Macro Definition Documentation

◆ AURYN_CODE_USE_MPI

#define AURYN_CODE_USE_MPI

Compiler flag that determines whether Auryn is built using MPI or not.

◆ CODE_ACTIVATE_PREFETCHING_INTRINSICS

#define CODE_ACTIVATE_PREFETCHING_INTRINSICS

Toggle prefetching in spike backpropagation.

Enables prefetching for spike backpropagation in some plastic connections.

◆ CODE_ALIGNED_SIMD_INSTRUCTIONS

#define CODE_ALIGNED_SIMD_INSTRUCTIONS

Toggles between memory alignment for SIMD code.

◆ CODE_USE_SIMD_INSTRUCTIONS_EXPLICITLY

#define CODE_USE_SIMD_INSTRUCTIONS_EXPLICITLY

Toggle between explicit implementation for SIMD operations in AurynVector classes.

Even if you do not enforce this here, the compiler might still choose to use them when mtune settings are set appropriately.

◆ DEFAULT_MINDISTRIBUTEDSIZE

#define DEFAULT_MINDISTRIBUTEDSIZE 16

Groups with an effective size smaller than this will not be distributed.

Furthermore groups that are distributed will not be cut up in chunks that are not smaller than this. This is done to reduce overhead

◆ DEFAULT_TRACE_MODEL

#define DEFAULT_TRACE_MODEL Trace

These precompiler directives are deprecated and should not be used any more.

◆ MINDELAY

#define MINDELAY 8

Switches collection of timing stats in some classes like SyncBuffer and system.

This is for profiling and since it impairs simulation performance, it is disabled by default.

System wide minimum delay which determines the sync interval between nodes in units of auryn_timestep.

Per default this is set to 8 which corresponds to 0.8ms with Auryn standard auryn_timestep timestep of 0.1ms. The resaon for setting it to 8 is that the compiler can then implement certain operations using MINDELAY with va bitshift instead of regular division. However, the effect of this is presumably negligible, but I am keeping this for hystoric reasons.

◆ PRE_TRACE_MODEL

#define PRE_TRACE_MODEL Trace

◆ SIMD_NUM_OF_PARALLEL_FLOAT_OPERATIONS

#define SIMD_NUM_OF_PARALLEL_FLOAT_OPERATIONS 4

Use Intel Cilk Plus – only has an effect when CODE_USE_SIMD_INSTRUCTIONS_EXPLICITLY is enabled.

Use this when using an Intel compiler and CPU. This is for instance what you want when running on Xeon Phi.

Sets the number of floats your CPU can handle in parallel using SIMD

Since Auryn currently only supports SSE and not the new AVX 512, this is typically 4.
