A deduplication pipeline method to enable shorter overall latency, servicing of multiple calls in parallel, and implementing higher data compression ratio. The method includes receiving user data for storage, performing deduplication operation on the data to obtain non-duplicative data, buffering the non-duplicative data in persistent memory, and accepting next user data for deduplication processing. In parallel to receiving the next user data, operating a co-processor to asynchronously compressing the data stored in the persistent memory and storing the compressed data in RAID.

Optimized pipeline to boost de-dup system performance

A resource use method, an electronic device, and a computer program product are provided in embodiments of the present disclosure. The method includes determining a plurality of jobs requesting to use accelerator resources to accelerate data processing. The plurality of jobs are initiated by at least one virtual machine. The method further includes allocating available accelerator resources to the plurality of jobs based on job types of the plurality of jobs. The method further includes causing the plurality of jobs to be executed using the allocated accelerator resources. With the embodiments of the present disclosure, accelerator resources can be dynamically allocated, thereby improving the overall performance of a system.

Allocation of accelerator resources based on job type

The present disclosure relates to a method, device and computer program product for executing a job in an application system. Here, the application system comprises a first processing device and a second processing device, and a first response speed of the first processing device being lower than a second response speed of the second processing device. In a method, a job request is received from a user of the application system, the job request specifying that the job is to be executed in the application system; a job type of the job is determined, the job type describing a requirement of the user on a response speed for executing the job; a target processing device is selected from the first processing device and the second processing device in accordance with determining that the job type relates to a high response speed; and the job is assigned to the selected target processing device, so that the job is executed by the target processing device. By means of the above method, a processing device for processing a job is selected based on the type of the job, and further processing devices in the application system may be dispatched more effectively. Furthermore, there is provided a corresponding device and computer program product.
