HPP_UIUC_MP2: basic matrix multiplication-----BlockDIM!

这次作业有个地方搞的我输出的C矩阵一直都是全000000.

然后发现原来是DimBlock设置的太大了。

//@@ Initialize the grid and block dimensions here
    dim3 DimBlock(8, 8, 1); // if the threads each block is too large, say
			    // 32, then the C output will be all 000000000
	                    // so fail!!!!
    dim3 DimGrid((numCColumns - 1) / DimBlock.x + 1,
                 (numCRows - 1) / DimBlock.y + 1, 1);

这样就可以得到正确结果了。
