HYPERTHREADING IN INTEL PROCESSORS has been deemed a big no-no for OpenBSD which reckons the tech opens the floodgates to more “Spectre-class bugs”.
Hyperthreading is the name Intel has given its take on simultaneous multithreading, which in plain old English is a way to run parallel processes across the cores of a CPU rather than have an operation reliant on one of them.
But the folks at OpenBSD, who specialise in a free, open-source Unix-like operating system, have deemed Hyperthreading to be a security risk for the time being and as such have disabled it.
