hipfft* functions don't call associated cufft* functions about rocfft HOT 10 CLOSED

Yes and no. The HIP repo you point is the support list on HIP language runtime API level.
hipBlas and hipFFT have their own support list(We don't have a published page yet).
hipBlas issue should report on hipBlas page. I checked with my co-worker, the hipBlas should be able to build on NV platform.
Again, we hasn't address hipFFT/rocFFT build on NV platform. Will let you know ASAP.

Anyway, some suggestions to isolate your problems:

• try small cases only link to hipBlas or hipFFT lib

• check the symbols in *.so with nm or readelf

• manipulate RPATH

So to clarify, should both the hipBLAS and hipFFT packages have interface functions to cuBLAS AND cuFFT respectively as well as ROC conditionally?

from rocfft.

hipBLAS is a wrapper of cuBLAS on NV platform and rocBLAS on AMD platform. So if you run hipBLAS on NV platform, you should be able to go. If you run hipBLAS on AMD platform, there might be some functions not implemented yet.
Currently, hipFFT is the wrapper only for rocFFT. We could make hipFFT like hipBLAS, in which just a wrapper of cuFFT and rocFFT.

Ah! Okay. Would it be beneficial for me to make a little header file that conditionally #Defines the appropriate cuda functions according to this and modeled after [this] (https://github.com/ROCm-Developer-Tools/HIP/blob/master/include/hip/nvcc_detail/hip_runtime_api.h) or [this] (https://github.com/ROCmSoftwarePlatform/hipBLAS/blob/develop/library/src/nvcc_detail/hipblas.cpp)? Should that be in a new project called hipFFT?

I'm sorry for the misunderstanding. When I read the main HIP README I thought all of this had been done already and I could just immediately port my code.

hipFFT header + hipfy tool is one way for porting.
Conditional defined header file is another way, but it should not been called hipFFT.

One of the Cray/HPE folks just told me this was sitting. Sorry for the delay.

I’ll chase this up internally for you.

We are working on the marshalling hipFFT library, and it should be ready within a couple days.

What is the current status of this issue?

from rocfft.

@txomin13, the new hipFFT repo is opened at https://github.com/ROCmSoftwarePlatform/hipFFT.
The current status is:

• The new hipFFT hasn't been integrated into the whole ROCm release distribution yet(should be soon). Once it is in, the hipFFT header file in rocFFT repo will be deprecated.
• From the source build, the new hipFFT is ready to use with HIP-clang back-end on AMD GPU.
• From the source build, the new hipFFT is not ready to use with HIP-nvcc back-end on NV GPU with the latest hip-clang compiler(still working on it). However, it works with older ROCm 3.3 HIP-nvcc(http://repo.radeon.com/rocm/apt/3.3/pool/main/h/hip-nvcc/)

from rocfft.

These functions should be working in the new hipFFT repo, with the exception of the 64-bit plan functions.
