Description

The xerbla function is an error handler for Intel® oneAPI Math Kernel Library BLAS, LAPACK, Vector Math, and Vector Statistics functions. These functions call xerbla if an issue is encountered on entry or during the function execution.

xerbla operates as follows:

Prints a message that depends on the value of the info parameter as explained in the following table.

NOTE:

A specific message can differ from the listed messages in numeric values and/or function names.
Returns to the calling application.

Error Messages Printed by xerbla
Value of info	Error Message
1001	`Intel MKL ERROR: Incompatible optional parameters on entry to DGEMM.`
1000 or 1089	`Intel MKL INTERNAL ERROR: Insufficient workspace available in function CGELSD.`
< 0	`Intel MKL INTERNAL ERROR: Condition 1 detected in function DLASD8.`
Other	`The position of the invalid parameter in the parameter list of the calling function.`

Note that xerbla is an internal function. You can change or disable printing of an error message by providing your own xerbla function. The following examples illustrate usage of xerbla.

Example

subroutine xerbla (srname, info)
character*(*) srname  !Name of subprogram that called xerbla
integer	info	!Position of the invalid parameter in the parameter list
return	!Return to the calling subprogram end
end
