HPC Cluster Blog - SSD vs HDD
Monday, 31 March 2014 08:22

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 their 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

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.

HPC Cluster Blog - HPC in the Cloud

Is HPC in the cloud right for you?

Over the years, I’ve attended many birds of feather where the topic was whether or not there was a future in moving HPC into the cloud.  There were plenty of vigorous debates for and against, and they tended to go this way:

 

For:

The most obvious argument for moving your computing to the cloud is eliminating the need for purchasing and maintaining hardware.  Most of the users are scientists or engineers who don’t want to spend their time managing a cluster.  By moving to the cloud, they allow others to buy, power, cool, and maintain the hardware while they focus on what they’re experts in.  The actual cost of a cluster is substantial, and the costs to house it, power it, and cool it are not insignificant.  Then, of course, someone has to administer and maintain it.  But there are many professors and engineers where this responsibility falls to them.  So, now they have to hire someone to maintain it, or do it themselves.  And if that’s the case, it takes away from their ability to do science.  With the cloud, you simply upload your data to the online resource, pay for the cycles you need, and once the job is complete, download the results to your local machine and do your work.  If you do not require constant access to a cluster to run your jobs, then this could be a viable option.
