Does Sun Studio 12 software have both the Sun compiler and the integrated development environment (IDE) for Linux, as it has for the Solaris Operating System?

I'd like to set up an x86 server farm for in-house developer builds with the resulting build deployed on SPARC III-IV+ platforms. Can I do this with Sun Studio 12 software?

If you'd like answers to these questions, then check out the top 12 questions on Sun Studio 12 that developers asked and how Sun's experts answered them in this Q and A...

Sun's new UltraSPARC 2 processor can run up to 64 logical domains -- each with its own operating system. Sceptical? Check out this demo posted by Ashley Saulsbury at Sun Microsystems.

The new UltraSPARC T2 processor, with its 8 cores capable of handling 8 concurrent threads each, for a total of 64 threads, is a massively threaded server on a chip. Not only that, but it's faster and has more ports, more cache, more features than the T1 processor.

Watch Jonathan Schwartz and David Yen describe it here.

One of the new features in Solaris 10 now allows Solaris Containers to be moved from one system to another -- this new feature is currently available in Solaris Express, but will soon be available in a Solaris update.

Sun has published an excellent step-by-step guide on the process of moving Solaris Containers. You can view it at:

Sun has published an article which describes various tunables for Sun StorEdge SAN Foundation Suite -- also known as Leadville -- software. There are several areas of performance -- failover times, SCSI queue depth management, etc --
that can be optimised by judicious and careful use of certain user-tunable kernel-level variables.

This new document on sun.com presents three general matrices describing the various types of tunables and/or default values related to performance, failover times and error recovery and logging:

Type one (1) : variables may be adjusted to fit specific customer configuration requirements.

Type two (2) : variables are adjustable, but in general no adjustment is recommended. These variables need to be tuned only in very rare cases.

Type three (3) : variables are hard-coded and are not adjustable; they are presented herein for completeness only.

If you'd like to better understand the discovery, path failover and general performance tunables and values incorporated in the Leadville driver stack, simply download the PDF.
