    How much RAM do I have on Linux?

    To see the total amount of installed physical RAM you can run sudo lshw -c memory which will show you each installed RAM bank along with the total amount of system memory. This will likely be represented as a GiB value, which you can multiply by 1024 again to get the MiB value.

    What are CPU cores in Linux?

    We can get the number of physical and logical CPU cores using lscpu command in Linux as follows. … These threads are the logical capabilities of the kernel. The total number of logical cores = CPU sockets × physical cores per socket × threads per physical core. Therefore, the computer has a total of 2 × 8 × 2 = 32 logical cores.

    How to enable all cores in Linux?

    There is a “-j” command or extension that is used to specify how many cores you want to use to run a command. For example, if you have an Intel i7 processor with 4 cores, you can just append “-j4” to the end of your command and it will run with all four cores.
