According to Agner's instruction table, the latency of instruction mulss is 5, and there are dependencies between the loops, so as far as I see it should take at least 5 cycles per loop. Could anyone shed some insight? The link is presented without commentary, but for those who do not know, Agner Fog manuals are pretty much the bible on x86 microarchitectural details and optimization. salicideblock 45 days ago Indeed. Agner Fog's "instruction_tables.pdf" is the most comprehensive single document for latency and throughput, with the added benefit of including AMD (and Via) processors and maintaining all the historical results in mostly the same presentation form.

Agner Fog Research Topics Culture theories interdisciplinary theories of cultural change, including cultural selection theory and regality theory. Evolutionary biology Software for simulating biological evolution processes in structured populations. Random number generator Pseudo random number generator, source code and documentation. 2014-08-08 · You show this in the instruction tables as 1 uop on Port 0 for 128-bit FP divide and 2 uops on Port 0 for 256-bit divide, but I had not seen anyone comment specifically on the absence of FP divide throughput speedup on AVX before, so I thought I would bring it up. These vary by CPU architecture, but the best resource currently for x86 timings is Agner Fog's instruction tables. Covering no less than thirty different microarchitecures, these tables list the instruction latency , which is the minimum/typical time that an instruction takes from inputs ready to output available.

It's a 2-fused-domain-uop instruction that only uses the store-data and store-address ports, not the shuffle unit. (Agner Fog's table lists it as using one p015 uop on SnB, 0 on IvB. Agner runs each platform through a laundry list of micro-targeted benchmarks, in order to suss out details of how they operate. The officially published instruction latency charts from AMD and Optimizing software performance using vector instructions.

Agner Fog is a Danish evolutionary anthropologist and computer scientist. He is currently an He maintains a five-volume manual for optimizing code for x86 CPUs, with details on the instruction timing and other features of individual&n

However, when I measure the throughput of my problem, the number are very low. Following the Table of Agner Fog [Agner Fog][1] page 242, the throughput of a `FMA` and `MUL` is 0.5. The definition of the throughput: is the time in [cycle] to perform a new identical mnemonic. Hmm, no, those latency timings appear to include an L1 access for some strange reason. Which did increase from 2 to 3 cycles.
