Is he sure about 512GB of RAM? That's a lot of memory. Even the 32-core memory-optimized AWS instances only have 244GB.
- nippoo 12y agoWhere I'm currently working (computational neuroscience / data analysis) we've just had to upgrade our servers and 512GB is only just enough for some datasets. A couple of the labs nearby (genomics) share a cluster of ~10 machines with 1.5TB RAM each. So no, 512GB isn't stupidly high (though it's still uncommon!). (Large SQL servers, etc, often have this much RAM)
- sjtrny 12y agoI once used over 500GB on a university research server simply using MATLABs backslash (linesr system solver) operator when processing a single image. I accidentally forgot to scale the image down from original resolution of 5MP. I woke up to an email from a very alarmed sys admin. Anyway it's super easy to use that amount of RAM.
- tromp 12y agoAdmittedly, the 512GB in one server is mostly for convenience. In each round, I run 8 processes each using 63GB, which could in principle also be farmed out to other machines with some more administrative and monitoring overhead.
