Martin Kroeker	20c6c38e51	Merge branch 'develop' into atomic	7 years ago
Martin Kroeker	8ec28ff461	Remove unguarded use of _Atomic and fix tabbing	7 years ago
Martin Kroeker	bb9876db33	Fix thread races and infinite looping on systems with many cpus On systems with more than 64 cpus, blas_quickdivide will sometimes return zero which creates bogus workloads when used for the stride calculation. This then leads to threads spinning incessantly waiting for a status change that never happens, as seen in #1497. This patch also fixes several data races that were found by helgrind and/or tsan while debugging the issue.	7 years ago

Hank Anderson	e74462a3f5	Moved declarations to start of functions to satisfy MSVC C89 implementation.	10 years ago
Hank Anderson	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.	10 years ago
Timothy Gu	6c2ead30f0	Remove all trailing whitespace except lapack-netlib Signed-off-by: Timothy Gu <timothygu99@gmail.com>	11 years ago
Zhang Xianyi	5048a80032	Refs #283 . Fixed the incorrect usage of long data type for Windows 64.	12 years ago
Zhang Xianyi	32d2ca3035	Refs #214 , #221 , #246 . Fixed the getrf overflow bug on Windows. I used a smaller threshold since the stack size is 1MB on windows.	12 years ago
Zhang Xianyi	5d3312142a	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.	12 years ago
Zhang Xianyi	1b056c5328	Refs #130 Prevent reading ipiv array beyond the bound in ?laswp. Use laswp instead of laswp_oncopy in getrf.	13 years ago
Xianyi Zhang	342bbc3871	Import GotoBLAS2 1.13 BSD version codes.	14 years ago
