Query: CARGO : Context Augmented Critical Region Offload for Network-bound
  datacenter Workloads   Network bound applications, like a database server executing OLTP queries or
a caching server storing objects for a dynamic web applications, are essential
services that consumers and businesses use daily. These services run on a large
datacenters and are required to meet predefined Service Level Objectives (SLO),
or latency targets, with high probability. Thus, efficient datacenter
applications should optimize their execution in terms of power and performance.
However, to support large scale data storage, these workloads make heavy use of
pointer connected data structures (e.g., hash table, large fan-out tree, trie)
and exhibit poor instruction and memory level parallelism. Our experiments show
that due to long memory access latency, these workloads occupy processor
resources (e.g., ROB entries, RS buffers, LS queue entries etc.) for a
prolonged period of time that delay the processing of subsequent requests.
Delayed execution not only increases request processing latency, but also
severely effects an application throughput and power-efficiency. To overcome
this limitation, we present CARGO, a novel mechanism to overlap queuing latency
and request processing by executing select instructions on an application
critical path at the network interface card (NIC) while requests wait for
processor resources to become available. Our mechanism dynamically identifies
the critical instructions and includes the register state needed to compute the
long latency memory accesses. This context-augmented critical region is often
executed at the NIC well before execution begins at the core, effectively
prefetching the data ahead of time. Across a variety of interactive datacenter
applications, our proposal improves latency, throughput, and power efficiency
by 2.7X, 2.7X, and 1.5X, respectively, while incurring a modest amount storage
overhead.
