8.ChangeLog
Please see Changelog.txt to obtain the differences between GotoBLAS2 1.13 BSD version.
9.Known Issues
* The number of CPUs/Cores should less than or equal to 8*sizeof(unsigned long). On 64 bits, the limit
is 64. On 32 bits, it is 32.
* 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. I don't think this is a bug in OpenBLAS.
9.Troubleshooting
* 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 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.
