Modern datacenter applications demand high throughput (40Gbps) and ultra-low latency (< 10 &#956;s per hop) from the network, with low CPU overhead. Standard TCP/IP stacks cannot meet these requirements, but Remote Direct Memory Access (RDMA) can. On IP-routed datacenter networks, RDMA is deployed using RoCEv2 protocol, which relies on Priority-based Flow(More)
Computing environments become increasingly parallel, and it seems likely that we will see more cores on tomorrow's desktops and server platforms. In a highly parallel system, tracing garbage collectors may not scale well due to deep heap structures that hinder parallel tracing. Previous work has discovered vulnerabilities within standard Java benchmarks. In(More)
Direct network I/O allows network controllers (NICs) to expose multiple instances of themselves, to be used by untrusted software without a trusted intermediary. Direct I/O thus frees researchers from legacy software, fueling studies that innovate in multitenant setups. Such studies, however, overwhelmingly ignore one serious problem: direct memory accesses(More)
Apache is a large-scale industrial multi-process and multi-threaded application, which uses lock-based synchronization. We report on our experience in modifying Apache to employ transactional memory instead of locks, a process we refer to as transactification; we are not aware of any previous efforts to transactify legacy software of such a large scale.(More)
VLSI chips design is becoming increasingly complex and calling for more and more automation. Many chip design problems can be formulated naturally as constraint problems and are potentially amenable to CP techniques. To the best of our knowledge, though, there has been little CP work in this domain to date. We describe a successful application of a CP based(More)
