In a move that could help boost the scalability of Linux for grids and other advanced 64-bit multiprocessor applications, HP has release its Tru64 Unix Advanced File System (AdvFS) source code to the open source community.
Originally limited mainly to 32-bit workgroup applications, Linux has been gaining ground on 64-bit platforms vs. Unix over the past few years, especially since the release of 64-bit processors from Intel and AMD.
But on the Unix side, HP still produces both HP-UX and Tru64, an operating system once jointly developed with IBM, the old Digital Equipment Corp. (later acquired by Compaq, which was itself acquired by HP), and others within the Open Software Foundation (OSF). Back in the '80s, the 64-bit OS was known as OSF/1, and the Foundation's final release was in 1994.
In July of last year, HP announced intentions to continue supporting Tru64 UNIX until at least 2012, with the next maintenance release, 5.1B-5, due in the second half of 2008.
Meanwhile, according to industry analyst firm IDC, HP led the Linux market with a 38.6 percent revenue share for the first quarter of this year. HP also held the number one Linux server market position in unit shipments, with a 36.4 percent market share.
