Idealne, aby kompilace byla na pocet jader nebo pocet jader*2.Uz som dlhsie nekompiloval, ako nastavim pocet jadier*2 pre kompilator?
HAL3000 Phantom Dream?. To je "herní monstrum" a docela by mělo zajímalo, jak to chodí pod Linuxem.

No, nestěžuji si. Už jsem počítal jednu náročnou úlohu, prostě jsem to nechal běžet přes několik nocí. Zase to žere úžasných 10 W.
Jinak ten test disku máš blbě, protože se ti do toho nezapočítává ten sync (zkus si time sleep 2 && sleep 4
).
AES 550 MB/s? Mně můj počítač dává 19 MB/sMne dava môj Toughbook 900Mhz - 29,8MB/s.
Dá ti blowfish přes 1 GB/s? (openssl speed bf-cbc)Skusím zajtra, pastnem...
No, nestěžuji si. Už jsem počítal jednu náročnou úlohu, prostě jsem to nechal běžet přes několik nocí. Zase to žere úžasných 10 W.Toughbook berie 12 - 18W
Jinak ten test disku máš blbě, protože se ti do toho nezapočítává ten sync (zkus si time sleep 2 && sleep 4).Jo presne, neuvedomil som si, zajtra opravim a pastnem spravne hodnoty... Dik
Zase to žere úžasných 10 W.
To je sice pěkné, ale jak je na tom poměr výpočetní výkon na jednotku energie? Kolik J sežere AES 1GB u tebe a kolik na nějakém jeho stroji.

Takáto mašina by si zaslúžila Solaris + ZFS alebo CentOS a skúsiť sa pohrať s virtualizáciou a vyžmýkať s toho čo sa dá...
Tak mi to nedalo a otestoval jsem sveho "predcasneho 14" jeziska":
