GPU中计算不连通图的QUDA分支

A QUDA-branch to compute disconnected diagrams in GPUs

摘要:

虽然QUDA允许许多QCD量的有效计算,但令人惊讶的是,它缺乏评估断开图的工具,而GPU特别适合。我们的目标是通过创建我们自己的QUDA分支来填补这一空白,其中包括使用几种方法和费米子正则化计算费米子环所需的新内核和函数。

英文摘要:

Although QUDA allows for an efficient computation of many QCD quantities, it is surprinsingly lacking tools to evaluate disconnected diagrams, for which GPUs are specially well suited. We aim to fill this gap by creating our own branch of QUDA, which includes new kernels and functions required to calculate fermion loops using several methods and fermionic regularizations.
