Abstract: In an aspect of the subject matter, a system dynamically selects a communication fabric for use with a trading exchange platform. The system includes a gateway executing on the trading exchange platform, and a client side library executing on a customer device that interacts with application programs executing on the customer device. The gateway and customer device communicate during an initial session over an out-of-band network to select a communication fabric (e.g., InfiniBand, etc.) of one or more communications fabrics available to the customer device. The client side library communicates with the gateway to establish a transaction session over an in-band network utilizing the selected communication fabric. The library then allows the customer device to perform transactions with the gateway of trading exchange platform through the gateway during the transaction session and over the in-band network utilizing the selected fabric.

Abstract: Write transactions with large amounts of data using a typical cache may consume over half of the available backing store bandwidth because of the way traditional caching algorithms fill lines during a write-invoked eviction. Relaxing the traditional constraint of cache coherency improves write performance by eliminating unneeded cache line fills. This technique conserves backing store bandwidth during many write operations while having negligible impact on the cache's read performance.
