+# Notes on OpenBLAS usage
+## Usage
+
+#### Program is Terminated. Because you tried to allocate too many memory regions
+
+In OpenBLAS, we mange a pool of memory buffers and allocate the number of
+buffers as the following.
+```
+#define NUM_BUFFERS (MAX_CPU_NUMBER * 2)
+```
+This error indicates that the program exceeded the number of buffers.
+
+Please build OpenBLAS with larger `NUM_THREADS`. For example, `make
+NUM_THREADS=32` or `make NUM_THREADS=64`.  In `Makefile.system`, we will set
+`MAX_CPU_NUMBER=NUM_THREADS`.
+
+#### How can I use OpenBLAS in multi-threaded applications?
+
+If your application is already multi-threaded, it will conflict with OpenBLAS
+multi-threading. Thus, you must set OpenBLAS to use single thread in any of the
+following ways:
+
+* `export OPENBLAS_NUM_THREADS=1` in the environment variables.
+* Call `openblas_set_num_threads(1)` in the application on runtime.
+* Build OpenBLAS single thread version, e.g. `make USE_THREAD=0`
+
+If the application is parallelized by OpenMP, please use OpenBLAS built with
+`USE_OPENMP=1`
+
+#### How to choose TARGET manually at runtime when compiled with DYNAMIC_ARCH
+
+The environment variable which control the kernel selection is
+`OPENBLAS_CORETYPE` (see `driver/others/dynamic.c`) e.g. `export
+OPENBLAS_CORETYPE=Haswell` and the function `char* openblas_get_corename()`
+returns the used target.
+
+#### How could I disable OpenBLAS threading affinity on runtime?
+
+You can define the `OPENBLAS_MAIN_FREE` or `GOTOBLAS_MAIN_FREE` environment
+variable to disable threading affinity on runtime. For example, before the
+running,
+```
+export OPENBLAS_MAIN_FREE=1
+```
+
+Alternatively, you can disable affinity feature with enabling `NO_AFFINITY=1`
+in `Makefile.rule`.
+
+## Linking with the library
+
+* Link with shared library
+
+`gcc -o test test.c -I /your_path/OpenBLAS/include/ -L/your_path/OpenBLAS/lib -lopenblas`
+
+If the library is multithreaded, please add `-lpthread`. If the library
+contains LAPACK functions, please add `-lgfortran` or other Fortran libs.
+
+* Link with static library
+
+`gcc -o test test.c /your/path/libopenblas.a`
+
+You can download `test.c` from https://gist.github.com/xianyi/5780018
+
+On Linux, if OpenBLAS was compiled with threading support (`USE_THREAD=1` by
+default), custom programs statically linked against `libopenblas.a` should also
+link with the pthread library e.g.:
+
+```
+gcc -static -I/opt/OpenBLAS/include -L/opt/OpenBLAS/lib -o my_program my_program.c -lopenblas -lpthread
+```
+
+Failing to add the `-lpthread` flag will cause errors such as:
+
+```
+/opt/OpenBLAS/libopenblas.a(memory.o): In function `_touch_memory':
+memory.c:(.text+0x15): undefined reference to `pthread_mutex_lock'
+memory.c:(.text+0x41): undefined reference to `pthread_mutex_unlock'
+...
+```
+
+## Code examples
+
+#### Call CBLAS interface
+This example shows calling cblas_dgemm in C. https://gist.github.com/xianyi/6930656
+```
+#include <cblas.h>
+#include <stdio.h>
+
+void main()
+{
+  int i=0;
+  double A[6] = {1.0,2.0,1.0,-3.0,4.0,-1.0};
+  double B[6] = {1.0,2.0,1.0,-3.0,4.0,-1.0};
+  double C[9] = {.5,.5,.5,.5,.5,.5,.5,.5,.5};
+  cblas_dgemm(CblasColMajor, CblasNoTrans, CblasTrans,3,3,2,1,A, 3, B, 3,2,C,3);
+
+  for(i=0; i<9; i++)
+    printf("%lf ", C[i]);
+  printf("\n");
+}
+```
+`gcc -o test_cblas_open test_cblas_dgemm.c -I /your_path/OpenBLAS/include/ -L/your_path/OpenBLAS/lib -lopenblas -lpthread -lgfortran`
+
+#### Call BLAS Fortran interface
+
+This example shows calling dgemm Fortran interface in C. https://gist.github.com/xianyi/5780018
+
+```
+#include "stdio.h"
+#include "stdlib.h"
+#include "sys/time.h"
+#include "time.h"
+

+
+## Troubleshooting
+* Please read [Faq](https://github.com/xianyi/OpenBLAS/wiki/Faq) at first.
+* Please use gcc version 4.6 and above to compile Sandy Bridge AVX kernels on Linux/MingW/BSD.
+* Please use Clang version 3.1 and above to compile the library on Sandy Bridge microarchitecture. The Clang 3.0 will generate the wrong AVX binary code.
+* The number of CPUs/Cores should less than or equal to 256. On Linux x86_64(amd64), there is experimental support for up to 1024 CPUs/Cores and 128 numa nodes if you build the library with BIGNUMA=1.
+* OpenBLAS does not set processor affinity by default. On Linux, you can enable processor affinity by commenting the line NO_AFFINITY=1 in Makefile.rule. But this may cause [the conflict with R parallel](https://stat.ethz.ch/pipermail/r-sig-hpc/2012-April/001348.html).
+* On Loongson 3A. make test would be failed because of pthread_create error. The error code is EAGAIN. However, it will be OK when you run the same testcase on shell.
+
