Faster big-data analysis

System for performing “tensor algebra” offers 100-fold speedups over previous software packages. [caption id="attachment_13488" align="alignnone" width="639"] A new MIT computer system speeds computations involving “sparse tensors,” multidimensional data arrays that consist mostly of zeroes.Image: Christine…

Selective memory

Scheme would make new high-capacity data caches 33 to 50 percent more efficient. CAMBRIDGE, Mass. -- In a traditional computer, a microprocessor is mounted on a “package,” a small circuit board with a grid of…
