If you think advanced compiler optimizations are robust and well-tested, you are wrong. Our recent experiments with optimization testing have uncovered errors in every compiler technology that we got our hands on.
Our 1st Light paper – The Day that GNU-C++ -Os Broke.
We encounter a lot of compiler problems that require deeper research. Recently we hit on an interesting optimization error.
SuperTest – helping Graphcore accelerate the future of AI
Machine intelligence processor maker Graphcore (Bristol, UK) develops massively-parallel computing platforms that let innovators create next-generation AI products. As part of its compiler development tool chain, the company is using SuperTest to test and validate compilers for its unique Intelligence Processing Unit architecture.
