A system according to one embodiment includes a collection of computing nodes arranged in a mesh of N&#xd7;M&#xd7;Z topology, the nodes including computational hardware, wherein Z&#x3c;N and Z&#x3c;M, and wherein N and M are at least equal to 4; a collection of I/O connections interfaced with one of the sides of the mesh, said side having N&#xd7;M nodes, each of the I/O connections being tied to a unique one of the nodes in said side; and I/O cards that are tied to the I/O connections.

Configuring computing nodes in a three-dimensional mesh topology

According to embodiments of the present disclosure, methods of and computer program products for operating a plurality of classifiers are provided. A plurality of input entities are read, each input entity having an associated target label. The input entities are provided to a first classifier, and a category of each input entity is obtained therefrom. A feature map is determined for each input entity. Each feature map is provided to each of a set of classifiers, and an assigned label is obtained for each feature map from each of the set of classifiers. Each classifier is associated with one of the categories. For each classifier, the assigned label for each feature map is compared to the target labels to determine a plurality of gradients. The plurality of gradients are masked according to each category, yielding a masked set of gradients for each category. Each classifier is trained according its associated masked gradients.

Variational gradient flow

A computer-implemented method is provided for use with a reconfigurable computational device having a collection of computing nodes arranged in a mesh of N&#xd7;M&#xd7;Z topology, the computing nodes including computational hardware, wherein Z&#x3c;N and Z&#x3c;M, and wherein N and M are at least equal to 4. The method includes using the computational device to perform computations characterized by (i) an initial system I/O bandwidth and (ii) an initial system node-to-node latency; reconfiguring the device into a mesh of N'&#xd7;M&#x2032;&#xd7;Z&#x2032; topology, wherein at least two of N, M, and Z values are different from their corresponding N&#x2032;, M&#x2032;, and Z&#x2032; values, and wherein N&#xd7;M&#xd7;Z is equal to N&#x2032;&#xd7;M&#x2032;&#xd7;Z&#x2032;; and using the device to perform computations characterized by (i) a modified system I/O bandwidth and (ii) a modified system node-to-node latency.
