A Brief about RDMA, RoCE v1 vs RoCE v2 vs iWARP

Hello folks, Today we'll see what RDMA is and how different kind of network solutions work over Ethernet. For those who are wondering what these words are, this is a post about Networking and an overview can be, how to increase your network speed without adding new servers or IB over your network, wherein IB stands for InfiniBand which is basically a networking communication standard majorly used in HPC  that features very high  throughput  and very low  latency , for what HPC is, refer to my previous blog. This is how a Mellanox IB cable looks like In order, not to use IB, increasing the speed for Ethernet-based solutions is a better and cost-effective solution in many cases which is implemented using RDMA, thus saving cost and technology shift overhead for every admin out there. So let's see what RDMA is, RDMA stands for Remote Direct Memory Access  is a  direct memory access  from the  memory  of one computer into that of another without involving either one'

What is H.P.C. and how it works?

Hello Fellas, It's been a long break for me and the page, first of all, sorry for all this but now the page is back and active as it was. Today we'll be taking a deep dive into what HPC is, how it works and why so many people are talking about it. Starting with a basic introduction of what HPC stands for and what is basically means. HPC stands for High-Performance Computing and what it means is aggregating a big amount of computing power in order to solve large problems in almost all fields, there are problems which requires huge computing power which is thus provided by HPC solutions. Now let's talk about where you might have heard of HPC and related stuff. You might have heard of supercomputers used by many such companies like Google for AI and many other purposes which indeed consists of thousands of processors to tackle problems of huge sizes which requires a whole lot of calculations and data processing to achieve one goal or the other. Many scientists are using t
