Build Requirements

Language

VT conforms to C++14.

VT can currently compile with many C++11 compilers as long as detector is disabled. The detector component provides extra static checks (e.g., type traits enforcement) but is not required for "correctness".

Library Dependencies

• MPI 3+
• OpenMP 3+ (??)
• GoogleTests (local VT unit and integration tests)

Supported Compilers

A supported compiler is one which a mainline VT build SHOULD be able to target. Other compilers are expected to work if they sufficiently implement the C++11/14 standard.

These are chosen due to usage in research and HPC builds. It is recommended to use newer compiler versions whenever possible.

• GNU compilers (gcc) >= 4.9.3
• Clang/llvm (clang) >= 3.9
• Intel compilers (icc) >= 18.0.0
• NVidia cuda compiler (nvcc) (10.1, 11.0)
• Portland Group (pgi) (??)
• IBM compilers (xlc) (??)

The list of supported compilers (and minimum versions) can change with newer VT releases.

Compiler Features

Tracing

Tracing requires __PRETTY_FUNCTION__, as first implemented as a GCC extension.
