Theoretical peak performance (Gflops) of the Intel Xeon CPU

AMale2 — Fri, 19 Jan 2018 08:58:25 GMT

What is the Theoretical peak performance (Gflops) of the Intel Xeon CPU E7-8860 v4 @ 2.20GHz/18cores?

- The document ( https://www.intel.com/content/dam/support/us/en/documents/processors/xeon/sb/xeon_E7-8800.pdf) I found - 90,64 Gflops for one CPU "Xeon E7-8860". But on my server with eight CPU (E7-8860) and test Linpack (l_mklb_p_2018.1.009 - Shared-memory version of Intel(R) Distribution for LINPACK* Benchmark) showed the result - 2264.2341 Gflops (No turbo boost). So the Linpack performance of one processor is 283.02926 Gflops (2264.2341 / 8). How can this be, what am I doing wrong?
