Output Control
--------------
-``GMX_CONSTRAINTVIR``
- Print constraint virial and force virial energy terms.
-
``GMX_DUMP_NL``
Neighbour list dump level; default 0.
(for coordinate and force buffers) directly on GPU memory spaces, without the staging of data through CPU
memory, where possible.
+``GMX_GPU_SYCL_NO_SYNCHRONIZE``
+ disable synchronizations between different GPU streams in SYCL build, instead relying on SYCL runtime to
+ do scheduling based on data dependencies. Experimental.
+
``GMX_CYCLE_ALL``
times all code during runs. Incompatible with threads.
``GMX_OCL_DISABLE_FASTMATH``
Prevents the use of ``-cl-fast-relaxed-math`` compiler option.
+ Not: fast math is always disabled on Intel devices due to instability.
``GMX_OCL_DUMP_LOG``
If defined, the OpenCL build log is always written to the
``GMX_OCL_NOGENCACHE``).
- NVIDIA GPUs: PTX code is saved in the current directory
- with the name ``device_name.ptx``
- - AMD GPUs: ``.IL/.ISA`` files will be created for each OpenCL
+ with the name ``device_name.ptx``
+ - AMD GPUs: ``.IL/.ISA`` files will be created for each OpenCL
kernel built. For details about where these files are
created check AMD documentation for ``-save-temps`` compiler
option.
