RDMA (Remote Direct Memory Access) Programming

1. Direct memory access: Allows data transfer between computers' memory without involving the CPU, reducing latency and CPU overhead.
2. Kernel bypass: Applications bypass the operating system's kernel for data transfer, enhancing performance by avoiding context switches.
3. Asynchronous operations: Supports asynchronous data transfer, enabling applications to continue processing while data is transferred over the network.
4. Remote memory access: Enables applications to read from and write to memory on remote machines efficiently.

Before learning RDMA programming, it's beneficial to have the following skills:

1. Network programming: Understanding of network protocols, socket programming, and network architectures is essential for working with RDMA.
2. Memory management: Knowledge of memory allocation, deallocation, and memory access techniques is crucial for RDMA programming.
3. Operating system concepts: Familiarity with operating system concepts such as processes, threads, and memory management helps in understanding RDMA's interaction with the operating system.
4. Distributed systems: Understanding of distributed systems principles, including communication models, consistency, and fault tolerance, is helpful for designing and implementing RDMA-based distributed applications.

By learning RDMA (Remote Direct Memory Access) programming, you gain the following skills:

1. Efficient data transfer: Ability to perform high-speed, low-latency data transfers between computers' memory directly, without involving the CPU or operating system.
2. Network programming expertise: Proficiency in programming for RDMA-enabled networks, understanding network protocols, and socket programming.
3. Memory management: Understanding of memory allocation, deallocation, and efficient memory access techniques required for RDMA programming.
4. Performance optimization: Skills in optimizing network and memory performance to maximize the efficiency of RDMA-based applications.
