7.10 LQCD
7.10.1 Introduction to LQCD
7.10.2 Common Used Softwares
Currently common used LQCD softwares in IHEP:
- Chroma: developed byUSQCDCollaberations
- QUDA：supported by NVIDIA, using GPU to perform lqcd calculations combined with sChroma。
- GWU-Code：developed by χQCD Collaberations.
7.10.3 Software Usages
7.10.3.1 Software Versions and Location
Before usingchroma,QUDAandGWU-Code, following commands must be excuted:
mkdir-p ~/privatemodulesln-sf /afs.ihep.ac.cn/soft/lqcd/modulefiles ~/privatemodules/lqcdecho"module load use.own">>/.bashrcsource~/.bashrcCheck softwares' versions:
