## Support CPU & OS
Please read GotoBLAS_01Readme.txt
-Additional support CPU:
-x86_64:
- Intel Xeon 56xx (Westmere) //Used GotoBLAS2 Nehalem codes.
- Intel Sandy Bridge
-MIPS64:
- ICT Loongson 3A
- ICT Loongson 3B (Experimental)
+### Additional support CPU:
+
+#### x86/x86-64:
+* Intel Xeon 56xx (Westmere). Used GotoBLAS2 Nehalem codes.
+* Intel Sandy Bridge. Optimized Level-3 BLAS with AVX on x86-64.
+* AMD Bobcat. Used GotoBLAS2 Barcelona codes.
+#### MIPS64:
+* ICT Loongson 3A. Optimized Level-3 BLAS and the part of Level-1,2.
+* ICT Loongson 3B (Experimental)
## Usages
Link with libopenblas.a or -lopenblas for shared library.
### Set the number of threads with environment variables.
Examples:
+
export OPENBLAS_NUM_THREADS=4
or
### Set the number of threads with calling functions.
Examples:
+
void goto_set_num_threads(int num_threads);
+
void openblas_set_num_threads(int num_threads);
If you compile this lib with USE_OPENMP=1, you should use the above functions, too.
