(In [9070]) Refs #2334: Slabs for writing SNS histogrammed nexus files (currently disabled). Parallelized part of the algorithm for speed-up.

comment:3 Changed 10 years ago by Janik Zikovsky

(In [9086]) Refs #2334: SaveSNSNexus will use slabs for writing large banks, depending on available memory. Speed is still limited by the compression in NXS being single-threaded.

Vickie tells me that the fixes helped her writing speed a lot, so I'm calling this closed :)

Speed did improve. Just checked that this still works for TOPAZ_1867.
