How might I use uGFS to efficiently access SX-6 files from Gale?
uGFS is a system to enable high performance access to the SX-6 GFS filesystems from a host outside the SX-6 cluster. The uGFS mounted filesystems are not fully equivalent to local filesystems and must be accessed only by programs which use special uGFS-aware I/O calls. There are (at least) two mechanisms for making programs able to use uGFS. • recompile, linking with the uGFS libraries. Some common utilities have been recompiled for gale users and can be used if you set up your PATH appropriately • pre-load uGFS libraries when you run your program. NEC supply a wrapper script to simplify this. You will need to ensure that your environment is set up for uGFS.
