`fpga_hls_hw_emu` fails in `vpl` step #168

Open j-stephan opened 2 years ago

j-stephan commented 2 years ago

I'm on the current sycl/unified/next branch and using Vitis 2020.2 with a xilinx_u200_xdma_201830_2 target. Compiling the single_task_vector_add test case works fine but it fails once vpl is called:

$ clang++ --gcc-toolchain=/trinity/shared/pkg/compiler/gcc/11.2.0 -std=c++20 -fsycl -fsycl-targets=fpga64_hls_hw_emu single_task_vector_add.cpp

Okay, after diving into the log files produced by setting SYCL_VXX_KEEP_CLUTTER I was able to figure out that Vivado's own g++ executable is unable to find the correct path to its corresponding cc1plus. It simply wants to call cc1plus which isn't in my path. In my case it is located in /path/to/Vivado/2020.2/tps/lnx64/gcc-6.2.0/libexec/gcc/x86_64-pc-linux-gnu/6.2.0/. Adding this to my PATH lets the compile.sh script proceed. It feels a bit weird though that g++ is unable to deduce this by itself. Is this the right way to work around the problem?

lforg37 commented 2 years ago

We usually (try to) run the tests only with the most recent available vitis version (that would be 2021.2 as of now). Can you try with it (that requires only 300 GB of disk space 😅) ?

If not, I can try to reproduce the bug and investigate it, but that will probably not be possible before in 3-4 weeks.

j-stephan commented 2 years ago

Okay, it appears that the Vitis tools are unhappy if I have another GCC compiler toolchain in PATH and LD_LIBRARY_PATH. So my workflow currently looks like this:

  1. Load a modern GCC compiler to enable clang compilation.
  2. Enable SYCL_VXX_KEEP_CLUTTER.
  3. Use clang to compile the test case.
  4. Wait until it crashes in the sycl-link-vxx step.
  5. Unload the modern GCC version.
  6. Navigate to the temporary directory mentioned in the log output and rerun the command found in <tempdir>/07-vxxlink.cmd.
lforg37 commented 2 years ago

Ok we can try to reproduce these steps with our install to see if this bug still exists in recent vitis version.

j-stephan commented 2 years ago

Thanks! And I'll see what can be done about a more recent software stack. It also turned out that the node itself is still utilizing XRT 2019.1 which doesn't work well with more recent Vitis versions...

keryell commented 2 years ago

Try to use the most modern version of everything. :-)

keryell commented 2 years ago

We do not use the Vitis/Vivado setup because it breaks too many things, we just use the recipe from https://github.com/triSYCL/sycl/blob/sycl/unified/next/sycl/doc/GettingStartedXilinxFPGA.md#compiling-and-running-a-sycl-application Are you using a similar setup?

j-stephan commented 2 years ago

So far I relied on the module system of the cluster to set up everything for me. I have now created a script that bypasses the module system for the Xilinx tools which looks very similar to the environment setup in the link. The results stays the same, though; vpl will fail in the config_hw_emu.compile step. When diving into the details /tmp/<build dir>/vxx_link_tmp/link/vivado/vpl/prj/prj.sim/sim_1/behav_waveform/xsim/compile.sh will fail with the following error message:

g++: error trying to exec 'cc1plus': execvp: No such file or directory

This error message goes away once I unload the gcc-11 module (which removes the entire gcc toolchain from PATH and LD_LIBRARY_PATH). Afterwards I can call the command from /tmp/<build dir>/07-vxxlink.cmd and it will happily continue (until the node's ancient xclbinutil complains about unknown parameters - I hope my IT department will resolve this soon).

j-stephan commented 2 years ago

IT installed Vitis 2021.2 on the cluster. The issue persists, though - if I load the gcc-11 module the Vitis tools will fail to detect their own cc1plus. My current work-around looks like this:

$ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/trinity/shared/pkg/compiler/gcc/11.2.0/lib64 $SYCL_BIN_DIR/clang++ --gcc-toolchain=/trinity/shared/pkg/compiler/gcc/11.2.0 -std=c++20 -fsycl -fsycl-targets=fpga64_hls_hw_emu single_task_vector_add.cpp

This lets the HLS flow continue until xclbinutil is called.
