Abstract

The utility model relates to graphics processing unit (GPU) extending, in particular to an external GPU extending device which is achieved through a GPU node. A GPU card is externally arranged, so that limitation of a GPU card space, power supply and radiating is avoided. Two GPU cards can be arranged in an extending mode through PCIE Switch in a PCIE * 16 groove in a server main board. The server main board is connected with the GPU node through a special transition card and a Cable.

Description

A kind of external GPU card expanding unit

Technical field

The utility model relates to the expansion of graphic process unit (GPU), is specifically related to a kind of external GPU card expanding unit.

Background technology

Along with the development of GPU technology, the application of GPU is also in continuous expansion, and a lot of application software are also progressively being drawn close to GPU.CPU+GPU Heterogeneous Computing has become the trend of high-performance calculation.In up-to-date TOP500 list, most machine is all to accelerate to realize high computing power by means of NVIDIA Tesla GPU.

In prior art, the interface shape of GPU card is PCIE x16, and GPU card is to be all inserted on the PCIE x16 slot of server master board.Server Extension GPU card is subject to following condition restriction:

(1) the own physical dimension of GPU card.GPU card power dissipation ratio is higher, himself initiatively or passive radiator size larger, expand polylith GPU card, server inner space is restricted;

(2) PCIE x16 groove Limited Number on server master board, can not expand enough GPU cards;

(3) GPU card power consumption is at 200W between 300W, and in server, not expanding polylith GPU card is also challenge to server radiating and power supply.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of external GPU card expanding unit, and this device is external by GPU card, has solved GPU card space, power supply and heat radiation restriction; On server master board, 1 PCIE x16 groove is by 2 GPU cards of PCIE Switch expansion; Server master board and GPU node are realized interconnection by special-purpose adapter and Cable.

The purpose of this utility model is to adopt following technical proposals to realize:

The utility model provides a kind of external GPU card expanding unit, and its improvements are, the realization of described device employing GPU node, and described device is connected with server master board by cable.

Further, described GPU node comprises PCIE bus switch chip, is provided with three PCIE x16 ports on described PCIE bus switch chip, and one of them PCIE x16 port is uplink port, is connected to PCIE x16 the first slot; Two other PCIE x16 port is downlink port, is connected respectively PCIE x16 the second slot and PCIE x16 the 3rd slot.

Further, described PCIE x16 the first slot connecting interface transforms card, converts PCIE x16 signaling interface to external interface, and described external interface is connected with PCIE x16 by cable.

Further, described PCIE x16 the second slot and PCIE x16 the 3rd slot are respectively connected with respectively two GPU cards.

Further, described GPU node comprises power supply interface, by power supply interface, is that GPU node is powered.

Further, described server master board and GPU node are realized interconnection by adapter and PCIE x16 cable.

Compared with the prior art, the beneficial effect that the utility model reaches is:

1, the utility model is external by GPU card, has solved GPU card space, power supply and heat radiation restriction, and the GPU card of expansion does not take server inner space;

2, on server master board, 2 GPU cards can be expanded in a PCIE x16 groove position, increase the quantity of expansion GPU card;

3, this device can be independently-powered and heat radiation, do not take server resource.

Accompanying drawing explanation

Fig. 1 is the structural representation of the external GPU card expanding unit that provides of the utility model.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.

The utility model provides a kind of external GPU card expanding unit, and as shown in Figure 1, this device adopts GPU node to realize to its structural representation, and server master board and GPU node are realized interconnection by adapter and PCIE x16 cable.。

A) in GPU node, PCIE bus switch chip (PCIE Switch) chip has 3 PCIE x16 ports, one of them port is uplink port, be connected to PCIE x16 the first slot (PCIE x16Slot1), two other PCIE x16 port is downlink port, is connected respectively PCIE x16 the second slot (PCIE x16Slot2) and PCIE x16 the 3rd slot (PCIE x16Slot3);

B) PCIE x16Slot1 connects an interface and transforms card, and PCIE x16 signaling interface is converted to externally can be by the interface of cable interconnection;

C) PCIE x16Slot2 and PCIE x16Slot3 respectively connect respectively two GPU cards;

D) GPU node comprises power supply interface, by power supply interface, is that GPU node is powered.

The utility model has solved the problem that Server Extension GPU card is subject to condition restriction, external by GPU card, has solved GPU card space, power supply and heat radiation restriction; On server master board, 1 PCIE x16 groove is by 2 GPU cards of PCIE Switch expansion.

Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although the utility model is had been described in detail with reference to above-described embodiment, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement embodiment of the present utility model, and do not depart from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of claim scope of the present utility model.
