suffix style args
suffix off suffix on suffix kk
This command allows you to use variants of various styles if they exist. In that respect it operates the same as the -suffix command-line switch. It also has options to turn off or back on any suffix setting made via the command line.
The specified style kk refers to the optional KOKKOS package that SPARTA can be built with, as described in this section of the manual. The KOKKOS package is a collection of styles optimized to run using the Kokkos library on various kinds of hardware, including GPUs via CUDA and many-core chips via OpenMP multi-threading.
As an example, the KOKKOS package provides a compute_style temp variant, with style name temp/kk. A variant style can be specified explicitly in your input script, e.g. compute temp/kk. If the suffix command is used with the appropriate style, you do not need to modify your input script. The specified suffix (kk) is automatically appended whenever your input script command creates a new fix, compute, etc. If the variant version does not exist, the standard version is created.
If the specified style is off, then any previously specified suffix is temporarily disabled, whether it was specified by a command-line switch or a previous suffix command. If the specified style is on, a disabled suffix is turned back on. The use of these 2 commands lets your input script use a standard SPARTA style (i.e. a non-accelerated variant), which can be useful for testing or benchmarking purposes. Of course this is also possible by not using any suffix commands, and explicitly appending or not appending the suffix to the relevant commands in your input script.
