Large scale geostatistics with locally varying anisotropy 

Peredo Andrade, Oscar Francisco (Date of defense: 2022-06-09)

Classical geostatistical methods are based on the hypothesis of stationarity, which allows to apply repetitive sampling in different locations of the spatial domain, in order to obtain enough information to infer cumulative ...

Autonomous and reliable operation of multilayer optical networks 

Barzegar, Sima (Date of defense: 2022-06-03)

This Ph.D. thesis focuses on the reliable autonomous operation of multilayer optical networks. The first objective focuses on the reliability of the optical network and proposes methods for health analysis related to ...

On the co-design of scientific applications and long vector architectures 

Gómez Crespo, Constantino (Date of defense: 2022-05-23)

The landscape of High Performance Computing (HPC) system architectures keeps expanding with new technologies and increased complexity. To improve the efficiency of next-generation compute devices, architects are looking ...

Exploiting data locality in cache-coherent NUMA systems 

Sánchez Barrera, Isaac (Date of defense: 2022-04-06)

The end of Dennard scaling has caused a stagnation of the clock frequency in computers.To overcome this issue, in the last two decades vendors have been integrating larger numbers of processing elements in the systems, ...

Adaptable register file organization for vector processors 

Ramírez Lazo, Cristóbal (Date of defense: 2022-04-04)

Today there are two main vector processors design trends. On the one hand, we have vector processors designed for long vectors lengths such as the SX-Aurora TSUBASA which implements vector lengths of 256 elements (16384-bits). ...
