucket https://s3.kopah.uw.edu/npho-project \
  --access-key REDACTED \
  --secret-key REDACTED \
  sqlite3://myjfs.db myjfs

You can rename the metadata file and the filesystem name to whatever you want (they don't have to match). The same goes for the bucket name on Kopah. However, I would strongly recommend having unique metadata file names that match the file system names for ease of tracking alongside the bucket name itself.

npho@klone-login03:~ $ juicefs format \
>   --storage s3 \
>   --bucket https://s3.kopah.uw.edu/npho-project \
>   --access-key REDACTED \
>   --secret-key REDACTED \
>   sqlite3://myjfs.db myjfs

  "EnableACL": false
} [format.go:521]
npho@klone-login03:~ $ 

You can verify there is now a myjfs.db file in your current working directory. It's a SQLite database file that will store your file system meta data.

We can also verify the npho-project bucket was created on Kopah to store the data itself.

npho@klone-login03:~ $ s3cmd -c ~/.s3cfg-default ls                                      
2025-01-31 19:48  s3://npho-project
npho@klone-login03:~ $ 

You should run juicefs format --help to view the full range of options and customize the parameters of your file system to your unique needs but just briefly:

• Encryption: When you create the file system and format it you can see it has encryption by default using AES256. You can over ride this using the --encrypt-algo flag if you prefer chacha20-rsa or you can use key file based encryption and provide your private key using the --encrypt-rsa-key flag.
• Compression: This is not enabled by default and there is a computational penalty for doing so if you want to access your files since it needs to be de or re encrypted on the fly.
• Quota: By default there is no block (set with --capacity in GiB units) or inode (set with --inodes files) quota enforced at the file system level. If you do not explicitly set this, it will be matched to whatever you get from Kopah. This is still useful for setting explicitly if you wanted to have multiple projects or file systems in JuiceFS that use the same Kopah account and have some level of separation.
• Trash: By default, files are not deleted immediately but moved to a trash folder similar to most desktop systems. This is set with the --trash-days flag and you can set it to 0 if you want files to be deleted immediately. The default here is 1 day after which the file is permanently deleted.

Mount Filesystem​

Running the command below will mount your newly created file system to the myproject folder in your home directory. It does not need to previously exist.

juicefs mount sqlite3://myjfs.db ~/myproject --background

This process occurs in the background.

npho@klone-login03:~ $ juicefs mount sqlite3://myjfs.db ~/myproject --background
2025/01/31 11:57:01.652279 juicefs[1690855] <INFO>: Meta address: sqlite3://myjfs.db [interface.go:504]
2025/01/31 11:57:01.654920 juicefs[1690855] <INFO>: Data use s3://npho-project/myjfs/ [mount.go:629]
2025/01/31 11:57:02.156898 juicefs[1690855] <INFO>: OK, myjfs is ready at /mmfs1/home/npho/myproject [mount_unix.go:200]
npho@klone-login03:~ $ 

Use Filesystem​

Now with the file system mounted (at ~/myproject) you can use it like any other POSIX file system.

npho@klone-login03:~ $ cp -v LICENSE myproject 
'LICENSE' -> 'myproject/LICENSE'
npho@klone-login03:~ $ ls myproject 
LICENSE
npho@klone-login03:~ $ 

Remember, you won't be able to see it in the bucket because it is encrypted before being stored there.

Recover Deleted Files​

If you enabled the trash can option then you can recover files up until the permanent delete date.

First delete a file on the file system.

npho@klone-login03:~ $ cd myproject 
npho@klone-login03:myproject $ rm -v LICENSE 
removed 'LICENSE'
npho@klone-login03:myproject $

Verify the file is deleted. Go to recover it from the trash bin.

npho@klone-login03:myproject $ ls          
npho@klone-login03:myproject $ ls -alh          
total 23K
drwxrwxrwx  2 root root 4.0K Jan 31 12:54 .
drwx------ 48 npho all  8.0K Jan 31 13:08 ..
-r--------  1 npho all     0 Jan 31 11:57 .accesslog
-r--------  1 npho all  2.6K Jan 31 11:57 .config
-r--r--r--  1 npho all     0 Jan 31 11:57 .stats
dr-xr-xr-x  2 root root    0 Jan 31 11:57 .trash
npho@klone-login03:myproject $ ls .trash  
2025-01-31-20
npho@klone-login03:myproject $ ls .trash/2025-01-31-20 
1-2-LICENSE
npho@klone-login03:myproject $ cp -v .trash/2025-01-31-20/1-2-LICENSE LICENSE
'.trash/2025-01-31-20/1-2-LICENSE' -> 'LICENSE'
npho@klone-login03:myproject $ ls                     
LICENSE
npho@klone-login03:myproject $ 

As you can see, we can recover files that are tracked by their delete date. You would need to copy the file back out to recover it.

Unmount Filesystem​

When you are done using the file system you can unmount it with the command below.

npho@klone-login03:~ $ juicefs umount myproject
npho@klone-login03:~ $ 

Remember, the file system is only accessible in standalone mode so long as a juicefs process is running. Since we ran it in the background you will need to explicitly unmount it.

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:
