The app running onAMD EPYCCPUs seem to seem to have lazier GC behavior. They handle requests (cost) almost equally (via ELB load balancing). -52 is AMD EPYC CPU High memory usage task/proc/cpuinfooutputs { "cpuInfo": [ "processor\t: 0", "vendor_id\t: AuthenticAMD", "cpu family\t...
AMD's root of trust comes from a secure processor that runs separate code with an isolated ISA. The chips also have an AES-128 engine in the memory controllers, with the keys managed by thesecurityprocessor. As such, the keys are walled off from the x86 domain. The chip supports u...
the new EPYC processors have Spectre V4 SSB disabled via Prctl and Seccomp, __user pointer sanitization for Spectre V1, and on the Spectre V2 front make use of AMD Retpoline IBPB with conditional RSB filling via firmware.

On its current processors using its Zen core—Ryzen, Threadripper, and Epyc—new microcode provides equivalents to IPBP and STIBP. On prior generation processors using the Bulldozer family, microcode has added IBRS and IBPB. Zen escapes (again) Why no IBRS on Zen? AMD argues that Zen's new...
