论文摘要
在接下来的十年中,预计大型科学实验中对计算的需求将大幅增长。在同一时期,CPU性能提高将受到限制。在CERN大型强子对撞机(LHC),这两个问题将互相面对,因为对撞机的升级用于高光度。替代处理器(例如图形处理单元(GPU))可以解决这种对抗,只要算法才能充分加速。在许多情况下,通过采用深度学习算法,发现算法加速度最大。我们对基于GPU的硬件加速度在高能物理的数据重建工作流中的深入学习推断进行了全面探索。我们提出了几个现实的例子,并讨论了协处理器无缝集成的策略,以便LHC在整个运行过程中可以维持其当前的绩效。
In the next decade, the demands for computing in large scientific experiments are expected to grow tremendously. During the same time period, CPU performance increases will be limited. At the CERN Large Hadron Collider (LHC), these two issues will confront one another as the collider is upgraded for high luminosity running. Alternative processors such as graphics processing units (GPUs) can resolve this confrontation provided that algorithms can be sufficiently accelerated. In many cases, algorithmic speedups are found to be largest through the adoption of deep learning algorithms. We present a comprehensive exploration of the use of GPU-based hardware acceleration for deep learning inference within the data reconstruction workflow of high energy physics. We present several realistic examples and discuss a strategy for the seamless integration of coprocessors so that the LHC can maintain, if not exceed, its current performance throughout its running.
