Ma debian n'utilise-t-elle qu'un seul de mes processeurs?

bonjour!
Voila, j’ai fait tourner mencoder cet apres midi, et j’ai remarqué ça :

top - 18:28:12 up 2:37, 1 user, load average: 0.84, 1.21, 1.40 Tasks: 100 total, 3 running, 97 sleeping, 0 stopped, 0 zombie Cpu(s): 54.3%us, 1.5%sy, 0.0%ni, 43.7%id, 0.0%wa, 0.2%hi, 0.3%si, 0.0%st Mem: 3116496k total, 2362248k used, 754248k free, 17536k buffers Swap: 570268k total, 76k used, 570192k free, 2138404k cached

La ligne important, c’est celle du cpu : on dirais que le processus n’utilise que la moitié du processeur. En effet, j’ai un processeur double coeur.
Y a t il un souci ou bien n’ai-je pas tout compris?

Merci d’avance!

ps : il n’y a pas que avec mencoder que cela se produit, mais avec tou les processus gourmands en cpu.

on sait jamais :

Installes le paquet htop et lances la commande htop.
Tu verras une interface similaire à top mais à l’avantage de voir un barre par processeur et donc tu verras combien de proc sont détecté.

Sinon que donne la commande :

[quote=“thuban”]xavier@Lothlorien:~$ uname -r

C’est une 32bit. je ne crois pas qu’il utilise les multi-coeurs.

#4

salut,
pour dmi decode, dans la section Processor Information

à la fin tu devrais avoir un truc du genre:
Core Count: 2
Core Enabled: 2
Characteristics:
64-bit capable

or ce n’est pas le cas. à priori, tu as fais une installation 32 bits sur ton système…

#5

Fait un

cat /proc/cpuinfo

et donne également ton noyau (idéalement, ça doit être un SMP pour qu’il puisse exploiter le double coeur).

bonsoir (ou bonjour).

Il semblerait que j’ai un cpu01 et un cpu1, donc bien un double coeur comme il le faut. C’est ça ou je suis trop fatigué pour bien comprendre? Dans ce cas pourquoi utiliser au maximum 50% du cpu?

:open_mouth: Seules les 64 bits utilises les multi coeurs? Cependant mon processeur n’est pas un amd64 (ou un truc du genre), c’est un 32 bit, pourtant il est multi coeur. Je ne comprend pas tout, vous pourriez m’expliquez svp?
Comment savoir si je peux faire une installation 64 bit? est-ce la seule solution?

Ah, une autre question, qu’est ce qu’on noyau SMP? J’ai installé le noyau proposé dans les dépots, le linux-image-2.6.26-1.686

Un noyau qui prend en charge le Symmetric multiprocessing [1].

Merci pour les explications! Maintenant, je vais sortir la question à laquelle je croyais connaitre la reponse depuis longtemps : quel noyau dois-je choisir, et comment puis-je le savoir?
je ne peux pas prendre un amd64 n’est-ce pas?
C’est dingue, je ne pensais pas en arriver là!

#10

Je crois pouvoir apporter un élément de réponse (j’avais cliqué y’a 5 minutes sur envoyer pile au moment ou ma connexion internet a foiré…)

J’ai un double-coeur AMD64 chez moi (6000+, pour les détails) et quand je regarde la courbe d’utilisation des proceusseurs, (moniteur système de GNOME) il alterne les deux.

J’en ai déduit que c’est pour le refroidissement.

Peut-ètre a tu fait le test quand un des coeurs refroidis.

Edit: J’ai pris le noyau AMD64, je crois que ça aide.

#11

Salut,

si j’en crois ceci: intel.com/products/processor … v+list_c2d

ton prosso est un 64 bits. d’après mes recherches il n’y a pas sur le marché de processeurs multicoeurs en 32 bits.
ce qui est confirmé par ton cat cpuinfo sur la ligne: clflush size : 64

mais je ne pense pas que de changer seulement le noyau sera suffisant, il faut que tu changes l’architecture de ta distribution (actuellement i386 probablement), pour profiter des programmes compilés en 64 bits.

et tu peux prendre la version amd64 pour ton install, il n’y aura pas de problèmes.

#12

j’ai essayé le noyau amd64, ça tourne bien je dois dire. Enfin si je n’ai d’autres choix que la réinstall, tant pis, je vais la faire! J’ai fait les test avec devede, en amd64, je tourne jusuq’à 80% de cpu, avec le dernier noyau i386, jusuq’à 70%. (eh oui, avec le dernier les 2 sont utilisés.) L’idée du refroidissement d’un des procs semble possible en effet.
Bon, eh bien si cette ligne me dit que je peux le faire en amd64, eh bien c’est parti!
Merci à tous pour vos réponses!

Oh, juste pour être sûr que je puisse faire l’install en 64, voici mon pc (car je n’ai jamais vu de mention 64, c’est pour ça que je m’interroge un peu) :

c’est exactement ce qui se passe, vérifié avec htop :wink: .

c’est mieux non? je n’ai pas ces lignes ci : [quote=“Anthropo”]salut,
pour dmi decode, dans la section Processor Information

à la fin tu devrais avoir un truc du genre:
Core Count: 2
Core Enabled: 2
Characteristics:
64-bit capable

or ce n’est pas le cas. à priori, tu as fais une installation 32 bits sur ton système…[/quote]

#15

Donne le résultat de uname -a
[edit: Hum, j’avais du retard]
Donne plutôt

cat /boot/config-`uname -r` | grep SMP
et cherche

[quote]CONFIG_X86_SMP=y
CONFIG_SMP=y
[/quote]
Si tu n’as pas un noyau SMP, il te suffit dans installer un.
Les deux cpu apparaissent dans /proc/cpuinfo.
Donne enfin «dmesg | grep CPU» et «dmesg | grep cpu»
Je pense que tes deux CPU sont reconnus.

PS: Le double coeur peut être aussi géré par un 32 bits à ma connaissance.

Ca veut dire que j’ai fait une réinstall en 64 bit pour rien?

Ben oui pour le support du double corps et non dans la mesure où le 64 bits te permet de profiter vraiment à plein de ta machine. Si jamais tu as des soucis, tu peux toujours faire un chroot 32 bits transparent (cf http://forum.debian-fr.org/viewtopic.php?f=8&t=14673).

#18

oui, j’ai toujours le support 64 bits! moi qui croyait dur comme ferme que j’avais un 32… :blush:
Je ne rencontre pas de soucis, tous les pilotes fonctionnent. Juste firestarter, mais j’ai pas torp cherché, ça devrait se régler bien vite.
Eh bien merci à tout le monde pour vos conseils!

#19

j’ai pas dit le contraire.c’est dommage d’avoir une architecture 64 et de ne la faire fonctionner qu’en 32. (comme un windoz vistouille quoi)

pour les lignes:
Core Count: 2
Core Enabled: 2
Characteristics:
64-bit capable

je les ai chez moi (proc AMD 64), à priori cette observation n’est pas transposable pour les processeurs intel…
