Parallel Programming and Computing Platform

Parallel Programming and Computing Platform
What is CUDA? Enroll today! Intro to Parallel Programming An open, online course from Udacity Instructors: Dr. CUDA® is a parallel computing platform and programming model invented by NVIDIA. With millions of CUDA-enabled GPUs sold to date, software developers, scientists and researchers are finding broad-ranging uses for GPU computing with CUDA. Identify hidden plaque in arteries: Heart attacks are the leading cause of death worldwide. Analyze air traffic flow: The National Airspace System manages the nationwide coordination of air traffic flow. Visualize molecules: A molecular simulation called NAMD (nanoscale molecular dynamics) gets a large performance boost with GPUs. Background GPU Computing: The Revolution You're faced with imperatives: Improve performance. Not anymore. Using high-level languages, GPU-accelerated applications run the sequential part of their workload on the CPU – which is optimized for single-threaded performance – while accelerating parallel processing on the GPU.

BITMAIN AntMiner U1 (MOQ: 500 units) U1 has been sold out. AntMiner U1 is an USB miner with 1 BM1380 chip. Rated 1.6 GH/s, 2 watt power from the USB port. CUDA CUDA is a parallel computing platform and application programming interface (API) model created by Nvidia.[1] It allows software developers and software engineers to use a CUDA-enabled graphics processing unit (GPU) for general purpose processing — an approach termed GPGPU (General-Purpose computing on Graphics Processing Units). The CUDA platform is a software layer that gives direct access to the GPU's virtual instruction set and parallel computational elements, for the execution of compute kernels.[2] Background[edit] The graphics processing unit (GPU), as a specialized computer processor, addresses the demands of real-time high-resolution 3D graphics compute-intensive tasks. Programming abilities[edit] Example of CUDA processing flow Copy data from main memory to GPU memoryCPU initiates the GPU compute kernelGPU's CUDA cores execute the kernel in parallelCopy the resulting data from GPU memory to main memory CUDA 8.0 comes with these other software components: Advantages[edit]

Course on CUDA Programming Course on CUDA Programming on NVIDIA GPUs, July 22--26, 2013 The course will be given again in Oxford in July 2014, almost certainly the week of July 21-25. We hope to confirm this and have the online registration / payment system set up by early May. This is a 5-day hands-on course for students, postdocs, academics and others who want to learn how to develop applications to run on NVIDIA GPUs using the CUDA programming environment. The course consists of approximately 3 hours of lectures and 4 hours of practicals each day. Costs for the course will be as follows: £100 for those from Oxford University and other members of the e-Infrastructure South consortium (Bristol, Southampton, STFC and UCL) £200 for those from other UK universities £500 for those from other government labs, not-for-profit organisations, and foreign universities £2000 for those from industry (this will include lunch each day) To encourage early registration, the costs will increase by 50% after July 4th.

25 GPUs brute force 348 billion hashes per second to crack your passwords It’s our understanding that the video game industry has long been a driving force in new and better graphics processing hardware. But they’re not the only benefactors to these advances. As we’ve heard before, a graphics processing unit is uniquely qualified to process encryption hashes quickly (we’ve seen this with bitcoin mining). This project strings together 25 GPU cards in 5 servers to form a super fast brute force attack. It’s so fast that the actual specs are beyond our comprehension. The testing was used on a collection of password hashes using LM and NTLM protocols. [via Boing Boing]

Methodologies for Network-level Optimization of Cluster Computers supervisors: Dr Peter Strazdins A Beowulf-style cluster computer is a parallel computer using Commercial-off-the-Shelf switch-based network to communicate between the processors. The ANU Beowulf cluster Bunyip is such a cluster based on Fast (100Mb) Ethernet switches. Clusters have proved a highly cost-effective high performance computer model, and have largely displaced the traditional massively parallel computers built with expensive vendor-supplied networks. The switch-based networks used by clusters not only support normal point-to-point messaging (via TCP/IP in the case of Ethernet networks), but data transfers by collective communications (e.g. multicasts) and remote direct memory access (RDMA). In partnership with the local company Alexander Technology, this project will investigate evaluating the effectiveness of various hardware and software configuration options for various networks. Hardware configuration options include using multiple NICS (channels).

OpenVIDIA - OpenVIDIA Hack and / - Password Cracking with GPUs, Part I: the Setup Bitcoin mining is so last year. Put your expensive GPU to use cracking passwords. When the Bitcoin mining craze hit its peak, I felt the tug to join this new community and make some easy money. Then Bitcoin tanked. Legitimate Reasons to Crack Passwords Before I get started, let's admit that there are some pretty shady reasons to crack passwords. That said, like with lock picking, there are legitimate reasons to crack passwords, particularly for a sysadmin or Webmaster: Test local users' password strength. In fact, many Linux systems will run a basic dictionary attack when you change your password to evaluate how weak it is. An Introduction to Password Hashes Password hashes were created to solve a particularly tricky problem. When you log in to a Linux system, the password you enter gets converted into a hash with the same algorithm originally used when you first set your password. How Password Cracking Works On a very basic level, password cracking works much like a regular login.
