1 About Gelato

1.1 What is the purpose of the Gelato Federation?

The Gelato Federation was launched to create a technical community whose purpose is to make the Itanium-based Linux platform more accessible to users of all types. You can get information about the Gelato Federation's mission at http://www.gelato.org/about/whatis.php.

Visit http://www.gelato.org/about/joining.php
for details about participation in Gelato.

1.4 Does Gelato recommend a specific GNU/Linux distribution?

No. We strive to be distribution agnostic.

1.5 I'm not involved with research; is Gelato of any benefit to me?

Yes. Though Gelato was established by the research community, the Gelato portal and contributions by the Gelato Federation should largely benefit all users of Linux on Itanium.

1.6 How old is Gelato?

The founding Gelato members and sponsor first met as a federation in January 2002. The Gelato Federation was announced in March 2002.

1.7 What are the Gelato members working on?

We have identified six focus areas: clustering, parallel file systems, single system scalability, performance tools for clusters and for single systems, and compilers. However, our members are involved in many different things.

Yes. The portal is intended to be a resource for everyone interested in Linux on the Itanium architecture.


2.3 How do I participate in the discussions?

There are two methods. One method is by visiting the web site, http://gelato.org. There you may click on "Create New Post" to start a new topic. Or you can respond to an existing post by clicking on the "comment" text next to this post's title. The other method is to subscribe to the gelato-technical mailing list.

4.1 Where can I find documents detailing the Itanium architecture?

You can find them at http://developer.intel.com/design/itanium2/manuals/.


4.2 What are Merced, McKinley, Madison and Montecito?

Merced was the internal project name for the first Itanium processor. McKinley was the internal name for the initial Itanium 2 processor. Madison and Montecito are internal codenames for Itanium 2 processors which were released after McKinley.


4.3 Are Itanium and IA-64 synonymous?

IA-64 was the name originally given to the Itanium architecture.


5 Software

5.1 What compilers are available for Linux on Itanium?

Compilers include GCC (http://gcc.gnu.org), the Open Research Compiler (ORC) (http://ipf-orc.sourceforge.net) and the Intel compilers (http://www.intel.com/software/products/compilers/)

5.2 What system performance tools are available for Linux/ia64?

Some of the available tools include:


5.3 Are there any technical documents about the Linux kernel as implemented on Itanium?

The book "IA-64 Linux Kernel: Design and Implementation" by David Mosberger and Ste'phane Eranian is a thorough description. The book's website (http://www.lia64.org/book/) maintains an errata that reflects changes to the kernel.

5.4 I'm interested in Itanium Linux kernel development, where do I begin?

The IA-64 Linux kernel changes can be found at http://www.kernel.org/pub/linux/kernel/ports/ia64/. You can subscribe to the Linux kernel mailing list at https://external-lists.valinux.com/lists/listinfo/linux-ia64/.
