6.1.4 : CMakeLists.txt

Écrivons le fichier CMakeLists.txt :



On commence par définir le projet : 
1
2

project(PERFORMANCE_WITH_NAN)
cmake_minimum_required(VERSION 3.0)


Ensuite, on inclue les macros que l'on a déjà développé pour le produit de hadamard : 
1

include(${CMAKE_SOURCE_DIR}/Examples/1-HadamardProduct/multiplePerfTest.cmake)


On définie les différentes tailles de vecteurs qui seront les différents points de nos graphes (attention à avoir des multiples de 8 pour que les tests en fonctions intrisèques se passent bien) : 
1

set(CONFIG_SGEMM "16, 32, 64, 112")


Définissions ce qu'est un NaN (qui se signal) : 
1

set(NAN_DEF "std::numeric_limits<float>::signaling_NaN()")


Définissions ce qu'est un infini : 
1

set(INF_DEF "std::numeric_limits<float>::infinity()")


Définissons un nombre dénormalisé : 
1

set(DENORM_DEF "std::numeric_limits<float>::denorm_min()")


Testons avec le plus petit nombre possible (si on le multiplie par lui même il sera dénormalisé) : 
1

set(MIN_TO_DENORM_DEF "std::numeric_limits<float>::min()")


Voici les trois sources de base pour tous les tests de performances de cette partie : 
1
2

4

set(SGEMM_BASE_SRC sgemm_base.cpp main_sgemm.cpp)
set(SGEMM_SWAP_SRC sgemm_swap.cpp main_sgemm.cpp)
set(SGEMM_VECTORIZE_SRC sgemm_vectorize.cpp main_sgemm.cpp)
set(SGEMM_INTRINSICS_SRC sgemm_intrinsics.cpp main_sgemm.cpp)


Créons les tests de références : 
1

multiplePerfTestLogX("sgemmBase" sgemm base "" "${CONFIG_SGEMM}" ${SGEMM_BASE_SRC})
multiplePerfTestLogX("sgemmSwap" sgemm swap "" "${CONFIG_SGEMM}" ${SGEMM_SWAP_SRC})
multiplePerfTestLogX("sgemmVectorize" sgemm vectorize "${VECTORIZED_OPTION}" "${CONFIG_SGEMM}" ${SGEMM_VECTORIZE_SRC})
multiplePerfTestLogX("sgemmIntrinsics" sgemm intrinsics "${VECTORIZED_OPTION}" "${CONFIG_SGEMM}" ${SGEMM_INTRINSICS_SRC})


Nous pouvons également ajouter des graphes (mais il faut faire attention au nom des programmes que l'on compoare) : 
1

phoenix_plotPerfLogX("cmpSgemmSafe03" sgemm_base_O3 sgemm_swap_O3 sgemm_vectorize_O3 sgemm_intrinsics_O3)
phoenix_plotPerfLogX("cmpSgemmSafe0fast" sgemm_base_Ofast sgemm_swap_Ofast sgemm_vectorize_Ofast sgemm_intrinsics_Ofast)


Testons avec des NaN :

multiplePerfTestValueLogX("sgemmBaseNanO3" sgemm base nan -O3 "${NAN_DEF}"
			"" "${CONFIG_SGEMM}" ${SGEMM_BASE_SRC})
multiplePerfTestValueLogX("sgemmSwapNanO3" sgemm swap nan -O3 "${NAN_DEF}"
			"" "${CONFIG_SGEMM}" ${SGEMM_SWAP_SRC})

multiplePerfTestValueLogX("sgemmVectorizeNanO3" sgemm vectorize nan -O3 "${NAN_DEF}"

multiplePerfTestValueLogX("sgemmIntrinsicsNanO3" sgemm intrinsics nan -O3  "${NAN_DEF}"
			"${VECTORIZED_OPTION}" "${CONFIG_SGEMM}" ${SGEMM_INTRINSICS_SRC})


Testons avec des Inf :

multiplePerfTestValueLogX("sgemmBaseInfO3" sgemm base inf -O3 "${INF_DEF}"

multiplePerfTestValueLogX("sgemmSwapInfO3" sgemm swap inf -O3 "${INF_DEF}"

multiplePerfTestValueLogX("sgemmVectorizeInfO3" sgemm vectorize inf -O3 "${INF_DEF}"

multiplePerfTestValueLogX("sgemmIntrinsicsInfO3" sgemm intrinsics inf -O3  "${INF_DEF}"
			"${VECTORIZED_OPTION}" "${CONFIG_SGEMM}" ${SGEMM_INTRINSICS_SRC})


Testons avec des nombres dénormalisés : 
1

multiplePerfTestValueLogX("sgemmBaseDenormO3" sgemm base denorm -O3 "${DENORM_DEF}"
			"" "${CONFIG_SGEMM}" ${SGEMM_BASE_SRC})
multiplePerfTestValueLogX("sgemmSwapDenormO3" sgemm swap denorm -O3 "${DENORM_DEF}"

multiplePerfTestValueLogX("sgemmIntrinicsDenormO3" sgemm intrinsics denorm -O3 "${DENORM_DEF}"
			"${VECTORIZED_OPTION}" "${CONFIG_SGEMM}" ${SGEMM_INTRINSICS_SRC})


Essayons de régler le problème avec des nombres dénormalisés :

multiplePerfTestValueLogX("sgemmBaseDenormDazO3" sgemm base denormDaz -O3 "${DENORM_DEF}"

multiplePerfTestValueLogX("sgemmSwapDenormDazO3" sgemm swap denormDaz -O3 "${DENORM_DEF}"
			"-mfpmath=sse" "${CONFIG_SGEMM}" ${SGEMM_SWAP_SRC})

multiplePerfTestValueLogX("sgemmVectorizeDenormDazO3" sgemm vectorize denormDaz -O3 "${DENORM_DEF}"

			"${VECTORIZED_OPTION} ${DENORM_DAZ_OPTION}" "${CONFIG_SGEMM}" ${SGEMM_INTRINSICS_SRC})


Voyons ce qu'il se passe lorsque le calcul produit des nombres dénormalisés :

Il n'a fallu que quelques lignes pour créer tous les tests dont nous avons besoin.
