<title>Two papers accepted to ICS 2026</title>
<link>https://ku-csarch.github.io/post/accepted-ics26/</link>
<pubDate>Sat, 04 Apr 2026 00:00:00 +0000</pubDate>
<guid>https://ku-csarch.github.io/post/accepted-ics26/</guid>
<description><p>Two papers have been accepted to the <em>ACM International Conference on Supercomputing (ICS) 2026</em>. One paper proposed <em>SumcheckPIM</em>, an efficient HBM-based PIM architecture for sumcheck-based ZKPs. <em>SumcheckPIM</em> employs modular arithmetic units near banks and a Fiat-Shamir unit on a logic die. <em>SumcheckPIM</em> also introduces an efficient DRAM-aware folding mechanism to minimize bank conflicts in PIM operations. <em>SumcheckPIM</em> improves the performance of sumcheck protocols dramatically compared to GPU and CPU baselines. Another paper proposes <em>ACE</em>, an accuracy-aware compute engine for ternary LLM inferences. <em>ACE</em> integrates compact ternary decoding and scaling directly into the GEMM pipeline. An FPGA prototype of <em>ACE</em> demonstrates significant accuracy-aware efficiency gains compared to A100 and H100 baselines.</p>

<description><p>One paper was accepted to <em>IEEE Micro</em>. Our paper presents an accelerator architecture using logarithmic number systems, called <em>LogFlex</em>, which applies an adaptive log-domain quantization scheme based on data distributions to provide higher accuracy with low-precision quantized data formats. LogFlex enables near-FP16 accuracy while consuming 33% less energy than FP8-based accelerators.</p>

In order to implement efficient factorized and unfactorized dot-product computations, <em>FINEA</em> utilizes filter indexes derived from preprocessed weight tables.</p>

<description><p>One paper was accepted to <em>Journal of System Architecture</em>. Our paper presents an efficient prefetching approach for Transformer workload on GPU&rsquo;s unified virtual memory (UVM). Our analysis results reveal the default tree-based neighborhood prefetcher in UVM cannot handle the data locality over one virtual address block (VABlock). By extending the range of prefetching to multiple VABlocks, our proposed approach can improve the performance of Transformer workload when GPU memory is oversubscribed.</p>

<description><p>Two papers have been accepted for publication in <em>IEEE Access</em>. One paper proposes <em>GhostLeg</em>, a low-overhead architectural defense approach against correlation-based GPU security attacks. <em>GhostLeg</em> selectively applies secure executions for load warps to minimize performance overhead induced by concealing memory coalescing. Another paper presents detailed characteristics of GCN aggregation kernels on GPU via an in-depth analysis using real GPU hardware and a cycle-accurate GPU simulator.</p>
