Supercalculateur Jean Zay, nomm\u00e9 ainsi en l’honneur du ministre de l’\u00c9ducation nationale qui fut l’artisan, avec Jean Perrin, de la cr\u00e9ation du CNRS. Capable d’effectuer 13,9 millions de milliards d’op\u00e9rations par seconde dans sa configuration initiale install\u00e9e \u00e0 l’\u00e9t\u00e9 2019, ce supercalculateur converg\u00e9 permet d’\u00e9tendre les modes d’utilisation classiques du calcul de haute performance (HPC) \u00e0 de nouveaux usages pour l’intelligence artificielle (IA). En plus de ses 1 528 noeuds de 40 coeurs Intel Cascade Lake \u00e0 2,5 GHz, il comprend 261 noeuds \u00ab\u00a0converg\u00e9s hybrides acc\u00e9l\u00e9r\u00e9s\u00a0\u00bb compos\u00e9s chacun de 40 coeurs \u00e0 2,5 GHz et de 4 GPUs NVIDIA V100. Chaque noeud dispose de 192 Go de m\u00e9moire et chaque GPU de 32 Go. Con\u00e7u par Hewlett Packard Enterprise, ce supercalculateur HPE SGI 8600 a \u00e9t\u00e9 acquis en 2019 par le Genci (Grand \u00e9quipement national de calcul intensif) et est op\u00e9r\u00e9 par l’IDRIS, localis\u00e9 sur le plateau de Saclay.

puissance de calcul:<\/h2>\n\n\n\n

FLOPS (op\u00e9rations en virgule flottante par seconde) <\/p>\n\n\n\n

126 P\u00e9taflops<\/p>\n\n\n\n

D\u00e9finition simple : Un p\u00e9taflop repr\u00e9sente la capacit\u00e9 \u00e0 effectuer un million de milliards (10\u00b9\u2075) d’op\u00e9rations de calcul par seconde.<\/p>\n\n\n\n

puissance de m\u00e9moire:<\/h2>\n\n\n\n

500 T\u00e9ra Octets de m\u00e9moire <\/p>\n\n\n\n

1 t\u00e9raoctet = 1 000 000 000 000 octets (soit 10\u00b9\u00b2 octets) selon le syst\u00e8me d\u00e9cimal<\/p>\n\n\n\n

1 To = 1 000 Go (gigaoctets)<\/p>\n\n\n\n

1 To = 1 000 000 Mo (m\u00e9gaoctets)<\/p>\n\n\n\n

puissance \u00e9nerg\u00e9tique<\/h2>\n\n\n\n

En GigaWatts et il faut refroidir..<\/p>\n\n\n\n

1 Gigawatt = 1 000 000 000 Watts (un milliard de watts)<\/p>\n\n\n\n

Un PC classique pour comparer<\/h2>\n\n\n\n

un ordinateur de bureau core i9 par exemple se mesure en Teraflops (10^12) (1 Teraflops est d\u00e9j\u00e0 beaucoup)<\/p>\n\n\n\n
