The transition to our new domain is complete. All machines are now referred to as cfarmXX, or The old naming convention and domain (gccXX and are obsolete and should not be used.

The website formerly at is now available (with redirects) at, and a new landing page for the project, complete with documentation, will soon be available directly at This is still in progress.

DNS records for will no longer be updated, and new machines will only be added under the domain.

The Compile Farm project is pleased to announce the immediate availability of cfarm240, an Arm Morello SoC prototype board running CheriBSD (a FreeBSD derivative).

This system-on-chip research platform features a custom quad-core aarch64 Neoverse N1-based CPU implementing CHERI (a memory protection model), and has 32GB system memory. Disk space is limited (~200GB); please be mindful of your resource usage.

We are still in the process of transitioning to our new domain name and website; please SSH to


  • Morello boards are the only physical implementation of this ISA; lessons learned will be carried to future Arm extensions, so binary compatibility with Morello is not guaranteed.
  • You will want to read about packages.
  • If you need help with CHERI-specific problems (not Compile Farm issues), consider joining their Slack.

Thank you to the University of Cambridge for hosting (and developing) this machine!

The Compile Farm project is happy to announce two new sparc64 LDOMs, each with 32 dedicated threads, 32GB memory, and 1.5TB of disk. They are hosted on a SPARC T4-2 server.

One runs Debian on Linux 6.3, and the other runs Oracle Solaris 11.4.

The Linux system, cfarm105, replaces gcc102 (a SPARC T3-2* that suffered from irreparable hardware problems and is being removed from its data center today). All user accounts and data have been migrated.

The Solaris system, cfarm106, is the Farm's first Solaris 11.4 machine and we hope it will prove interesting and useful. It has been set up with a substantial number of Oracle-provided developer tools, including Rust 1.61, LLVM 14, and GCC 12. The OpenCSW package manager has been installed as well.

We are in the process of transitioning to our own domain name,, online now at:

  • ssh -p 2202 (Linux)
  • ssh -p 2203 (Solaris)

An announcement with details about our new domain, website, and other project-related matters will be made soon. Please consider switching to from for all machines as soon as possible. The "old" subdomains will continue to work but may not be updated.

These sparc64 systems are donated, hosted, and managed by Adélie Linux.
Thanks to for hosting gcc102 for the last 3 years.

* Compared to the T3 (in-order execution), the T4 (out-of-order) has much better single-threaded performance.

POWER10 machine


We now have a POWER10 machine in the Compile Farm: gcc120.

It is donated by IBM, and hosted at OSUOSL like most Power machines.  Thanks!

It is an IBM E1050, 192 hardware threads, 2TB RAM, 11TB disk.  It runs AlmaLinux, a RHEL descendant / clone.

It is open for general use immediately.  Enjoy, but use it responsibly: most importantly, always be aware other people want to use it as well :-)

GCC bootstrap takes 26m, and testsuite takes 6m.  With --enable-languages=all.  But Ada and D did not actually build, I'll work on getting some working pre-built compilers for those installed in /opt/cfarm for that, which you can use to build new compilers with.

Thanks to everyone involved for making this reality at long last!

Software in the Public Interest (SPI) is a 501(c)(3) non-profit corporation registered in the state of New York founded to act as a fiscal sponsor for organizations that develop open source software and hardware.

Compile Farm has been accepted as an SPI Associated Project.

This does not bind Compile Farm to SPI in any way. It means that SPI will accept donations, hold assets, and provide legal assistance on our behalf. SPI can also sign contracts for us.

Fundraising is an important function of any major project, and having the ability to do so transparently and legitimately means we can more easily acquire new hardware, repair existing hardware, and hire contractors should the need arise.

We're looking into similar arrangements with European charities.

We have a new Apple M1 machine running macOS, gcc104. It should provide the same kind of services as gcc304 (which is no longer available). Disk space is limited, so please be mindful and clean up your working trees when you no longer need them.

Many additional software are installed through homebrew. However, they are not enabled by default because they may conflict with native macOS tools. To use them, either run the custom homebrew command to update your $PATH, or use binaries directly from /opt/homebrew/bin/.

Many thanks to Adélie Linux for providing and hosting this new machine!

gcc13 and gcc14 will be replaced with new hardware on October 9th. Starting from this date, the DNS names for gcc13 and gcc14 will be changed to point to the new machines.

Data will not be copied over to the new machines. Please backup any important data you have on the old machines.

gcc14 will remain available for a limited amount of time after the change, and will still be reachable under its IP address (

gcc13 experienced a disk failure some time ago and is not currently reachable, but some of its data was copied to gcc14 under /home/gcc13/. It was unfortunately not possible to recover all data from gcc13.

Thanks a lot to Smile for hosting these machines for many years and for their continuing support!

Due to frequent hardware failures and the resulting support load on our hosting provider, the shared OpenCompute machines will be definitely shut down in one month (1st of July 2022). This applies to gcc120, gcc121, gcc122, gcc123, and gcc140.

OSUOSL has kindly provided new machines to replace them:

  • gcc186 running Debian 11.3
  • gcc187 running CentOS 8 Stream
  • gcc188 running openSUSE Leap 15.4

Everybody should migrate to these new machines as soon as possible. Any user data left on the old machines will be definitely lost when the machines are shut down.

For the experimental RISC-V virtual hosts on gcc140, we hope to find a replacement solution very soon.

As always, a big thanks to OSUOSL for their excellent support!

We are very excited to announce the availability of an Apple M1 machine running Linux natively! It is accessible over SSH to all current and future compile farm users at
To our knowledge, this is the first publicly-accessible Linux host running on the M1 chip. We hope it will lead to interesting results. For example, it is now possible to do performance comparisons with other aarch64 hosts (gcc80, gcc185) or with our existing Apple M1 machine running macOS (gcc304). When performing benchmarks, please keep in mind that the machine is shared with many users: results may vary depending on the current load. The new machine should also help in improving free software support for the peculiar M1 chipset, especially its heterogeneous core architecture.
The CPU has 8 heterogeneous cores: 4 "efficiency" cores running at up to 2 GHz, and 4 "performance" cores running at up to 3.2 GHz. All cores can be used at the same time. This is similar to the big.LITTLE architecture from ARM. Don't be fooled by the 8GB of memory available on the machine: compiling GCC with all 8 cores is incredibly fast and peaks at less than 1.5GB of total memory usage.
Providing this machine publicly is only possible thanks to the hard work of the Asahi Linux project: they have been working for months on porting the Linux kernel to the new M1 chipset, with a focus on upstreaming the result of this work. We are running their kernel:
Linux 5.17.0-rc6-asahi-next-20220301-25570-gc09fe28af1d3 #1 SMP PREEMPT Thu Mar 10 09:33:48 CET 2022 aarch64 GNU/Linux
The userspace is a standard aarch64 Debian bookworm distribution.
Many thanks to Jeffrey Walton for donating the hardware, to Zach van Rijn for figuring out how to setup everything, to Thomas Glanzmann for his help with Debian support, to Adélie Linux for hosting it, and again to Asahi Linux for the hard work making this possible!
We are always looking for more hardware donations. In the case of M1 machines, that would allow us to provide more OS variants (Arch Linux, 4K pages...) and different hardware (M1 pro, M1 max...). If you have hardware to spare, feel free to contact us!
PS: For those interested in the full details, Zach has written up a complete installation walkthrough here:
EDIT 2022-03-13: the machine is now running with a kernel configured for 16 KB page size, while it was 4 KB before. This should improve performance, but can also trigger interesting bugs in some software.

We are happy to announce the availability of two Loongson machines with a recent LoongArch 3A5000 processor running at 2.5 GHz: gcc400 and gcc401.

As a starting point, the machines run a custom Cross-LinuxFromScratch (CLFS) build and the software environment is somewhat experimental. Feel free to report any issues or missing software, either directly or through the cfarm-users mailing list to discuss it with other users. As a known issue, some websites such as Github may not be reachable due to local network restrictions.

As usual, make sure to use the correct SSH port, as listed in the list of machines. We also provide a ready-to-use SSH client configuration, just click Show ssh config at the top of the page.

The machines are hosted in Beijing, China by Loongson Technology, thanks to them!
