Manticore Mac OS
Manticore Mac OS
Manticore currently only supports the x86-64 (a.k.a. AMD64) architecture running on either Linux or Mac OS X. Manticore is implemented in a mix of C and SML code. You will need a recent version of SML/NJ (version 110.81) installed. Furthermore, your installation should include the MLRISC library.
- Manticore provides scripts to combine all the source JavaScript code (and its dependencies) into one large file, using (among other things) browserify and folderify. This is the implementation code, for which the native shims are the interface. For more information, see the README in lib/mantify. Initialization: Launching Manticore-Powered Code.
- General building options¶. For compiling latest version of Manticore, recommended is checkout the latest code from the github repositiory. Alternative, for compiling a certain version, you can either checked that version from github or use it’s respective source tarball.
Manticore is a clean-slate research operating system, written in the Rust programming language, with the aim of exploring the parakernel OS architecture.
Why a new operating system? The OS is increasingly a bottleneck for server applications that want to take maximum advantage of the hardware. Many traditional kernel interfaces (such as in POSIX) were designed when I/O was significantly slower than the CPU. However, today I/O is getting faster, but single-threaded CPU performance has stagnated. For example, a 40 GbE NIC can receive a cache-line sized packet faster than the CPU can access its last-level cache (LLC), which makes it tricky for an OS to keep up with packets arriving from the network. Similarly, non-volatile memory (NVM) access speed is getting closer to DRAM speeds, which challenges OS abstractions for storage.
What is a parakernel? To address this OS bottleneck, server applications are increasingly adopting kernel-bypass techniques. For example, the Seastar framework is an OS implemented in userspace, which implements its own CPU and I/O scheduler, and bypasses the Linux kernel as much as it can. Parakernel is an OS architecture that eliminates many OS abstractions (similar to exokernels) and partitions hardware resources (similar to multikernels) to facilitate high-performance server application with increased application-level parallelism and predictable tail latency.

Roadmap
The development roadmap for Manticore is as follows:
Phase 0: kernel bootstrap, memory management, interrupts, etc. on Intel x86 platform with KVM/QEMU(done)Phase 1: UDP/IPv4 userspace network stack and VirtIO network device driver, and UDP echo server (done)- Phase 2: packet buffer management, virtual memory, and high-speed I/O interfaces (ongoing)
- Phase 3: multicore support on Intel x86 platform (ongoing)
- Phase 4: port memcached key-value store to the OS
- Phase 5: hardware NIC driver (e.g., for Intel 82599) with PCI device assignment under KVM/QEMU
- Phase N: managed runtime support (e.g.,Node.js or Wasmer)
There are also plans to port Manticore to the RISC-V and ARM64 machine architectures, please contact us if you are interested in helping out!
