Hello!
Can anyone tell me, is it possible to collect number of fetches and
cache misses for a particular array using Callgrind/Cachegrind?
For example, I have such fragment:
for (j = 0; j < length; j++) {
for (i = ip[j]; i <= ip[j+1]-1; i++) {
b[ia[i]] = b[ia[i]] + a[i]*x[j];
}
}
And I want to collect information only about array /b/. How can this be
done?
Thanks in advance!
