HPC Cluster Blog - GTX vs Tesla
Wednesday, 23 April 2014 13:19

A comparison of high-end GTX and Tesla GPUs for double-performance computing

Many of our customers have discovered that high-end NVIDIA GTX cards, such as the GTX Titan, offer a relatively low-cost alternative to NVIDIA Tesla cards such as the K20 or K40. Like the Teslas, the Titans offer double-precision calculations with comparable TFLOPS and number of CUDA cores. Unlike the Tesla cards, a Titan costs around $1,000, while a Tesla card can cost three or four times more.

HPC Cluster Blog - SSD vs HDD

SSD vs. HDD - or when to choose ove over the other

At Advanced Clustering, we hear a lot of opinions for the use of both solid state drives (SSDs) and standard hard disk drives (HDDs), and each has its own pros and cons depending on what their use will be. While there are advantages and disadvantages to each one, the top considerations when deciding between the two are capacity, cost, reliability, and speed.

Spinning disks are currently available in 500GB, 1TB, 2TB, 3TB, and 4TB sizes on the SATA side, with , while SSDs much less storage space, starting at 60GB and going up to 512GB.  For purposes of this discussion, we're sticking with SATA SSDs, as opposed to PCIe-based SSDs.  Now, there are larger SATA SSDs, but they are considerably more expensive and in shorther supply due to lower demand, thus we did not include them either in our testing.

HPC Cluster Blog - Memory Amount Limits
Friday, 21 March 2014 15:14

Memory amount limits: What's possible for your system?

The appropriate amount of memory for a particular node or server is usually best determined by looking at the number of memory channels available on the system's motherboard. These channels are communication pathways that run between the memory and the memory controller, a component inside the processor chips; more channels generally translate to a faster data transfer rate. In order to take advantage of the fastest data rate possible, all channels should be filled with at least one memory stick.
