It originated circa 1990 at the International Computer Science Institute at the University of California, Berkeley, developed by an international team led by Steve Omohundro. It supports garbage collection and generics by subtypes. Originally, it was based on Eiffel, but it has diverged, and now includes several functional programming features. It is probably best to view it as an object-oriented language, with many ideas borrowed from Eiffel. Even the name is inspired by Eiffel; the Sather Tower is a recognizable landmark at Berkeley. Sather also takes inspiration from other programming languages and paradigms: iterators, design by contract, abstract classes, multiple inheritance, anonymous functions, operator overloading, contravariant type system. Some of these features are normally only found in functional programming languages. Sather is implemented as a compiler to C, i.e., the compiler does not output object or machine code, but takes Sather source code and generates C source code as an intermediate language. Optimizing is by the C compiler, Sather code often performs better than the corresponding C++ code, and the generated C code can always be optimized by hand. Sather is dual licensed under the GNU GPL & LGPL.

Sather Interviews are getting tough these days as the technology grows faster. To get through the Sather interview one needs to update him/herself in a regular manner. Having said that, just before the interview, it is very important to have a quick glance of the reputed Sather questions and answers to make yourself comfortable during the interview process. This is where DoAnswers.com helps you in renewing yourself on Sather and various other technologies interview preparation.

11. What is the current version of pSather?

The current compiler version is 1.0.6.

12. What is the future of pSather?

We are currently working on a pSather runtime which implements nearly all the features described in the pSather specification. It will run on Solaris, Sun and Linux. The most notable difference to the current compiler will be the support of more than one cluster. As the runtime uses a small, but well defined interface to inter cluster communication and threads, it should be possible to port it to other computers without to much troubles.

13. When MAIN::main ends, the program stops even though there are still some threads running?

This is a known bug.
