e36ee7e2d6 AC_multigpu_offset tested to work on at least 2 nodes and 8 GPUs. Forcing should now work with MPI 2020-03-25 13:51:00 +02:00

daa895d2fc Fixed an issue that prevented Ninja being used as an alternative build system to Make. There's no signifant performance benefit to using Ninja though. Build times: 29-32 s (Make) and 27-28 s (Ninja) 2020-02-10 14:37:48 +02:00

7b39a6bb1d AC_multigpu_offset is now calculated with MPI. Should now work with forcing, but not tested 2020-02-03 15:45:23 +02:00

50af620a7b More accurate timing when benchmarking MPI. Also made GPU-GPU communication the default. Current version of UCX is bugged, must export 'UCX_MEMTYPE_CACHE=n' to workaround memory errors when doing GPU-GPU comm 2020-02-03 15:27:36 +02:00

17c935ce19 Added padding to param name buffers to make them have NUM_*_PARAMS+1 elements. This should satisfy some strict compilation checks. 2020-01-28 18:53:09 +02:00

67f2fcc88d Setting inv_dsx etc explicitly is no longer required as they are set to default values in acc/stdlib/stdderiv.h 2020-01-28 18:22:27 +02:00

0ccd4e3dbc Major improvement: uniforms can now be set to default values. The syntax is the same as for setting any other values, f.ex. 'uniform Scalar a = 1; uniform Scalar b = 0.5 * a;'. Undefined uniforms are still allowed, but in this case the user should load a proper value into it during runtime. Default uniform values can be overwritten by calling any of the uniform loader funcions (like acDeviceLoadScalarUniform). Improved also error checking. Now there are explicit warnings if the user tries to load an invalid value into a device constant. 2020-01-28 18:17:31 +02:00

6dfe3ed4d6 Added out-of-the-box support for MPI (though not enabled by default). Previously the user had to pass mpicxx explicitly as the cmake compiler in order to compile MPI code, but this was bad practice and it's better to let cmake handle the include and compilation flags. 2020-01-28 15:59:20 +02:00
