This is a very promising method to promote the CPU utilization(the long term average CPU utilization can reach 90%) on any clusters. Work on BelleII: Designed and implemented the BelleII dataset handling system in 2013; Developed volunteer computing project BelleII@home in 2015, the challege is to integrate the untrusted volunteer computing resources into the BelleII DIRAC system in a secure way. Applied and being selected by the KEK visiting scholar program respectly in 2013 and 2015, and worked on the above two topics.  Engaging the two Chinse HPCs(Tianhe-1 and ERA II) with ATLAS computing. Also, led and participated in other projects in grid computing, cloud storage system and site management.Volunteer Computing Interact with scientists in fields of high energy physics, bioinformation, genomics, nano technology, optimize the computing software and port them on heterogenous volunteer computing devices. R&D work on BOINC: scheduling, user interface, ARC CE/DIRAC plugin to BOINC. Cloud Storage: Main Architect and developer of a cloud storage system called Mucura which is based on Cassandra(distributed hash table storage systems)and provides Amazon S3 interface/authentication and also supports GSI authentication.
