Xianyi Zhang 5be22ca80d Refs #72. Upgraded LAPACK to 3.4.0 version. 2011-11-28 15:28:22 +08:00
traits 19f5b5c132 Fixed #66 the bug in zgemv kernel with transpose matrix on 64-bit MingW (Windows). 2011-10-18 18:44:23 +08:00
traits c852ce3981 Ref #65. Fixed 64-bit Windows calling convention bug in cdot and zdot. 
According to 64-bit Windows calling convention, the return value is in %rax instead of %xmm0 in cdot kernel.
In zdot, the caller allocates a memory space for return value and sets this memory address to the first hidden parameter. Thus, the callee (zdot) should assign the result to this memory space and return the memory address in %rax.

Xianyi Zhang ba31b19c00 Ref #62. In OpenMP implementation, check the return value of omp_get_max_threads(). 
It makes sure the return value as same as blas_cpu_numbers which is an internal global variable to store the number of threads in OpenBLAS.

traits 66a3c6df4e Ref #63. Fixed generating DLL bug on ming-w64. 2011-10-09 17:25:44 +08:00
Xianyi Zhang 57658a8c14 ref #62. Added the user friendly message with USE_OPENMP=1. The users should use OMP_NUM_THREADS. 
When OpenBLAS is compiled with USE_OPENMP=1, it ignores OPENBLAS_NUM_THREADS and GOTO_NUM_THREADS flags.Therefore, you should use OMP_NUM_THREADS.

Without setting OMP_NUM_THREADS, a process will use maximal number of threads on a computing node. Thus, if there are 2 processes on the computing node, the thread will contend against other threads on CPU cores. As a result, the application will hang.

Xianyi bcc7956216 Refs #57. Continue to fix absolute path issue about shared library on Mac OSX. 
Used $(CURDIR) instead of pwd in generating shared library on Mac OSX.
Add more tips about this issue. Thank Dr Kane O'Donnell.

Xianyi 68cae521df Refs #57. The bug about absolute path of shared library on Mac OSX. 
OSX cann't use relative path in shared library. Thank Mr.Kane for this patch. The detail is in this link (https://github.com/xianyi/OpenBLAS/issues/57).

Xianyi d0152ec8ca Fixed #61 a building bug about setting TARGET and DYNAMIC_ARCH at the same time. 2011-09-17 02:27:56 +08:00
Zhang Xiianyi 7b410b7f0e Fixed #58 zdot SEGFAULT bug with GCC-4.6. Thank Mr. John for this patch. 
In i386 calling convention, the caller put the address of return value of zdot into the first hidden parameter.
Thus, the callee should delete this address before return.
Actually, I have fixed the same bug on x86/zdot_sse2.S (issue #32). However, that is not a good implementation which uses 3 instructions. Mr. John told me used "ret $0x4" to skip the first hidden address (4 bytes).
