How many caches are there? How many caches are in multi-core systems? do you have a L1 cache per cpu and one shared L2? or is there a victim L3 cache? can you tell me something about the path through the cache? for example I look up for data in L1, but this was a miss. Then i look up in L2 this was also a miss. but the date will be in another L1 cache of another cpu. Is there a 1.5 or 2.5 hit? can you help me please? this is for my bachelorthesis thanks a lot felix -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkisOIwACgkQmH8OAwYoDBk0ugCgu6zzJEQWA9NldC4ekjOcWgIu cYIAoMquvbvAf/qA1WmjtROpq+R1X6Yb =JepB -----END PGP SIGNATURE-----
