R-specific environment variables: Naming convention?
In base R, there are lots of environment variables with either prefix
'R_' or '_R_', e.g. R_ENABLE_JIT and _R_RNG_VERSION_. I always
considered R_* variables to be "public" and _R_*_ ones being
"internal" but realized I don't have a reference for this. Is this
true, or is there another reason? Is the difference between the two
kinds documented anywhere?
Thank you,
Henrik

It looks to have compiled its own Rterm.exe, and segfaults when running it?...

Revert to R 3.2.x code of logicalSubscript in subscript.c?
...vectors of length 1e8 like you did (which will not fit in cache) and
vectors of length 1e5 (which will fit in at least the L3 cache). I
ran tests on an Intel Skylake processor (E3-1270v5 @ 3.6GHz), using
gcc 7.2 with -O3 -march=native -mtune=native.
I got the following results with R-3.4.2 (with R_ENABLE_JIT=0, which
is slightly faster than using the JIT compiler):
R-3.4.2, LARGE VECTORS:
