Thanks Bert,

Let's neglect the network for the moment and assume we're running the application on a single machine with local storage - disk - across the many cores available. Would the type of storage play a significant role on the application performance. As an example, if we are using the RAM (by creating filesystems from the RAM storage available) vs using regular HDD; is this going to make any difference?

That's a difficult question to answer. Many of our default algorithms use disk and can become I/O intensive. However, those same algorithms can be directed to do "direct" calculations, avoiding disk and becoming compute intensive. A third variable is when you run in parallel, where the network bandwidth and latency can become an issue for certain algorithms.

Thanks,

Bert

Hi all,

This is my first post on this community. I have a "technical" question about the NWChem software. Is it considered as an I/O intensive application or it is more of compute (i.e. CPU) intensive?

Thanks...
