Hi, I'm Sung-Woo Choi from South Korea.
I'm a Computer Science student at UNIST.

I'm interested in compilers, systems, and GPUs.
My work focuses on LLVM-based analysis, low-level performance, and correctness issues in systems software.

• Merged pull request #835 in the exaloop/codon repository added bfloat16 compiler runtime conversion helper symbols to CMakeLists.txt, addressing issue #834. This change ensures that the bf16 conversion helpers are default-visible before linking into libcodonrt.so.

• Merged pull request #830 updated the NVPTX optimization pipeline to apply GPU optimization passes (gpuopt1 and gpuopt2) to the prepared GPU module instead of the host module, resolving issue #829.

• Merged pull request #828 implemented a patch in gpu.cpp to handle cases where no concrete GPU kernels are realized, fixing issue #827 by ensuring no GPU module is created and no PTX blob is emitted when no definitions exist.

• Opened issue #834 raised concerns about linking failures for GPU kernels using bfloat16 scalar operations due to missing compiler runtime conversion helper symbols.

• Opened issue #829 highlighted that GPU optimization passes were incorrectly applied to the host module instead of the GPU module, potentially leaving GPU-only helper functions unoptimized.

• Opened pull request #826 proposed a Python GPU DSL decorator implementation, which includes GPU-specific source rewriting and a dedicated callback path for launch metadata.
