/*
|
|
* First find your offload target, and if xnack is enabled/disabled using
|
|
|
|
rocminfo | grep amdgcn
|
|
|
|
* It should output a string like so:
|
|
|
|
"Name: amdgcn-amd-amdhsa--gfx942:sramecc+:xnack-"
|
|
|
|
* This lists the offload taret (gfx942) and that xnack is disabled (xnack-).
|
|
* Therefore, we need to specify --offload-arch=gfx942:xnack- to our link and compile commands.
|
|
* Please modify the compile and link commands to suit your system
|
|
|
|
* To compile:
|
|
hipcc -c -fgpu-rdc -x hip rocshmem_put_signal_test.cc \
|
|
--offload-arch=<target>:<xnack> \
|
|
-I/opt/rocm/include \
|
|
-I$ROCSHMEM_INSTALL_DIR/include \
|
|
-I$OPENMPI_UCX_INSTALL_DIR/include/
|
|
|
|
* To link:
|
|
hipcc -fgpu-rdc --hip-link rocshmem_put_signal_test.o -o rocshmem_put_signal_test \
