[ncdf4] error converting GEIA data to netCDF
summary: I can successfully ncvar_put(...) data to a file, but when I
try to ncvar_get(...) the same data, I get
> Error in if (nc$var[[li]]$hasAddOffset) addOffset = nc$var[[li]]$addOffset else addOffset = 0 :
> argument is of length zero
How to fix or debug?
details:
R code @
https://github.com/TomRoche/GEIA_to_NetCDF
successfully (if crudely) uses R packages={ncdf4, maps, fields} to
+ extract data from a GEIA-distributed datafile

[RFC][SVE] Supporting SIMD instruction sets with variable vector lengths
...ys 1.
Anyway, I don't mind any name, really. Whatever is more mnemonic.

Once stepvetor (or iota) becomes a proper IR instruction, I'd like to
see this restricted to inlined syntax. The sequence { step*vec +
offset } only makes sense in the scalable context and the intermediate
results should not be used elsewhe...
