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 #821 in the
exaloop/codonrepository fixed an invalid behavior when using an ordereddictin GPU round-trip usage, addressing a segmentation fault that occurred during the conversion ofdict[int, List[float]]from host to device and back. The solution involved modifying the handling of device pointers for ordered dictionaries. -
Opened pull request #819 aims to fix a limited global variable initialization problem in the Codon compiler by updating the constant propagation pass to accept global constants initialized through scalar cast patterns. This change is intended to enhance the handling of global constants beyond just literal values.
-
Reported issue #818 describes a problem where the complex
sinoperation results innanvalues, which appears to be related to uninitialized global variables. A minimal reproducible example was provided to illustrate the issue. -
Merged pull request #804 implemented the
f16extension in the GPU module, enabling operations withfloat16types. The implementation included a test suite to ensure proper functionality, demonstrating successful execution of a sample kernel. -
Engaged in discussions on various issues and pull requests, including clarifications on JIT symbol mapping improvements and the implications of changes made in pull request #802, which aimed to mitigate symbol pollution during JIT compilation.
