However, the centralized metadata management in the distributed file system layer poses a scalability challenge. The object storage system has emerged as an alternative thanks to its simplified interface and scale-out architecture. Despite this, the HPC communities are used to working with the POSIX interface to organize their files into a global directory hierarchy and control access through access control lists.In this paper, we present ArkFS, a near-POSIX compliant and scalable distributed file system implemented on top of the object storage system. ArkFS achieves high scalability without any centralized metadata servers. Instead, ArkFS lets each client manage a portion of the file system metadata on a per-directory basis. ArkFS supports any distributed object storage system such as Ceph RADOS or S3-compatible system with an appropriate API translation module. Our experimental results indicate that ArkFS shows significant performance improvement under metadata-intensive workloads while showing near-linear scalability. We also demonstrate that ArkFS is suitable for handling the bursty I/O traffic coming from the burst buffer layer to archive cold data.","PeriodicalId":343684,"journal":{"name":"2023 IEEE International Parallel and Distributed Processing Symposium (IPDPS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126909430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By performing computations directly on the ciphertext (encrypted data) without decrypting it, FHE can guarantee the security of data throughout its lifecycle without compromising the privacy. However, the excruciatingly slow speed of FHE scheme makes adopting it impractical in real life applications. Therefore, hardware accelerators come to the rescue to mitigate the problem. Among various hardware platforms, FPGA clusters are particularly promising because of their flexibility and ready availability at many cloud providers such as FPGA-as-a-Service (FaaS). Hence, reusing the existing infrastructure can greatly facilitate the implementation of FHE on the cloud.In this paper, we present TurboHE, the first hardware accelerator for FHE operations based on an FPGA cluster. TurboHE aims to boost the performance of CKKS, one of the fastest FHE schemes which is most suitable to machine learning applications, by accelerating its computationally intensive and frequently used operation: relinearization. The proposed scalable architecture based on hardware partitioning can be easily configured to accommodate high acceleration requirements for relinearization with very large CKKS parameters. As a demonstration, an implementation, which supports 32,768 polynomial coefficients and a coefficient bitwidth of 594 decomposed into 11 Residue Number System (RNS) components, was deployed on a cluster consisting of 9 Xilinx VU13P FPGAs. The cluster operated at 200 MHz and achieved 1096 times throughput compared with a single threaded CPU implementation. Moreover, the low level hardware components implemented in this work such as the NTT module can also be applied to accelerate other lattice-based cryptography schemes.","PeriodicalId":343684,"journal":{"name":"2023 IEEE International Parallel and Distributed Processing Symposium (IPDPS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132871307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing literature of algorithms for TSP are neither adaptive to input data nor suitable for processing medium-size data on the modern classic and quantum machines. In this work, we leverage the classic computers’ power (large memory) and the quantum computers’ power (quantum parallelism), based on the input data, to fasten the hybrid algorithm’s overall running time. Our algorithmic ideas include trimming the input data efficiently using a classic algorithm, finding an optimal solution for the post-processed data using a quantum-only algorithm, and constructing an optimal solution for the untrimmed data input efficiently using a classic algorithm. We conduct experiments to compare our hybrid algorithm against the state-of-the-art classic and quantum algorithms on real data sets. The experimental results show that our solution truly outperforms the others and thus confirm our theoretical analysis.

For stateful applications, however, the use of serverless architectures is likely to lead to significant performance degradation, as frequent data sharing between different execution stages involves time-consuming remote storage access. Current platforms leverage memory cache to speed up remote access. However, conventional caching strategies show limited performance improvement. We experimentally find that the reason is that current strategies overlook the stage-dependent access patterns of stateful serverless applications, i.e., data that are read multiple times across stages (denoted as multi-read data) are wrongly evicted by data that are read only once (denoted as read-once data), causing a high cache miss ratio.Accordingly, we propose a new caching strategy, Duo, whose design principle is to cache multi-read data as long as possible. Specifically, Duo contains a large cache list and a small cache list, which act as Leader list and Wingman list, respectively. Leader list ignores the data that is read for the first time to prevent itself from being polluted by massive read-once data at each stage. Wingman list inspects the data that are ignored or evicted by Leader list, and pre-fetches the data that will probably be read again based on the observation that multi-read data usually appear periodically in groups. Compared to the state-of-the-art works, Duo improves hit ratio by 1.1×-2.1× and reduces the data sharing overhead by 25%-62%.","PeriodicalId":343684,"journal":{"name":"2023 IEEE International Parallel and Distributed Processing Symposium (IPDPS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127778306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing schemes that use GPU-aware MPI libraries are highly prone to saturating the interconnect bandwidth. Therefore, integrating GPU-based compression into MPI libraries has proven efficient to achieve faster training time. In this paper, we propose an optimized Ring algorithm of Allgather and Reduce-Scatter collectives that encompass an efficient collective-level online compression scheme. At the microbenchmark level, Allgather achieves benefits of up to 83.6% and 30.3% compared to the baseline and existing point-to-point-based compression in a state-of-the-art MPI library on modern GPU clusters. Reduce-Scatter achieves 88.1% and 40.6% compared to baseline and point-to-point compression, respectively.

Each stage of a GNN requires an aggregation (sparse matrix-matrix multiplication) and a linear operation (dense matrix-matrix multiplication). Numerous efforts have addressed the development of distributed implementations for GNNs. Although efficient algorithms for distributed matrix multiplication are well known, the challenge here is the collective optimization of sequences of distributed matrix-matrix multiplications required for GNN, where many degrees of freedom also exist in the ordering of the component matrix-multiplication operations.This paper develops a new approach to distributed GNN, ReDistribution of Matrices (RDM), centered around communication-free distributed matrix-multiplication enabled by matrix redistribution between GNN stages. While the approach is applicable to the numerous algorithmic variants of GNN, the experimental evaluation focuses on GCN (Graph Convolutional Network), including both full-batch training as well as sampling-based training using GraphSAINT. Experimental evaluation with 2-layer and 3-layer GCN, using 128 or 256 hidden features, across eight sparse datasets, on a multi-GPU system with 8 GPUs shows that RDM attains a geometric mean speedup between 2× and 3.7× over two state-of-the-art multi-GPU GCN implementations, CAGNET and DGCL.","PeriodicalId":343684,"journal":{"name":"2023 IEEE International Parallel and Distributed Processing Symposium (IPDPS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129667002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing SpMV optimization techniques typically focus on a single SpMV invocation and do not consider opportunities for optimization across a sequence of SpMV operations (SSpMV), leaving much room for performance improvement.

Unfortunately, existing learned policies are optimized with a few fixed cache sizes while in reality, cache sizes often vary over time in an unpredictable manner. As a result, existing solutions cannot provide consistent benefits in production settings.We present SLAP, a learned CDN cache admission approach based on segmented object reuse time prediction. SLAP predicts an object’s reuse time range using the Long-Short-Term-Memory model and admits objects that will be reused (before eviction) given the current cache size. SLAP separates model training from cache size, allowing it to adapt to arbitrary sizes. The key to our solution is a novel segmented labeling scheme that enables SLAP to precisely predict object reuse time. To further make SLAP a practical and efficient solution, we propose aggressive reusing of computation and training on sampled traces to optimize model training, and a specialized predictor architecture that overlaps prediction computation with miss object fetching to optimize model inference. Our experiments with production CDN traces show that SLAP achieves significantly lower write traffic (38%-59%), longer SSDs service life (104%-178%), a consistently higher hit rate (3.2%-11.7%), and requires no effort to adapt to changing cache sizes, outperforming existing policies.","PeriodicalId":343684,"journal":{"name":"2023 IEEE International Parallel and Distributed Processing Symposium (IPDPS)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116014884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
