DESCRIPTION:Paper\n\nSimurgh: A Fully Decentralized and Secure NVMM User S
 pace File System\n\nMoti, Schimmelpfennig, Salkhordeh, Klopp, Cortes...\n\
 nThe availability of non-volatile main memory (NVMM) has started a new era
  for designing storage systems. Designing NVMM-specific file systems is a 
 significant step towards the integration of NVMMs. Supporting millions of 
 files with scalable metadata required by most data-intensive applications 
 is often hindered by the kernel storage stack's poor scalability and high 
 footprint. Moving the file systems to user space, however, can compromise 
 security.\n\nThis paper introduces Simurgh, a hardware-assisted user space
  file system with decentralized metadata management and allows secure meta
 data updates from within the user space. Simurgh guarantees consistency, d
 urability and ordering of updates without sacrificing scalability. Securit
 y is enforced by only allowing NVMM access from protected user space funct
 ions, which can be implemented through two proposed instructions. Comparis
 ons with other NVMM file systems show that Simurgh improves metadata perfo
 rmance up to 18x and application performance up to 89% compared to the sec
 ond-fastest file system.\n\nTag: Reproducibility Badge, Cloud and Distribu
