I’m a senior researcher and lecturer in the SAFARI Research Group at ETH Zurich. I received BS and MS degrees in Telecommunication Engineering from the University of Sevilla, in 2001, and a PhD degree in Computer Science from the University of Córdoba, in 2012. Between 2005 and 2017, I was a faculty member of the University of Córdoba. My research interests focus on GPU and heterogeneous computing, processing-in-memory, memory systems, and hardware and software acceleration of medical imaging and bioinformatics. I am the lead author of PrIM, the first publicly-available benchmark suite for a real-world processing-in-memory architecture, and Chai, a benchmark suite for heterogeneous systems with CPU/GPU/FPGA.
I’m currently a leading collaborator in the EU project BioPIM.
Teaching
Courses 2023:
Seminar in Computer Architecture (Co-Lecturer)
Projects & Seminars: Data-Centric Architectures: Fundamentally Improving Performance and Energy (Main Lecturer)
Projects & Seminars: Programming Heterogeneous Computing Systems with GPUs (Main Lecturer)
PUMPS+AI summer school at Barcelona Supercomputing Center:
- Lecture 2: Input regularization
We covered two techniques that can be used to regularize input data for further computation. [Slides (pptx)]
These two techniques are also covered in our P&S HetSys course in the following two lectures:
Lecture 13: Parallel patterns: Merge | Lecture 14: Dynamic parallelism - Lecture 4: GPU implementation of neural networks
This lecture is an introduction to CNN, lowering convolutional layers to matrix multiplication, and advanced tiling (in shared memory and registers) for matrix multiplication [Slides (pptx)]
This lecture is also covered in our P&S HetSys:
Lecture 9: Advanced tiling for matrix multiplication - Lecture 6: Advanced features: Tensor cores, warp programming, unified memory.
This lecture covers advanced programming features such as tensor cores for ML/AI acceleration, warp programming for efficient inter-thread communication and synchronization, and unified memory for efficient and more programmable collaboration between CPU and GPU [Slides (pptx)]
These contents are covered in several P&S HetSys lectures:
Lecture 7: Parallel patterns: Histogram | Lecture 8: Parallel patterns: Convolution | Lecture 15: Collaborative computing
Courses 2022:
Seminar in Computer Architecture (Co-Lecturer)
Projects & Seminars: Data-Centric Architectures: Fundamentally Improving Performance and Energy (Main Lecturer)
Projects & Seminars: Programming Heterogeneous Computing Systems with GPUs (Main Lecturer)
