What is AVX512? AVX512 (Advanced Vector eXtensions) is the 512-bit SIMD instruction set that follows from previous 256-bit AVX2/FMA3/AVX instruction set. Originally introduced by Intel with its “Xeon Phi” GPGPU accelerators – albeit in a somewhat different form – it has finally made it to its CPU lines with Skylake-X … Read more…
What is NUMA? Modern CPUs have had a built-in memory controller for many years now, starting with the K8/Opteron, in order to higher better bandwidth and lower latency. As a result in SMP systems each CPU has their own memory controller and its own system memory that it can access … Read more…
What is “Threadripper”? “Threadripper” (code-name ZP aka “Zeppelin”) is simply a combination of inter-connected Ryzen dies (“nodes”) on a single socket (TR4) that in effect provide a SMP system-on-a-single-socket – without the expense of multiple sockets, cooling solutions, etc. It also allows additional memory channels (4 in total) to be … Read more…
