Compute Abstraction是一个语句,指定了变量,变量间的算数操作,数据访存索引。对应于一条硬件计算内置函数。索引的范围应当在抽象中表示,假定我们有M个数据源,第m个数据源Srcm是Dm维向量。输出Dst是N维向量,输出数据的索引表示为i = [i1,i2,iN],第m维数据索引表示为jm=[jm1,jm2,jmDm],语句可以写为: ...

For this post I’m not interested in debating which approach is ‘best’. I’m not a fan of absolutes; there are simply problems and solutions. What is important is that either approach can work. What works for you might not work for another. Choose your poison. ...
In general, abstraction is implemented by what is generically termed an Application Programming Interface (API). API is a somewhat nebulous term that means different things in the context of various programming endeavours. Fundamentally, a programmer designs a set of functions and documents their inter...
