The Linux Technologies project is tasked to perform systems research with the goal of creating technical leadership for HP's server and workstation products when coupled with the GNU/Linux operating system. Other project objectives include supporting HP's contribution to open source and encouraging the use of open source in research.

HP has been a leader in the effort to promote Linux on the Itanium architecture, and the Linux Technologies project has been at the forefront of the effort. A particular emphasis of the project is to perform research that enables Linux and Linux-based applications to fully exploit the Itanium architecture.
