Replace CMAKE_SOURCE_DIR/CMAKE_BINARY_DIR with PROJECT_SOURCE_DIR/PROJECT_BINARY_DIR
...
If OpenBLAS is built using add_subdirectory(OpenBlas) as part of another project
then the paths set by CMAKE_XXX_DIR are relative to the parent project
and not the OpenBLAS project.

Use cmake to build OpenBLAS GENERIC Target on MSVC x86 64-bit.
...
Disable CBLAS and LAPACK.
2015-08-10 14:10:44 -05:00
9eaea02f33
Added additional gemm defines for complex types.
2015-02-25 09:39:11 -06:00
0d8e227ea7
Changed strategy for setting preprocessor definitions.
...
Instead of generating separate object files for each permutation of
defines for a source file, GenerateNamedObjects now writes an entirely
new source file and inserts the defines as #define c statements.
This solves a problem I ran into with ar.exe where it was refusing to
link objects that had the same filename despite having different paths.
2015-02-24 12:26:33 -06:00

Added zherk_kernel.c objects to driver/level3.
2015-02-19 16:19:56 -06:00

Changed generate functions to iterate through a list of float types.
...
This will generate obj files for SINGLE/DOUBLE/COMPLEX/DOUBLE COMPLEX.
2015-02-15 17:44:37 -06:00
e74462a3f5
Moved declarations to start of functions to satisfy MSVC C89 implementation.
2015-02-11 11:16:57 -06:00
056ba26755
Changed a number of inline calls to use __inline.
...
MSVC doesn't inmplement C99, so can't use the inline keyword. __inline
appears to work in MSVC and GCC.
2015-02-11 11:13:17 -06:00
e8c39138c6
Removed return value from GenerateNamedObjects.
...
It sets DBLAS_OBJS directly to save a bunch of list appending in the
CMakeLists.txt files.
2015-02-09 12:28:09 -06:00
627d5e7401
Added SMP objects to driver/level3.

2015-02-05 10:49:11 -06:00

Codes when define is absent are now a parameter to AllCombinations.
...
The level3 object names should now be correct.
2015-02-05 09:23:47 -06:00
cfaf1c678f
Added option to append define codes with an underscore.
...
Fixed the code array not getting reset on subsequent AllCombinations
calls.
2015-02-05 09:17:18 -06:00
0d7bad1f35
Changed GenerateObjects to append combination codes (e.g. dtrmm_TU).
2015-02-05 09:02:54 -06:00
d11bde60d0
DOUBLE define for DBLAS objects is now set in main CMakeLists.txt.
...
Since the objects are the same, could generate SINGLE/COMPLEX/etc here
without having to rewrite all the object enumeration code again.
2015-02-02 15:00:44 -06:00
5057a4b4df
Added openblas add_library call that uses DBLAS_OBJS ojbects.

2015-01-30 13:47:40 -06:00

2015-01-30 13:31:13 -06:00
7693887d61
Added empty set to the combinations generated by AllCombinations.
2015-01-30 13:01:11 -06:00
8d9b196e0d
Moved loop over define combos into a function.
...
This function takes a set of sources and a set of preprocessor
definitions. It will iterate over the sources and build an object
file for each combination of preprocessor definitions for each
source file.
2015-01-30 12:14:44 -06:00
a6cf8aafc0
Updated level3/CMakeLists with correct defines using all combos.
2015-01-30 11:21:50 -06:00
dbdca7bf0c
Added first pass at driver/level3 Makefile conversion.
...
Added a rather convoluted CMake function to find all combinations
of a given list. This will be useful for the object files that are
compiled multiple times with different combinations of preprocessor
definitions.

Refs #221 #246 . Fixed the overflowing stack bug in mutlithreading BLAS3.
...
When NUM_THREADS(MAX_CPU_NUNBERS) is very large ,e.g. 256.
typedef struct {
volatile BLASLONG working[MAX_CPU_NUMBER][CACHE_LINE_SIZE * DIVIDE_RATE];
} job_t;
job_t job[MAX_CPU_NUMBER];
The job array is equal 8MB.
Thus, We use malloc instead of stack allocation.
