LAPACKE_cheevx equivalent function in oneMKL DPC++ for GPU

[TestDR]

Hi,

Could you please advise when LAPACKE_cheevx equivalent function can be included in oneMKL DPC++ for GPU?

Thanks for posting in Intel communities.

Could you please let us know if any of the following routines would satisfy your requirements.

1. heevd
2. heevs(USM Version)

Thanks and Regards,

Hi,

Thanks for your reply. Cheevx calculate selected number of eigen values whereas heevd calculate them all. We are developing a time sensitive application and we want something like cheevx. When can we expect something like cheevx with GPU support?

Thanks,

Hi Rajitha, 

This is to kindly inform you that, there is no exact date when heevx would be available with GPU support. We will inform you as soon as we have an update. As of now, heevd is the only alternative available. Kindly let us know if we could close this case on our end.

Thanks and Regards,

We may evaluate “heevd” for calculating all the eigen values. However, I could not find an example for “heevd” within /opt/intel/oneapi/mkl/2023.0.0/examples/examples_dpcpp.tgz. Can you please point me to an example?  My aim is to see whether it is profitable to offload heevd computation into a GPU using Intel Advisor.
