Julian Hammer says:

Sandy Bridge and Ivy Bridge have problems with splitloads and small stencils containing a central point. This issue was raised to Intel, but no solution was offered. As of Haswell, the problem is resolved. Including `#pragma vector aligned` reduced the problem, but does not solve it completly. Removing the central point solves this issue.

How to test this stencil

Generate this stencil with:

stempel gen -D 3 -r 1 -t "double" -C constant -k star -o --store stencil.c

and generate the compilable benchmark code with:

stempel bench stencil.c -m IvyBridgeEP_E5-2660v2.yml --store

Compiler flags

icc -O3 -xAVX -fno-alias -qopenmp -qopenmp -DLIKWID_PERFMON -I/apps/likwid/4.3.4/include -L/apps/likwid/4.3.4/lib -I/headers/dummy.c stencil_compilable.c -o stencil -llikwid

Single Core Grid Scaling

ECM Prediction vs. Performance

Comparison of the measured stencil performance (in cycles per cache line), roofline prediction and the (stacked) contributions of the ECM Performance Model predicted by kerncraft using Layer Conditions to model the cache behavior. The calculated layer conditions shown above correspond to the jumps in the ECM prediction in this plot.

Data Transfers between Caches

Data transfers between the different cache levels and main memory. The shown data for each level contains evicted and loaded data. The measured data is represented by points and the predicted transfer rates by kerncraft by lines.

Multi Core Thread Scaling

How to replicate this data

Single Core Measurements

Using the generated stencil and kerncraft, all single core performance data shown on this page can be reproduced by:

Layer Condition Data

kerncraft -p ECM -p RooflineIACA -p Benchmark -p LC -P LC -m IvyBridgeEP_E5-2660v2.yml stencil.c -D N $GRID_SIZE -D M $GRID_SIZE -D P $GRID_SIZE -vvv --cores 1 --compiler icc

Cache Simulator Data

kerncraft -p ECM -p RooflineIACA -p Benchmark -p LC -P CS -m IvyBridgeEP_E5-2660v2.yml stencil.c -D N $GRID_SIZE -D M $GRID_SIZE -D P $GRID_SIZE -vvv --cores 1 --compiler icc

Thread Scaling Measurements

The generated benchmark code can be used to reproduce the thread scaling data shown on this page by:

kerncraft -p ECM -p RooflineIACA -p Benchmark -P LC -m IvyBridgeEP_E5-2660v2.yml stencil.c -D N $GRID_SIZE -D M $GRID_SIZE -D P $GRID_SIZE -vvv --cores $CORES --compiler icc

The roofline prediction can be obtained with kerncraft and the generated stencil:

kerncraft -p RooflineIACA -P LC -m IvyBridgeEP_E5-2660v2.yml stencil.c -D N $GRID_SIZE -D M $GRID_SIZE -D P $GRID_SIZE -vvv --cores ${threads} --compiler icc

Spatial Blocking Measurements

Generate benchmark code from the stencil with blocking and compile it as shown before:

stempel bench stencil.c -m IvyBridgeEP_E5-2660v2.yml -b 2 --store
