HP has freed AdvFS, its 64-bit filesystem, under the GPLv2.
The code contribution coincides, for example, with the current implementation of a Linux-enabled supercomputing grid environment on HP Integrity servers in southern Italy at the Southern Partnership for Advance Computational Infrastructures (SPACI), a previous user of Tru64 AdvFS on Unix.
Also built-in to HP’s Tru64 Unix OS, AdvFS is designed to provide 64-bit performance benefits such as a transaction journaling environment for file recovery in seconds, regardless of the size of the file system, and volume configuration on a single disk partition, an entire disk, or an aggregated volume.
Hopefully this will help free platforms gain ground in the 64-bit realm (as if they weren’t already ahead).
