Jack Márquez is a Computer Engineer and a specialist in computer security. He is currently pursuing his PhD in engineering at the Universidad Autónoma de Occidente de Santiago de Cali in Colombia. He joined the BISITE group to complete his doctoral thesis and will stay with us until the end of May, by which time he hopes to have completed his research.

Jack is working on the final part of his thesis, which involves improving the performance of heterogeneous storage systems in HPC Cloud systems using efficient storage algorithms that are supported by statistical models.

The migration of scientific applications or HPC (High Performance Computing) to Cloud Computing environments is becoming more frequent. However, such migration encounters several difficulties; due to the overhead caused by the virtualization of resources, HPC applications experience a reduction in their performance, file systems and communication technologies, among others. 

To address this problem, Jack is developing a statistical model based on Extreme Value Theory (EVT) that allows to predict the performance of HPC applications that use heterogeneous Cloud Computing storage systems. The model then provides the efficient storage algorithm with these predictions, the algorithm is in charge of deciding in which type of storage device (from those available in the Cloud) to store the data, aiming to reduce the overhead caused by virtualization.

At our group, we work on projects that involve the use of a wide range of technologies. I hope that your stay at BISITE will give you the knowledge you need to successfully complete your research.
