Embodiment 1

[0019] Such as figure 1 As shown, a fixture for simulating GPU mechanical shock vibration, the structure of the fixture includes a fixture body 1, a blocking plate 2, and an external bracket 3, wherein the appearance size of the fixture body 1 is the same as that of the GPU computing card, and the fixture body 1 set with golden fingers.

Embodiment 2

[0021] On the basis of Example 1, the material of the treatment body 1 in this example is aluminum alloy.

Embodiment 3

[0023] On the basis of Embodiment 1 or 2, the GPU computing card described in this embodiment is an nvidia K40 GPU computing card.

[0024] The nvidia K40 GPU computing card is a commonly used GPU computing card at present. The core frequency of K40 has been increased from 732MHz to 745MHz. It supports GPU acceleration. The acceleration frequency can reach 875MHz. The memory frequency has also been increased from 5.2GHz to 6GHz. 384bit; the bandwidth has been increased from the previous 250GB / s to 288GB / s, the video memory capacity is matched with 12GB video memory, the video memory particles use 4Gb video memory, the total capacity of K40 has been increased to 12GB (24x4Gb), and supports PCI-E 3.0, K40 The bandwidth to and from the CPU has been increased from 8GB / s to 15.75GB / s.

Abstract

The invention discloses a tool for simulating GPU machinery impact and vibration, and the structure of the tool comprises a tool body, a baffle sheet, and an externally connected support. The appearance and the size of the tool body are identical to those of a GPU computer card. The tool body is provided with a golden finger. The tool is capable of simulating nvidia K40 GPU computer card for machinery testing and simulating real GPU for machinery impact and vibration testing, which reduces the testing risk and the testing fee.

Description

technical field [0001] The invention relates to the technical field of GPU shock vibration, in particular to a jig for simulating GPU mechanical shock vibration. Background technique [0002] GPU computing is the use of GPUs (graphics processing units) in combination with CPUs to accelerate general scientific and engineering applications. First introduced by NVIDIA® Corporation five years ago, GPU computing has quickly become an industry standard with millions of users worldwide and adopted by nearly all computing vendors. [0003] GPU Computing enables unprecedented application performance by offloading the computationally intensive parts of an application to the GPU while the remainder of the program remains running on the CPU. From the user's perspective, the application just runs a lot faster than before. [0004] With the rapid development of the server industry, more and more customers prefer to purchase large quantities of servers as their core applications. Higher...
