Abstract

The invention discloses a method and a system for dispatching high-performance parallel applications on a cloud platform. The method comprises: setting a virtual machine type; acquiring network data packet information and spin lock information, and sending the information to a host machine; the host machine obtaining an information processing function according to a Hypercall call number, obtaining spin lock count and network data packet count, and according to the spin lock count, determining a single-node virtual machine synchronization demand, and according to the network data packet count, determining a span-node virtual machine synchronization request; according to the virtual machine type, the network data packet count, the spin lock count, and a synchronization request signal, determining a vCPU in a vCPU queue, the vCPU being called to operate next time. The system comprises a virtual machine information acquisition module, an information processing module, a virtual CPU dynamic allocation module, and a virtual CPU dispatching module. Through distinguishing a virtual machine of high-performance applications and a virtual machine of common applications, and making all related vCPU operate at the same time, the method solves a problem of frequent synchronization delay of high-performance calculation on a parallel application of a cloud platform.

Description

technical field [0001] The invention belongs to the technical field of cloud platform resource management and scheduling, and more specifically relates to a scheduling method and system for high-performance parallel applications on a cloud platform. Background technique [0002] Cloud computing improves the utilization of underlying hardware resources and computing costs, and has become an alternative to traditional clusters running high-performance computing. However, in a multi-virtual machine environment, virtualization technology causes the spin lock preemption problem to occur in the guest OS (guest Operation System); in a virtualization environment where multiple virtual machines compete for hardware resources, holding a spin lock The vCPU (virtual processor, virtual Central Processing Unit) of the virtual machine may be preempted by the vCPU of other virtual machines for CPU resources, so that the related vCPU waiting for the release of the spin lock is in a busy stat...
