.. _system-requirements: Recommended minimum system requirements ####################################### |CL-ATTR| can run on most modern hardware and is capable of running with modest hardware resources. Out of the box, |CL| can run on a single CPU core, 1 GB RAM, and minimum of disk space of: * 4 GB for the *live server* * 20 GB for the *live desktop* .. caution:: Advanced users who wish to install on a disk using less than the recommended space requirements may use the flag ``--skip-validation-size``. Use of this flag may cause the installation to fail due to inadequate disk space. For use cases requiring minimal resources, |CL| :ref:`about ` can be used to create a highly customized installation that can even run on a system with a 128MB of memory and 600MB of disk space, for example. Installer requirements ********************** The *live desktop* installer requires at least 1 GB of RAM because more resources are required to run in live mode than after |CL| is installed onto persistent storage. For hardware with less resources, use the *live server* installer because it has a smaller memory footprint. See https://clearlinux.org/downloads for more download options. System requirements ******************* |CL| requires an x86 64-bit processor which supports Intel® Streaming SIMD Extensions 4.2 (Intel® SSE 4.2). For information on the boot loader, see the `clr-boot-manager readme`_ . The |CL| installer performs a system compatibility check upon booting. To manually verify system compatibility with |CL|, run the :ref:`compatibility check tool` or go to http://ark.intel.com and check for these features: * Instruction Set: - 64-bit * Instruction Set Extensions: - Supplemental Streaming SIMD Extension 3 (SSSE3) - Intel® Streaming SIMD Extensions 4.1 (Intel® SSE 4.1) - Intel® Streaming SIMD Extensions 4.2 (Intel® SSE 4.2) - Carry-less Multiplication (PCLMUL) The following processor families have been verified to run |CL|: * Intel® Core™ processor family (2nd generation or greater) * Intel® Xeon® E3-xxxx processor * Intel® Xeon® E5-xxxx processor * Intel® Xeon® E7-xxxx processor * Intel Atom® processor C Series * Intel Atom® processor E Series Recommended configurations ************************** For general |CL| desktop use the recommended minimum requirements include: ========= =============================== Component Configuration --------- ------------------------------- Processor Compatible x86 64-bit processor --------- ------------------------------- Memory 4GB RAM --------- ------------------------------- Disk 20 GB --------- ------------------------------- Graphics Device with openGL support (e.g. Intel HD/UHD Graphics) --------- ------------------------------- Network Active Internet connection ========= =============================== *Intel, Intel Core, Xeon, Intel Atom, and the Intel logo are trademarks of Intel Corporation or its subsidiaries.* .. _clr-boot-manager readme: https://github.com/clearlinux/clr-boot-manager
