Learning outcomes:
After successfully completing this module, students will be able to understand the operation of modern CPU/GPU structures and
to compare their essential characteristics. With the help of GPU programming paradigms, they will be able to plan massively parallel approaches to solutions,
assess their resource consumption and demonstrate their practicability on the basis of concrete implementations.
Furthermore, students will be able to adapt learned techniques to new problems and assess the quality of the corresponding solutions.

Module content:
The lecture will start with a short overview of the architecture and
basics of parallel programming for multi-core CPUs and GPUs.
In doing so, we will concentrate on the similarities and differences,
in order to simplify the programming of GPUs by transferring parallel programs
for multi-cores. In addition to techniques such as the regularization
of control flow and memory accesses, algorithmic
techniques will also be taught using several application domains
ranging from classical numerics to cryptography.
- The architecture of modern CPU cores
(super scalability, hyperthreading, etc.)
- The architecture of modern multi-core processors
(multiple cores, shared caches, memory access)
- The programming of modern multi-core processors
(basics of POSIX threads and OpenMP)
- Advanced programming of modern multi-core processors
(examples of coordination by critical sections, barriers, etc)
- The architecture of modern GPU architectures
(several multiprocessors, multiprocessors as SIMD architectures)
- Differences between GPUs and CPUs
(SIMD vs MIMD, data transport, CPU/GPU collaboration)
- Advantages of GPUs over CPUs
(processing power, explicit use of local memory, massive parallelism)
- Basics of GPU programming with CUDA
(example programs, time measurement, relation calculation transport)
- Differences between CUDA and OpenCL
(OpenCL more general, but more complex, code usually less efficient)
- Performance dependency between indexing and memory usage
(differences depending on dimensional number and size, placement of variables)
- Regularization of code for performance enhancement
(transfer of multi-core code to GPU, SIM, etc.)
- Numeric applications
(parallel numerical solution of simple differential equations)
- Combinatorial applications
(problems in graphs, focus on regularization)
- Cryptographic applications
(focus on regularity, as well as bit-serial implementation)
- Hard problems
(NP-hard problems, approximations, parallelization for GPU)
