Karsten, Two more questions: 1. Are you using a file system with vary large disk block sizes, such as Lustre or the NCAR GLADE system? The disk block size on desktop systems is typically 1KB or 8KB, whereas for high-performance platforms with Lustre and similar file systems, it can be much larger, e.g. 1MB or 4MB. 2. Are you using parallel I/O? --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: AHZ-822837 Department: Support netCDF Priority: Normal Status: Closed
