Abstract: Communication-optimal algorithms are known for square matrix multiplication. Here, we obtain the first communication-optimal algorithm for all dimensions of rectangular matrices. Combining ...

Abstract: While many approaches have been proposed to analyze the problem of matrix multiplication parallel computing, few of them address the problem on heterogeneous networks. It still remains an ...

PSA: There’s officially a new bag shape on the block and it sure does know its angles. It’s time to say bye bye to the baguette and ditch your curved crossbody, as this season our arm candy’s turning ...

A TikTok video of a novel, ancient multiplication method has gone viral. While the user, jesslouisec, calls the method Japanese multiplication and some mathematicians say it’s “Vedic multiplying,” its ...

Computer scientists have discovered a new way to multiply large matrices faster than ever before by eliminating a previously unknown inefficiency, reports Quanta Magazine. This could eventually ...

Computer scientists are a demanding bunch. For them, it’s not enough to get the right answer to a problem — the goal, almost always, is to get the answer as efficiently as possible. Take the act of ...
