Piste de recherche

Commencez par le reproducteur cblas_dgemm fourni et exécutez-le sous ThreadSanitizer. Examinez driver/others/memory.c, en particulier alloc_mmap, ainsi que driver/others/blas_server.c autour de blas_thread_server et de l'initialisation des threads. La tâche est terminée lorsque les conditions de concurrence signalées ont été identifiées et corrigées sans modifier le comportement BLAS attendu de l'exemple.

Description

#include <cblas.h>
#include <stdio.h>

int main()
{
  int i=0;
  double A[6] = {1.0,2.0,1.0,-3.0,4.0,-1.0};
  double B[6] = {1.0,2.0,1.0,-3.0,4.0,-1.0};
  double C[9] = {.5,.5,.5,.5,.5,.5,.5,.5,.5};
  cblas_dgemm(CblasColMajor, CblasNoTrans, CblasTrans,3,3,2,1,A, 3, B, 3,2,C,3);

  for(i=0; i<9; i++)
    printf("%lf ", C[i]);
  printf("\n");
}

results in

Output of running example compiler with tsan
