A composite adsorbent for separating ethylbenzene from C8 arene by an adsorption distillation contains 1-50 mass % of a xylene adsorbent and 50-99 mass % of a carrier liquid. The carrier liquid is selected from one or two of alkane, aryl-substituted alkane, decalin and alkyl-substituted decalin. The alkane is C10-C26 alkane, and the aryl-substituted alkane is C13-C16 aryl-substituted alkane. The composite adsorbent can increase the volatility of ethylbenzene relative to other C8 arenes and thus can separate a high-purity ethylbenzene from C8 arene by the adsorption distillation.

Decoupled computing systems include layers of same-type computing resources, and include a dispatch layer to assign tasks from one layer to another, such as input and output (I/O) flows. The I/O flows can be assigned to particular computing resources of a layer based on a weighted moving average of performance data for the layer. When traffic is high, the assignment can include random assignment to some or all of the computing resources in the layer. The I/O flows can be split between read-intensive and write-intensive flows, with more read-intensive flows being assigned based on a pick ratio.

Systems and methods for input/output dispatch

Systems and methods are provided for improved point querying of a database. The index values are separated from data and retained in cache memory to allow access without requiring a disk input/output (I/O) operation and thereby having less latency resulting from such disk I/O operations. The index values can be compressed using an algorithm such as Crit-Bit-Trie to allow storage of the index values in limited cache memory space. The index values can be selected for storage according to a least recently used approach when cache memory is insufficient to store all index values to maintain a hit rate for the cached portion and reduce the disk I/O operations.
