Macro Definition Documentation

◆ _GRB_BSP1D_BACKEND

#define _GRB_BSP1D_BACKEND

Which ALP/GraphBLAS backend the BSP1D backend should use for computations within a single user process.

The ALP/GraphBLAS compiler wrapper sets this value automatically depending on the choice of backend– compare, e.g., the grb::BSP1D backend versus the grb::hybrid backend.

◆ _GRB_NO_EXCEPTIONS

#define _GRB_NO_EXCEPTIONS

Define this macro to turn off reliance on standard C++ exceptions.

Deprecated:: Support for this macro is being phased out.

Note: Its intended use is to support ALP/GraphBLAS deployments on platforms that do not support C++ exceptions, such as some older Android SDK applications.

Warning: The safe usage of ALP/GraphBLAS while exceptions are disabled relies, at present, on the inspection of internal states and the usage of internal functions. We have no standardised exception-free way of using ALP/GraphBLAS at present and have no plans to (continue and/or extend) support for it.

◆ _GRB_NO_LIBNUMA

#define _GRB_NO_LIBNUMA

Define this macro to disable the dependence on libnuma.

Warning: Defining this macro is discouraged and not tested thoroughly.

Note: The CMake bootstrap treats libnuma as a non-optional dependence.

◆ _GRB_NO_STDIO

#define _GRB_NO_STDIO

Define this macro to turn off standard input/output support.

Warning: This macro has only been fully supported within the grb::banshee backend, where neither standard iostream nor stdio.h were available. If support through the full ALP implementation would be useful, please raise an issue through GitHub or Gitee so that we may consider and plan for supporting this macro more fully.

◆ _GRB_WITH_LPF

#define _GRB_WITH_LPF

Define this macro to compile with LPF support.

Note: The CMake bootstrap automatically defines this flag when a valid LPF installation is found. This flag is also defined by the ALP/GraphBLAS compiler wrapper whenever an LPF-enabled backend is selected.
