1. A computing blade for a multi-blade supercomputer, said computing blade comprising:
a motherboard, comprising a plurality of processors mounted to a support;
a cold plate, dimensioned to cover the support of the plurality of processors, and comprising
a plurality of heat sinks,
a cooling circuit comprising channels inside which a cold heat transfer fluid that supplies the plurality of heat sinks circulates, and
a discharge circuit comprising channels inside which a hot heat transfer fluid that has heated up through the plurality of heat sinks,
wherein each heat sink of the plurality of heat sinks is mounted in line with a corresponding processor of the plurality of processors in order to cool the corresponding processor by heat exchange; and,
a plurality of network cards of a same number as said plurality of processors,
wherein each network card of said plurality of network cards is associated with a processor of said plurality of processors,
wherein said each network card comprises a plug-in end configured to receive a connector,
wherein said each network card is configured to allow data communication between said processor and another processor of said plurality of processors,
wherein said each network card is mounted to the cold plate by being connected to the motherboard via a connection system,
wherein said connection system comprises
a first connector, connected to the plug-in end of the each network card, and
a second connector, connected on one hand to the first connector via a cable and on another hand to the motherboard.
