📄 Description

Fix NVSHMEM IBGDA duplicate-definition in host builds

Summary

This PR fixes a linker error that occurs when building the DeepEP Python extension with NVSHMEM enabled.

Problem

csrc/kernels/configs.cuh includes NVSHMEM’s internal header:

device_host_transport/nvshmem_common_ibgda.h

That header conditionally defines the global symbol:

nvshmemi_ibgda_device_state_d

When the header is included from a host-compiled translation unit (e.g. deep_ep.cpp built with g++), the symbol is emitted as a definition. Since DeepEP also links against libnvshmem_device.a, which defines the same symbol, the build fails at link time with:

multiple definition of `nvshmemi_ibgda_device_state_d`

This can be reproduced when building DeepEP against newer NVSHMEM releases (e.g. v3.5.19) in environments where configs.cuh is included by both CUDA (.cu) and host (.cpp) sources.

Solution

Restrict inclusion of nvshmem_common_ibgda.h to NVCC compilation contexts only:

#if defined(__CUDACC__)
#include <device_host_transport/nvshmem_common_ibgda.h>
#endif

This ensures:

  • The NVSHMEM IBGDA header is only included during CUDA compilation
  • Host-compiled translation units (e.g. deep_ep.cpp built with g++) do not emit
    a duplicate definition of nvshmemi_ibgda_device_state_d
  • The extension links cleanly when libnvshmem_device.a is present

Why this approach

When included from host-compiled code, nvshmem_common_ibgda.h can emit a
definition of nvshmemi_ibgda_device_state_d, which collides with the definition
provided by libnvshmem_device.a at link time.

Restricting the include to NVCC compilation avoids this duplicate-definition
path and makes the build more robust across NVSHMEM versions and build
environments.

The change is minimal and does not alter existing CUDA behavior.

Since DeepEP also links against libnvshmem_device.a, which defines the same symbol, the build fails at link time with: ``` multiple definition of `nvshmemi_ibgda_device_state_d` ``` This can be reproduced when building DeepEP against newer NVSHMEM releases (e.g. v3.5.19) in environments where configs.cuh is included by both CUDA (.cu) and host (.cpp) sources. ## Solution Restrict inclusion of nvshmem_common_ibgda.h to NVCC compilation contexts only: ``` #if defined(__CUDACC__) #include <device_host_transport/nvshmem_common_ibgda.h> #endif ``` This ensures: - The NVSHMEM IBGDA header is only included during CUDA compilation - Host-compiled translation units (e.g. deep_ep.cpp built with g++) do not emit a duplicate definition of nvshmemi_ibgda_device_state_d - The extension links cleanly when libnvshmem_device.a is present Why this approach When included from host-compiled code, nvshmem_common_ibgda.h can emit a definition of nvshmemi_ibgda_device_state_d, which collides with the definition provided by libnvshmem_device.a at link time. Restricting the include to NVCC compilation avoids this duplicate-definition path and makes the build more robust across NVSHMEM versions and build environments. The change is minimal and does not alter existing CUDA behavior. ## My build log hitting this ``` #38 15.06 Cloning into 'deepep'... #38 15.64 + cd deepep #38 15.64 + git fetch origin
