Abstract

The invention relates to a method of improving the performance of Erlang virtual machines by a Xeon Phi coprocessor and applies to various Erlang-based applications. An Erlang virtual machine ERLVM_HOST is run in a host; an Erlang virtual machine ERLVM_PHI is run in a Xeon Phi compressor card. A thread management channel and a message transmission channel are created between two Erlang virtual machines, so that Erlang thread submission and transferring and message transmission between the Er virtual machines are realized, and a load balance mechanism of the Erlang virtual machines in the Xeon Phi coprocessor is modified. The method has the advantages that the host platform and the Xeon Phi coprocessor platform different from each other in structure are combined, the concurrency and performance of Erlang virtual machines are improved, and the Erlang virtual machines can bear higher throughput.

Description

technical field [0001] The present invention relates to a method through Xeon Phi TM ) method for improving the performance of the Erlang virtual machine by the coprocessor is suitable for improving the concurrency of various applications written in Erlang that require extremely high parallelism, thereby improving the operating performance of such applications. Applications in this category include web server programs, database management programs, key-value storage systems, real-time messaging systems, and high-performance computing programs. Background technique [0002] Erlang is a language for building large scalable soft real-time systems that require high availability. The Erlang virtual machine is a platform for running programs written in the Erlang language. Application programs written in the Erlang language are compiled into bytecodes and then run on the Erlang virtual machine. In the Erlang virtual machine, the basic unit of operation is a lightweight Erlang pr...
