SC09 [T-1 day]: The booth is (mostly) up

A JackRabbit JR4, and a Pegasus deskside supercomputer are there (booth 635 on the show floor, Intel Partner Pavilion). We ran into a cooling issue though, so I had to pull one of the GPU cards. Working on a few other things to fix. Might have a corrupted zip file for the demo (ugh). Will […]

SC09 [T -3 days] shipped everything to the booth by UPS

Hopefully it will get there. Had to disassemble the CPU coolers in the Pegasus, and remove the disks from the JackRabbit. Pegasus has a pair of rocking Nehalem W5590 chips, 32 hard disks, 48 GB ram, a Tesla, a GTX260, and a pair of 10GbE ports. The JackRabbit was doing 1.8GB/s reads and 1.3 GB/s […]

SC09 booth bits

Ok, here’s the scoop. We will be in the Intel Partner Pavilion booth #3077. We are going to be bringing a nice JackRabbit JR4 and a Pegasus-GPU unit. The JR4 will have a pair of nice fast Intel Nehalem CPUs in it (probably X5550’s), and the Pegasus will have a pair of W5580’s. Both units […]

The joy that is mmap …

Mmap is a way to provide file IO in a nice simple manner. Create a buffer area, and as you read/write into that buffer, this is reflected physically into the file. Oversimplification, but this is basically what it is. In most operating system, mmap makes direct use of the paging paths in the kernel. Why […]
