Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In OpenCL environments, the inefficient mapping of read-only buffers into ordinary memory buffers leads to suboptimal performance due to the abandonment of more efficient data loading solutions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If read-only buffers are mapped into ordinary memory buffers, then the system can handle both read-only and read-write buffers uniformly, but data loading efficiency deteriorates due to abandonment of efficient fetching instructions
Solution Approach 1:
The patent segments the memory space into distinct read-only storage spaces and ordinary memory buffers. The compiler analyzes buffer access patterns and selectively maps read-only buffers to read-only storage spaces while mapping read-write buffers to ordinary memory buffers, thereby resolving the contradiction between uniform handling flexibility and optimized data loading efficiency
Solution Approach 2:
The patent applies local quality by providing different storage space characteristics for different buffer types. Read-only buffers receive specialized read-only storage spaces with efficient fetching instructions, while read-write buffers use ordinary memory buffers, allowing each buffer type to utilize the most appropriate storage characteristics for its specific access patterns
2Ease of manufacture
If the compiler uses ordinary memory buffer mapping for all buffers, then the implementation is simplified, but performance deteriorates by abandoning efficient fetching instructions for read-only buffers
Solution Approach 1:
The patent applies preliminary action by having the compiler perform static analysis during the compilation phase to identify read-only buffers and generate appropriate mapping instructions. This preliminary classification allows the system to automatically select optimal storage spaces without runtime complexity, maintaining implementation simplicity while achieving performance optimization
Solution Approach 2:
The patent changes the mapping parameter from a uniform ordinary memory buffer mapping to a differentiated mapping strategy based on buffer access characteristics. The compiler modifies the mapping behavior by detecting read-only qualifiers and adjusting the storage space selection accordingly, thereby improving performance without significantly complicating the implementation
3Productivity
If read-only buffers are identified and mapped to specialized storage spaces, then data loading efficiency is improved, but the system complexity increases due to additional analysis and mapping steps
Solution Approach 1:
The patent applies universality by designing a compiler analysis mechanism that handles both read-only and read-write buffers through a unified process. The same compiler infrastructure performs analysis and mapping for all buffers, automatically adapting the mapping strategy based on buffer characteristics, thereby limiting the increase in system complexity while achieving optimized data loading efficiency

AI summary
Disclosed are method and apparatus for loading task data, a computer device, a storage medium, and a computer program product. The method includes: analyzing various types of buffers involved in a task after the task is initiated, and determining whether each of the buffers satisfies a preset read-only buffer condition; determining a buffer satisfying the read-only buffer condition as a read-only buffer; mapping the read-only buffer into a matched read-only storage space based on space information of the read-only storage space and size information of the read-only buffer, and obtaining corresponding read-only mapping information; and loading task data in the read-only buffer into the matched read-only storage space based on the read-only mapping information. With the method, the loading efficiency of task data can be improved.
