Random device.
For now this is identical to the standard library, but since we use the GROMACS random module for all other random engines and distributions it is convenient to have this too in the same module.

Enumerated values for fixed part of random seed (domain)
Random numbers are used in many places in GROMACS, and to avoid identical streams the random seeds should be different. Instead of keeping track of several different user-provided seeds, it is better to use the fact that generators like ThreeFry take two 64-bit keys, and combine a general user-provided 64-bit random seed with a second constant value from this list to make each stream guaranteed unique.

int gmx::runCommandLineModule | ( | int | argc, |
char * | argv[], | ||
ICommandLineModule * | module | ||
) |
Implements a main() method that runs a single module.
This method allows for uniform behavior for binaries that only contain a single module without duplicating any of the implementation from CommandLineModuleManager (startup headers, common options etc.).
The signature assumes that module
construction does not throw (because otherwise the caller would need to duplicate all the exception handling code). It is possible to move the construction inside the try/catch in this method using an indirection similar to TrajectoryAnalysisCommandLineRunner::runAsMain(), but until that is necessary, the current approach leads to simpler code.
Usage:
Does not throw. All exceptions are caught and handled internally.

Prefetch memory at address m.
This typically prefetches one cache line of memory from address m, usually 64bytes or more, but the exact amount will depend on the implementation. On many platforms this is simply a no-op. Technically it might not be part of the SIMD instruction set, but since it is a hardware-specific function that is normally only used in tight loops where we also apply SIMD, it fits well here.
There are no guarantees about the level of cache or temporality, but usually we expect stuff to end up in level 2, and be used in a few hundred clock cycles, after which it stays in cache until evicted (normal caching).
m | Pointer to location prefetch. There are no alignment requirements, but if the pointer is not aligned the prefetch might start at the lower cache line boundary (meaning fewer bytes are prefetched). |
