Abstract: In order to provide a high-performance OGC-WPS( Open Geospatial Consortium,Web processing service) which supports high-concurrency of client requests,an extensible multi-process mode single WPS server is designed and implemented. On this basis,we build a scalable service cluster and implement an asynchronous processing mode based on thread pool and distributed cache.Experiments show that with this platform one can obtain good speed up and scalability in dealing with high concurrency tasks.
