Reference Hardware Specs

The transaction weights in Cere are benchmarked on reference hardware.

• CPU

  • x86-64 compatible;
  • Intel Ice Lake, or newer (Xeon or Core series); AMD Zen3, or newer (EPYC or Ryzen);
  • 4 physical cores @ 3.4GHz;
  • Simultaneous multithreading disabled (Hyper-Threading on Intel, SMT on AMD);
  • Prefer single-threaded performance over higher cores count. A comparison of single-threaded performance can be found here.

• Storage

  • An NVMe SSD of 1TB

    In general, the latency is more important than the throughput.

• Memory

  • 32 GB DDR4 ECC.

• System

  • Linux Kernel 5.16 or newer.

• Network

  • The minimum symmetric networking speed is set to 500 Mbit/s (= 62.5 MB/s).

The specs posted above are not a hard requirement to run a validator, but are considered best practice. Running a validator is a responsible task; using professional hardware is a must in any way.

Enable Landlock (Linux Only)

Landlock is a Linux security feature used in Cere, and should be enabled.

Landlock empowers any process, including unprivileged ones, to securely restrict themselves.

To make use of landlock, make sure you are on the reference kernel version or newer. Most Linux distributions should already have landlock enabled, but you can check by running the following as root:

dmesg | grep landlock || journalctl -kg landlock

If it is not enabled, please see the official docs ("Kernel support") if you would like to build Linux with landlock enabled.
