Missing cusolver 64bit routines

Accelerated Computing GPU-Accelerated Libraries

In the cusolver documentation, I see “legacy” routines like cusolverDnDsytrd and cusolverDnDormtr. But, they aren’t mentioned in the 64bit routines documentation. Is there a way to access those 64bit versions directly? I don’t want to use cusolverDnXsyevd because there are some steps I need to do in my algorithm between the householder reduction and the backtransformation.

Hi Jeremiah,

64-bit APIs of SYTRD and ORMTR are not yet available. The existing legacy APIs for SYTRD and ORMTR will be available at least until the corresponding 64-bit APIs have been added. Please let me know if you encounter any issues using the legacy APIs.

Thanks,

Christoph

That’s good to hear. One benefit to the 64bit routines is that the user-supplied buffers (workspaces) are in a format that the rest of my code already uses.
