一种基于多核CPU加速DLIS测井数据解码方法

A DLIS Logging Data Decoding Method Accelerated by Multi-core CPU

为了解决现有的DLIS数据导出软件对于大DLIS文件解码效率低的问题,提出基于目前普遍使用的多核CPU处理器,根据DLIS测井数据文件的内部逻辑结构重新构建DLIS内部测井曲线信息结构,在北基础上设计并行算法来加速DLIS测井数据解码的方法。将该方法应用到多个同样结构不同大小的DLIS文件,结果表明,该方法能够加快DLIS的解码速度,与原来的串行解码方法相比获得较好的加速比。

In order to improve the decoding of large DLIS files,a multi-core CPU-based method is proposed.It first reconstructs the internal information structure of a DLIS logs based on the internal logical structure of a DLIS logging file,then designs a parallel algorithm to accelerate decoding DLIS logging data.The method has been applied to many DLIS files with the same structure and different sizes,and has been proved that it can accelerate decoding and the speedup is better than a serial program.
