+
+// -- OPERATING SYSTEM ---------------------------------------------------------
+
+
+
+// -- INTEGER PROPERTIES -------------------------------------------------------
+
+// The bit size of the integer type used to track values such as dimensions,
+// strides, diagonal offsets. A value of 32 results in BLIS using 32-bit signed
+// integers while 64 results in 64-bit integers. Any other value results in use
+// of the C99 type "long int". Note that this ONLY affects integers used
+// internally within BLIS as well as those exposed in the native BLAS-like BLIS
+// interface.
+#define BLIS_INT_TYPE_SIZE 64
+
+
+
+// -- FLOATING-POINT PROPERTIES ------------------------------------------------
+
+// Define the number of floating-point types supported, and the size of the
+// largest type.
+#define BLIS_NUM_FP_TYPES 4
+#define BLIS_MAX_TYPE_SIZE sizeof(dcomplex)
+
+// Enable use of built-in C99 "float complex" and "double complex" types and
+// associated overloaded operations and functions? Disabling results in
+// scomplex and dcomplex being defined in terms of simple structs.
+//#define BLIS_ENABLE_C99_COMPLEX
+
+
+
+// -- MULTITHREADING -----------------------------------------------------------
+
+// The maximum number of BLIS threads that will run concurrently.
+#define BLIS_MAX_NUM_THREADS 1
+
+
+
+// -- MEMORY ALLOCATION --------------------------------------------------------
+
+// -- Contiguous (static) memory allocator --
+
+// The number of MC x KC, KC x NC, and MC x NC blocks to reserve in the
+// contiguous memory pools.
+#define BLIS_NUM_MC_X_KC_BLOCKS BLIS_MAX_NUM_THREADS
+#define BLIS_NUM_KC_X_NC_BLOCKS BLIS_MAX_NUM_THREADS
+#define BLIS_NUM_MC_X_NC_BLOCKS 0
+
+// The maximum preload byte offset is used to pad the end of the contiguous
+// memory pools so that the micro-kernel, when computing with the end of the
+// last block, can exceed the bounds of the usable portion of the memory
+// region without causing a segmentation fault.
+#define BLIS_MAX_PRELOAD_BYTE_OFFSET 128
+
+// -- Memory alignment --
+
+// It is sometimes useful to define the various memory alignments in terms
+// of some other characteristics of the system, such as the cache line size
+// and the page size.
+#define BLIS_CACHE_LINE_SIZE 64
+#define BLIS_PAGE_SIZE 4096
+
+// Alignment size needed by the instruction set for aligned SIMD/vector
+// instructions.

+
+// Alignment size used to align local stack buffers within macro-kernel
+// functions.
+#define BLIS_STACK_BUF_ALIGN_SIZE BLIS_SIMD_ALIGN_SIZE
+
+// Alignment size used when allocating memory dynamically from the operating
+// system (eg: posix_memalign()). To disable heap alignment and just use
+// malloc() instead, set this to 1.
+#define BLIS_HEAP_ADDR_ALIGN_SIZE BLIS_SIMD_ALIGN_SIZE
+
+// Alignment size used when sizing leading dimensions of dynamically
+// allocated memory.
+#define BLIS_HEAP_STRIDE_ALIGN_SIZE BLIS_CACHE_LINE_SIZE
+
+// Alignment size used when allocating entire blocks of contiguous memory
+// from the contiguous memory allocator.

+// -- MIXED DATATYPE SUPPORT ---------------------------------------------------
+
+// Basic (homogeneous) datatype support always enabled.
+
+// Enable mixed domain operations?
+//#define BLIS_ENABLE_MIXED_DOMAIN_SUPPORT
+
+// Enable extra mixed precision operations?
+//#define BLIS_ENABLE_MIXED_PRECISION_SUPPORT

+// Stay initialized after auto-initialization, unless and until the user
+// explicitly calls bli_finalize().

+// -- BLAS COMPATIBILITY LAYER -------------------------------------------------
+
+// Enable the BLAS compatibility layer?
+#define BLIS_ENABLE_BLAS2BLIS
+
+// The bit size of the integer type used to track values such as dimensions and
+// leading dimensions (ie: column strides) within the BLAS compatibility layer.
+// A value of 32 results in the compatibility layer using 32-bit signed integers
+// while 64 results in 64-bit integers. Any other value results in use of the
+// C99 type "long int". Note that this ONLY affects integers used within the
+// BLAS compatibility layer.

+
+// -- CBLAS COMPATIBILITY LAYER ------------------------------------------------
+
+// Enable the CBLAS compatibility layer?
+// NOTE: Enabling CBLAS will automatically enable the BLAS compatibility layer
+// regardless of whether or not it was explicitly enabled above. Furthermore,
+// the CBLAS compatibility layer will use the integer type size definition
+// specified above when defining the size of its own integers (regardless of
+// whether the BLAS layer was enabled directly or indirectly).
