The development of Cray cooling technology allowed each technology
generation to increase the circuit board density. "Someone (perhaps Gary
Smaby? I truly don't remember) once said that Cray Research was primarily a
refrigerator company."
Cray-1: Single sided boards clamped to copper plates placed in aluminium
racks that had cooling fluid in tubes.
XMP: Double side sandwich boards clamped to twin copper plates placed in
aluminium racks which had cooling fluid in tubes.
Cray-2,3,4: Immersion cooling. The CPU and memory boards sat in a bath of
electrically inert cooling fluid.
YMP, C90, T3d LC, T3e MC: Double-sided circuit boards clamped to hollow
aluminium boards in which the cooling fluid circulated.
El,J90,T3eAC,SV-1: Blown air cooling.
T90: Immersion cooling. The CPU and memory boards sat in a bath of
electrically inert cooling fluid.
So the main forms of cooling were conduction to external cooling, conduction
to internal coolant, blown air cooling and total immersion cooling. There
was some research done into sprayed coolant methods for J90 modules,
reported in an internal technical symposium paper, but this did not make it
into a publicly available product.
attend, attend, j'ai peut etre trouvé :dun peu normal, tu crois pas ?
lol, j'avait la meme chose
simulation nucléaire, aerodynamique, thermodynamique, météorologique, prévisions boursières, prévisions dans les assurances, études de faisabilité, statistiques poussées...et ce genre de machine c'est utilisé pour faire quoi ?
des des itaniums 2 dedans :/C'est mieux Silicon Graphics SGI Prism Extreme Level

Tu peux voir sa configuration et son prix

Silicon Graphics est toujours une machine de rêve.
Pour les clusters,

Je vous laisse baver sur ces ordinateurs
Si tu veux des MIPS, voici SGI Origin 3000 Seriesdes des itaniums 2 dedans :/
dommage pour une si belle bête...
j'aurais préféré des MIPS [:lol2]
