DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: Long running large scale HPC applications protect themselves from=0Afailures by periodically checkpointing their state to a single file=0Astored in a distributed network filesystem.  These filesystems=0Acommonly provide a POSIX-style interface for reading and writing=0Afiles.  HDFS is a filesystem used in cloud computing by Apache Hadoop.=0AHDFS is optimized for Hadoop jobs that do not require full POSIX I/O=0Asemantics.  Only one process may write to an HDFS file, and all writes=0Aare appends.  Our work enables multiple HPC processes to checkpoint=0Atheir state into an HDFS file using PLFS.  PLFS is a middleware=0Afilesystem that converts random I/O into log-based I/O.  We added a=0Anew I/O store layer to PLFS that allows it to use non-POSIX=0Afilesystems like HDFS as backing store.  HPC applications can now=0Acheckpoint to HDFS, allowing HPC and cloud to share the same storage=0Asystems and work with each others data.
