DATA PROCESSING PERFORMANCE ENHANCEMENT IN A DISTRIBUTED FILE SYSTEM
First Claim
1. A method for enhancing performance for data processing in a distributed file system, the method, comprising:
- invoking operating system calls to optimize cache management by an I/O component;
wherein, the operating system calls are invoked to perform one or more of;
proactive triggering of readaheads for sequential read requests of a disk;
purging data out of buffer cache after writing to the disk or performing sequential reads from the desk;
eliminating a delay between when a write is performed and when written data from the write is flushed to the disk from the buffer cache.

Abstract
Systems and methods of data processing performance enhancement are disclosed. One embodiment includes, invoking operating system calls to optimize cache management by an I/O component; wherein, the operating system calls are invoked to perform one or more of proactive triggering of readaheads for sequential read requests of a disk; purging data out of buffer cache after writing to the disk or performing sequential reads from the desk; and/or eliminating a delay between when a write is performed and when written data from the write is flushed to the disk from the buffer cache.

19. A system for enhancing performance for data processing in a distributed file system, the system, comprising:
-
means for, invoking operating system calls to optimize cache management by an I/O component of the operating system for reads and writes in MapReduce; means for, decreasing checksum overhead in speeding up the distributed file system read path to enhance performance of the distributed file system; means for, optimizing the distributed file system (DFS) for random read performance. - View Dependent Claims (20, 21, 22)

23. A system for distributed computing, the system, comprising:
-
a set of machines forming a distributed file system cluster, a given machine in the set of machines having; a processor; a disk; memory having stored there on instructions which when executed by the processor, causes; readaheads for sequential read requests of the disk to be proactively triggered; data to be purged out of buffer cache after writing to the disk or performing sequential reads from the desk. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
