17. Discussing Experiment Needs

Brian Bockelman, Dr Peter van Gemmeren (ANL)

This session we will discuss the needs of current and future experiments with respect to scalable IO on HPCs. This should follow on from the needs for ROOT, and discuss how experiments can then utilize extensions to take advantage of parallel IO at scale on HPCs.

18. Compression

This session will be focused on how compression impacts scalable IO in HEP experiments. Most experiments store their data using compression. Can we utilize non-CPU resources to do this? What would the impact be on uncompressing on CPUs if compressed on GPUs? What tools can we use? ROOT? ZLIB? VarInt? ProMC?
