MAGMA
1.6.1
Matrix Algebra for GPU and Multicore Architectures
|
Driver and computational routines, and a few BLAS/auxiliary routines, currently return errors both as a return value and in the info argument.
The return value and info should always be identical. In general, the meaning is as given in this table. Predefined error codes are large negative numbers.
Info | Description |
---|---|
info = 0 (MAGMA_SUCCESS) | Successful exit |
info < 0, but small | For info = -i, the i-th argument had an illegal value |
info > 0 | Function-specific error such as singular matrix |
MAGMA_ERR_DEVICE_ALLOC | Could not allocate GPU device memory |
MAGMA_ERR_HOST_ALLOC | Could not allocate CPU host memory |
MAGMA_ERR_ILLEGAL_VALUE | An argument had an illegal value (deprecated; instead it should return -i to say the i-th argument was bad) |
MAGMA_ERR_INVALID_PTR | Can't free pointer |
MAGMA_ERR_NOT_IMPLEMENTED | Function or option not implemented |
MAGMA_ERR_NOT_SUPPORTED | Function or option not supported on the current architecture |
magma_xerbla is called to report errors (mostly bad arguments) to user.
magma_strerror returns string description of an error code.
