DESCRIPTION:Speakers: André Brinkmann (Johannes Gutenberg University Main
 z)\nMany scientific fields increasingly use high-performance computing (HP
 C) to process and analyze massive amounts of experimental data while stora
 ge systems in today’s HPC environments have to cope with new access patt
 erns. These patterns include many metadata operations\, small I/O requests
 \, or randomized file I/O\, while general-purpose parallel file systems ha
 ve been optimized for sequential shared access to large files. Burst buffe
 r file systems create a separate file system that applications can use to 
 store temporary data. They aggregate node-local storage available within t
 he compute nodes or use dedicated SSD clusters and offer a peak bandwidth 
 higher than that of the backend parallel file system without interfering w
 ith it. We present GekkoFS\, a temporary\, highly-scalable file system whi
 ch has been specifically optimized for the aforementioned use cases. Gekko
 FS provides relaxed POSIX semantics which only offers features which are a
 ctually required by most (not all) applications. GekkoFS is\, therefore\, 
 able to provide scalable I/O performance and reaches millions of metadata 
 operations already for a small number of nodes\, significantly outperformi
 ng the capabilities of common parallel file systems.\n\nhttps://events.chp
