John Biddiscombe 053044ae4d 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.

Jerome Robert 1fe3aab047 Use GEMM_MULTITHREAD_THRESHOLD as a number of ops 
...not a matrix size. For GEMM_MULTITHREAD_THRESHOLD=4
(the default value) this does not change anything but
for other values it make the GEMM and GEMV thresholds
changing in the same way.

Jerome Robert 1a1935507b [z]ger: increase multithread threshold 
The ones given in 3ae30cd was by far to low because I
mixed m and m*n in my measures. Note that the new ones
are closed to the [z]gemv ones which is comforting
that both are right.

dimension does not change.

Hank Anderson 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
Hank Anderson b2284647a3 More complex objects. 2015-02-23 07:51:05 -06:00

Hank Anderson 9eb1499095 Added another param to GenerateNamedObjects to mangle complex source names. 
There are a lot of sources for complex float types that are the same
names as the real sources, except with z prepended.

Hank Anderson 4662a0b13a Changed generate functions to iterate through a list of float types. 
This will generate obj files for SINGLE/DOUBLE/COMPLEX/DOUBLE COMPLEX.

Hank Anderson e8c39138c6 Removed return value from GenerateNamedObjects. 
It sets DBLAS_OBJS directly to save a bunch of list appending in the
CMakeLists.txt files.

Hank Anderson 58cff2fed8 Added CBLAS define/naming convention to GenerateNamedObjects. 2015-02-04 11:30:15 -06:00
Hank Anderson 5690cf3f0e Added override for function names in GenerateNamedObjects. 
The BLAS interface folder should now be generated the correct objects
for the DOUBLE case.
 2015-02-04 10:52:19 -06:00
Hank Anderson a0aeda6187 Added function to set defines for the object names (e.g. -DNAME=dgemm). 2015-02-04 10:37:34 -06:00
Hank Anderson 20e593a44a Added cblas_ objects to interface CMakeLists. 
Naming isn't right, though, not seeing cblas_xxxx exports in the
resulting library.

Hank Anderson a6cf8aafc0 Updated level3/CMakeLists with correct defines using all combos. 2015-01-30 11:21:50 -06:00
Jerome Robert b17ccb4c5c Fix a segfault in gemv when MAX_STACK_ALLOC is set 
* stack_alloc_size is needed after the implementation call
but it may be overwritten if it's optimized to a register,
because some gemv implementation (ex: dgemv_n.S) do not
restore all register (ex: r10).
* do the same in ger.c for the same reasons even if the bug
has not been observed.
 2015-01-29 09:55:57 +01:00
Hank Anderson 5eefe18ae4 Added CMakeLists.txt for the first of the BLAS folders. 
It only does the double precision compile currently.

I realized I didn't finish converting Makefile.system yet, so I made
a note of that.

Jerome Robert e9d9a8eae3 Allow to do gemv and ger buffer allocation on the stack 
ger and gemv call blas_memory_alloc/free which in their turn
call blas_lock. blas_lock create thread contention when matrices
are small and the number of thread is high enough. We avoid
call blas_memory_alloc by replacing it with stack allocation.
This can be enabled with:
make -DMAX_STACK_ALLOC=2048
The given size (in byte) must be high enough to avoid thread contention
and small enough to avoid stack overflow.

Fix #478
