rum time error in using MKL lapack function call

likehere — Mon, 13 Sep 2010 19:33:47 GMT

Hi,

Can anyone please provide some advice on how to deal with a run-time error from a lapack function (used to calculate eigen values). The codes can be compiled but I got the following run-time error:

MKL ERROR: Parameter 5 was incorrect on entry to DSYEV

Some background information:

1. I'm trying to use dsyev_ function for calculating eigenvalue/vectors by doing the following:

dsyev_("V","U", &n, &mat[0][0], &lda, &vec[0], work, &lwork, &info);

2. Environment is Linux and this is my LIB_DIRS:

LIB_DIRS = -L/xenv/ICC/X/11.0_081/mkl/lib/em64t /xenv/ICC/X/11.0_081/mkl/lib/em64t/libmkl_solver_ilp 64_sequential.a -Wl,--start-group /xenv/ICC/X/11.0_081/mkl/lib/em64t/libmkl_intel_ilp64.a /xenv/ICC/X /11.0_081/mkl/lib/em64t/libmkl_sequential.a /xenv/ICC/X/11.0_081/mkl/lib/em64t/libmkl_core.a -Wl,--end-group -lpthread -llapack

I have been struggling with this error for a long time, can someone please let me know what might be causing this?

Any information will be highly appreciated.

Thanks,

It is not possible to tell from the single line of code that you showed whether or not the parameters are correct, and why Parameter 5 is incorrect.

Please show the declarations of the subroutine arguments; in particular, what is the value of lda just before the call?

Vickie,

first of all please try to link witj lp64 libraries. in other words please try link with these

LIB_DIRS = -L/xenv/ICC/X/11.0_081/mkl/lib/em64t /xenv/ICC/X/11.0_081/mkl/lib/em64t/libmkl_solver_lp 64_sequential.a -Wl,--start-group /xenv/ICC/X/11.0_081/mkl/lib/em64t/libmkl_intel_lp64.a /xenv/ICC/X /11.0_081/mkl/lib/em64t/libmkl_sequential.a /xenv/ICC/X/11.0_081/mkl/lib/em64t/libmkl_core.a -Wl,--end-group -lpthread -llapack

and let us know will it works or not..
