Is OSI the Open Source Initiative?

And awesome on how the effort has gone.

Dear colleagues,


I'm submitting a paper to the Astronomical Telescopes + Instrumentation
chapter of SPIE. The topic is on Gemini's latest upgrade to OSI and
RTEMS. I'm looking for links to any citations

you believe I should include --especially regarding OSI and RTEMS.


More details on our project below.

Thank you for any input,


-Matt


Over the past years at The Gemini 8-meter Telescope Project, we have
planned and are currently executing a comprehensive upgrade to our
Real-time Control Systems. These systems were designed in the 90's
during the EPICS 3.12.x and early 3.13.x era. They are exclusively
standard VME with PowerPC or 68k CPU's, running VxWorks 5.4.x.


The principle upgrade goals were to establish a new EPICS 3.14.x
development environment integrated with SVN, and rooted in the OSI
framework allowing the migration to RTEMS. I'm pleased to announce that
with the dedication of so many EPICS contributors over the years, we're
seeing our dreams come to life! To date, Gemini has upgraded and
released to operations six systems at each site (12 IOC's). These
include:

Telescope mount control

8-meter primary mirror control

cassegrain rotator control

Telescope weather monitor

Camera calibration mechanism unit

Telescope Interlock system

Currently, two more systems -- The Telescope Control and Secondary
Mirror Control are actively under commissioning. In the coming months
we will also commission our Enclosure Control System and the
Acquisition and Guiding unit. This will complete our project totaling
upgrades to no less than 20 IOC's depending on 32 EPICS support modules
spanning two hemispheres! At Gemini we're grateful and indebted to the
countless names of contributors allowing us to secure a manageable
development environment into the 2020's and beyond.


Aloha,
