Spatter 2.0 Validation
This page details some of the tests performed to validate Spatter 2.0 versus 1.1 kernels.
Both versions of Spatter were compiled using the GNU GCC compiler with the OpenMP backend and Release build type. For v1.1, the -g flag was removed from line 247 in CMakeLists.txt for consistency with v2, ensuring both were compiled with similar flags. Additionally, the source code of v1.1 was changed to increase the number of warmup runs from 1 to 10; aligning it with the number of warmup runs used in v2.
Spatter v1.1 build command:
cmake -DCMAKE_BUILD_TYPE=Release -DBACKEND=openmp -DCOMPILER=gnu -B build_openmp -S . && make -j$(nproc) -C build_openmp
Spatter v2 build command:
cmake -DUSE_OPENMP=1 -B build_openmp -S . && make -j$(nproc) -C build_openmp
The assembly code generated by the GNU GCC compiler was disassembled from the v1.1 and v2 spatter binaries using objdump. This can be used to validate the kernels by comparing the instructions in the loop region of the kernels between v1.1 and v2. These loop regions can be identified using VTune or stepping through the code with gdb.
To get the assembly code for a specific kernel, the following workflow was used:
-
Run
objdump -t spatter | grep <kernel_name>to get a list of matching symbols -
Run
objdump --disassemble=<kernel_symbol> spatterto disassemble the kernel
Example with Scatter Kernel:
Output from objdump -t spatter | grep scatter

Spatter was profiled with VTune to record the number of loads, stored, and instructions retired in the kernels. These metrics were used to investigate the performance gap observed on different platforms for the scatter, multiscatter, and gather-scatter kernels. VTune's memory access analysis was used to associate the number of loads and stores with each disassembled instruction from the kernel. Similarly, VTune's microarchitecture exploration analysis was used to record the number of instructions retired in the kernels.
The same application parameters were provided to VTune for both the memory access analysis and microarchitecture exploration analysis, with the kernel (-k flag) varying depending on the specific kernel being tested. Furthermore, the same configurations for the memory access and microarchitecture exploration analyses were used for all of the kernels tested.

There is a performance gap between the 1.1 and 2.0 gather-scatter OpenMP kernels. This is shown in the output below, which was generated on an Intel Gold 6226R (Cascade Lake) platform. Note: the program arguments passed to Spatter are slightly different due to changes in version 2.0.

We note that this validation process demonstrated that the two codebases are performing the equivalent operations specifically for the gather and scatter kernels. However, due to the large number of changes (specifically C to C++ data structure migration), it is not feasible to get exact parity for the kernels between the two versions of Spatter. For this reason, we highly recommend that you use a consistent tagged version of the codebase for your benchmarking and any comparisons between architectures.
