In the thesis a new count expression of mesh fractal dimension is introduced, on the basis of it the storage and operation counts of directs solution methods, assembly global stiffness iterative methods and ebe iterative methods have been analyzed and compared, a conclusion has been obtained that the storage and operation counts of direct solution methods is the most, the storage counts of the ebe iterative methods is the least. estimating compute scale for ebe iterative methods at shuguang 2000 parallel computer, it is make out that compute scale is large in the extreme if make the most of the memory of every processor. by analyzing the parallel compute performance of 2d upend - step flow calculation, it is proved that ebe iterative methods can achieve upper speedup rations
本文還提出了一種網格分維新的計算公式，並基於網格分維對直接解法，組集總剛矩陣的迭代解法和基於ebe的迭代解法等三種方法的存儲量和計算量進行了分析和比較，得出了直接解法無論存儲量和計算量均最大，基於ebe迭代解法存儲量最小的結論；在曙光2000并行機上估計了基於ebe迭代解法的計算規模，說明只要充分利用各處理機的內存，可解問題的規模是非常巨大的；對二維倒臺階流并行計算進行了性能分析，表明基於ebe策略的迭代解法能獲得較高的加速比。
