Resource Management Method and Corresponding Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 18590431 titled 'Resource Management Method and Corresponding Apparatus
The resource management method described in the patent application involves allocating address space identifiers (ASIDs) to processes running on different cores of a computer system, refreshing translation lookaside buffers (TLBs), and updating ASIDs in an iterative manner.
- ASIDs are allocated from a pool to processes running on a common core.
- A second ASID is allocated to a critical service process running on an isolated core.
- When the first ASIDs are exhausted, they are updated in an iteration manner.
- The TLB in the common core is refreshed to accommodate the updated ASIDs.
- The second ASID allocated to the isolated core is not updated, and its TLB does not need to be refreshed.
Potential Applications: - This method can be applied in multi-core computer systems to efficiently manage resources. - It can be useful in systems where critical services need to run on isolated cores for security or performance reasons.
Problems Solved: - Efficient allocation and management of ASIDs in a multi-core computer system. - Ensuring that critical services have dedicated resources for optimal performance.
Benefits: - Improved resource allocation and management in multi-core systems. - Enhanced performance and security for critical services running on isolated cores.
Commercial Applications: The technology can be valuable for companies developing high-performance computing systems, data centers, and other applications where resource management is crucial for optimal performance.
Questions about the technology: 1. How does the method described in the patent application improve resource management in multi-core computer systems? 2. What are the potential security implications of allocating a second ASID to a critical service running on an isolated core?
Original Abstract Submitted
A resource management method applied to a computer system includes allocating first address space identifiers (ASIDs) from an ASID resource pool to processes run by a common core of the computer system; allocating a second ASID to a process of a critical service run by an isolated core of the computer system, and when the first ASIDs are exhausted, updating the first ASIDs in an ASID generation iteration manner, and refreshing a translation lookaside buffer (TLB) in the common core such that when the first ASIDs are exhausted, the second ASID allocated to the isolated core is not updated, and the TLB in the isolated core does not need to be refreshed.
