About us

Welcome to COSSUS, the Canadian Open Source Software Unix System. We are an unincorporated institution which archive pkgsrc bulk build reports for various operating systems which support the sun4v architecture. Also, this organisation provides resources to generate build reports which are open to the public. SSH access is available to researchers who are developers and have commit bits on an open source operating system project or package management system.

COSSUS are not established nor conducted for profit nor form part of, nor are administered or directly or indirectly controlled by, a body that is established or conducted for profit. Our project is located in Montreal, CANADA. We have the following resources at our disposal:

The generic and test LDOMs can be used to test any bootable image before it's deemed stable or assigned a proper bulk build schedule. If some LDOMs aren't utilising all available memory during development or builds, some can be reallocated to other LDOMs or used to create new ones as OSes which support this platform increase.

Possible platforms

If developers for these OSes would like an LDOM on this system to test updated versions of their respective OSes, please contact us. There might have been other OSes which supported sun4v. This list doesn't pretend to be complete.

OSes which supported sun4v
Operating system Last version(s) Notes

Unallocated resources

Bulk build report archive

Coming soon.

Binary package library

Coming soon.


  1. Schedule bulk builds;
  2. Document network topology;
  3. Add developers resource page;
  4. Mail OS project lists;
  5. Host bulk build reports;
  6. Host binaries for respective platforms;


An Oracle SPARC T4-1 or Fujitsu M10-1 would be fine too! Nerds can dream...
