Kinda disappointed about the lack of historical data given about the sort of supercomputers used for weather modelling over the years. Mainly because I want to know which era of weather forecasting could conceivably run on my PC, my phone, or the latest Raspberry Pi.
- ghaff 10y agoAs I recall from when I followed the supercomputer space in more detail, weather was one of the areas that tended to use specialized supercomputers like IBM BlueGene rather than big clusters because the weather models were harder to parallelize. Go back in time and I'm sure you'll see quite a few high-end IBM pSeries. Go further back and there will be things like Cray vector machines.
- angry_octet 10y agoNo it is inherently a well parallelizible problem, it is just that code was originally written for the original vector supercomputer CPUs (Cray, NEC SX) and had to be rewritten for MPI style clusters. It ironic because now we have to rewrite everything to use SIMD/vector accelerators (GPUs).
