SUMMARY:(RP16) HuronFS : Hierarchical, User-level and On-demand Burst Buff
 er File System
DESCRIPTION:Research Poster\n\n(RP16) HuronFS : Hierarchical, User-level a
 nd On-demand Burst Buffer File System\n\nXu, Sato, Matsuoka\n\nIn HPC cent
 ers, the performance of the parallel file systems (PFSs) cannot match the 
 dramatic leaps in computational performance, resulting in degradation in t
 he performance of data-intensive applications. Moreover, I/O interference 
 from other users further exacerbates the situation. Burst buffers, a group
  of dedicated buffer nodes, have been proposed to alleviate such performan
 ce gap by buffering the I/O data between compute nodes and PFSs. However, 
 integrating burst buffer into the HPC centers requires additional procurem
 ent, deployment, and maintenance. Hence it is not economically or logistic
 ally feasible to add a burst buffer system to every existing system. Moreo
 ver, physically deployed burst buffer has its designed capacity and perfor
 mance, which can hardly adapt to any demand changes. In this poster, we pr
 opose a software- and user-level on-demand burst buffer system, HuronFS, t
 o solve such challenges. HuronFS extends our previous work CloudBB by havi
 ng high-performance network and data swapping supports. HuronFS leverages 
 compute nodes to build a software-level burst buffer system. HuronFS is de
 signed entirely on user-level. Hence HuronFS can be easily deployed on any
  HPC center or can even be deployed for a certain job by a user. Moreover,
  HuronFS supports expending and shrinking total buffer capacity according 
 to the workload. We evaluate HuronFS on a supercomputer, the results show 
 that we can achieve up to 7 times speed up on sequential I/O performance c
 ompare to the NFS storage by using only two additional compute nodes. The 
 evaluation of real applications also shows that HuronFS can help to accele
 rate data-intensive applications.\n\nPasses: Conference Pass, File Systems
