Fortran Matrix Multiplication Loop, Tagged to Be Compiled for the Accelerator do i 1,n1 do k 1,n3 c(i,k) 0.0 do j 1,n2 c(i,k) c(i,k) + a(i,j) + b(j,k) enddo enddo enddo turn into library calls, allocating memory, moving data and invoking kernels. These five steps are the same that a programmer has to perform when moving a program from a host to CUDA or Brook or other GPU-specific language. At least four of them can be mostly or fully automated, which would simplify programming...

It recently occurred to me that in the eight years or so I've been writing this column, I've never covered file servers. I've covered secure file transfer, for example, via scp, rsync and vsftpd, which certainly is important. But, I've not covered file serving, specifically, allowing users to mount persistent network volumes that let them use networked server disk space as though it were a local disk. This has all sorts of productivity-and operations-related benefits it's (usually) easy for end...

Hardware

Watch out Here comes the Networked Media Tank. daniel Bartholomew Linux-powered devices are everywhere. They're so ubiquitous that Linux often isn't even mentioned. It's just there. One case in point is the Popcorn Hour A-100. Linux isn't mentioned in the technical specifications of the device at all. What is mentioned are the formats and codecs and other capabilities of the device, and what a device it is. The Popcorn Hour is a reference hardware implementation for a new Linux-based middleware...

Debugging

Matloff and Salzman's The Art of Debugging with GDB, DDD, and Eclipse (No Starch) Despite the importance of debugging, many new programmers are unaware of techniques that reduce the time needed to find and fix programming errors. To the rescue is the new book The Art of Debugging with GDB, DDD, and Eclipse by Norman Matloff and Peter Jay Salzman, published by No Starch Press. Leveraging the open-source development tools GDB, DDD and Eclipse, the book illustrates an assortment of real-world...

When I first started using computers, High-Performance Computing basically meant how fast a person could type. People were considered high performance if they could type faster than the IBM electric typewriter could smack out the letters. In fact, if you haven't seen a race between a person on a manual typewriter versus a person on an IBM Selectric golfball typewriter, you haven't lived. Times quickly changed, however, and now instead of counting characters per second, we use terms like...

VIDIA's CUDA (Compute Unified Device Architecture) makes programming and using thousands of simultaneous threads straightforward. CUDA turns workstations, clusters and even laptops into massively parallel-computing devices. With CUDA, Linux programmers can address real-time programming and computational tasks previously possible only with dedicated devices or supercomputers. Do you want to use hundreds of processing cores with Linux today If so, take a look at running CUDA on the NVIDIA...
