Despite their wide applicability, their computational complexity in a single PBS impedes widespread adoption. However, at the application level, there are enough number of independent PBSs to achieve high data-level parallelism, making them suitable for running on GPUs known for their high parallel computing capability. On contemporary GPUs, peak integer performance has steadily increased, and the sizes of L2 cache and shared memory have also grown rapidly since the Volta architecture. Prior attempts to accelerate PBS on GPUs have fallen short due to their outdated implementations that cannot leverage recent GPU advances. In this paper, we introduce a GPU implementation that supports the latest PBS algorithm and incorporates GPU-trend-aware optimizations. Our implementation achieves a 10.8× performance improvement over the state-of-the-art (SOTA) GPU implementations on RTX 4090 and even outperforms the SOTA ASIC implementation.","PeriodicalId":51248,"journal":{"name":"IEEE Computer Architecture Letters","volume":"23 2","pages":"207-210"},"PeriodicalIF":1.4,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10570278","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141532506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to shared infrastructure and multi-tenant environments, serverless applications have high security requirements. Traditional virtual machines and containers cannot fully meet the requirements of serverless applications. Therefore, lightweight virtual machine technology has emerged, which can reduce overhead and boot time while ensuring security. In this letter, we propose TeleVM, a lightweight virtual machine for RISC-V architecture. TeleVM can achieve strong isolation through the hypervisor extension of RISC-V. Compared with traditional virtual machines, TeleVM only implements a small number of IO devices and functions, which can effectively reduce memory overhead and boot time. We compared TeleVM and QEMU+KVM through experiments. Compared to QEMU+KVM, the boot time and memory overhead of TeleVM have decreased by 74% and 90% respectively. This work further improves the cloud computing software ecosystem of RISC-V architecture and promotes the use of RISC-V architecture in cloud computing scenarios.","PeriodicalId":51248,"journal":{"name":"IEEE Computer Architecture Letters","volume":"23 1","pages":"121-124"},"PeriodicalIF":2.3,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140830077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The critical components of a GAT model involve aggregation and attention, which cause numerous main-memory access. Recently, much research has proposed near-memory processing (NMP) architectures to accelerate aggregation. However, graph attention requires additional operations distinct from aggregation, making previous NMP architectures less suitable for supporting GAT. In this paper, we propose GATe, a practical and efficient \u0000<underline>GAT</u>\u0000 acc\u0000<underline>e</u>\u0000lerator with NMP architecture. To the best of our knowledge, this is the first time that accelerates both attention and aggregation computation on DIMM. In the attention and aggregation phases, we unify feature vector access to reduce repetitive memory accesses and refine the computation flow to reduce communication. Furthermore, we introduce a novel sharding method that enhances the data reusability. Experiments show that our work achieves substantial speedup of up to 6.77× and 2.46×, respectively, compared to state-of-the-art NMP works GNNear and GraNDe.","PeriodicalId":51248,"journal":{"name":"IEEE Computer Architecture Letters","volume":"23 1","pages":"87-90"},"PeriodicalIF":2.3,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140569407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
