[Nexus-developers] SZIP support for NeXus

[Pedro Vicente]

Hi Janik

I did a SZIP inclusion in NeXus while doing some benchmarks for the SNS 
HistoTool last year regarding use of NeXus with compression/chunking.
The issue was mentioned in the last NeXus meeting in October 2010 at ORNL.
I can send you more details about that SZIP inclusion if you're interested 
(there was a slight performance increase in speed and file size If I recall 
correctly).
Pedro
