01. System Requirements
Introduction
"NEQTO Engine for Linux" is a NEQTO service (daemon application) that runs on Linux devices. Various functions are available to manage user applications and systems via neqto.js.
The installation requirements for NEQTO Engine for Linux are as follows.
Hardware Requirements
Supported Architectures:
armv6l(32bit),armv7l(32bit),aarch64(64bit),x86_64(64bit)Required disk space (In default settings)
Location Required Size Use Notes /usr ≥ 2MB + INS Executable files /var ≥ 24MB + MD System files, User storage, User log /etc ≥ 1MB Configuration file /tmp ≥ 1MB + MD + INS NEQTO daemon log * MD: Increases depending on the file size used by the machine driver.
* INS: During software update, it temporarily increases by about2MB.Required RAM space: ≥ 4MB (In default settings)
Network Communication Interfaces:
A physical network adapter must be on board.
Software Requirements
- Must be a distribution that has
"systemd"support. - Consisting only of the standard C library pre-installed in the distribution, it basically works with just an executable file.
- Uses the real-time scheduling (
SCHED_FIFO) feature of the kernel. Therefore, it is required thatSCHED_FIFOprocessing resources are allocated in the system.
