Abstract

Energy Exascale Earth System Model (E3SM) simulations produce a large amount of output that often must be stored long-term. zstash provides this capability by archiving small files into larger tar files and then placing those tar files into the appropriate archive location, most often on a High Performance Storage System (HPSS). Other users can then use zstash to extract the contents of the archive. In this poster, we will outline new capabilities added in the latest releases and describe typical use cases.
