# Build the inline-dataset shortcut variant of a CUDA pack: the measurement of proto-metal/MEMHARD.md section 2.2
|
|
# (ledger M16) on NVIDIA. usage: make-inline.sh <pack-dir> <out-dir>
|
|
# Two text edits on kernel.cu, nothing else:
|
|
# 1. every dataset load `ds[expr]` in igneum_hash becomes `mh_word(ds, expr)`: the word is recomputed from the
|
|
# cache through memhard.h's mh_item (8 dependent cache reads and 9 mixer applications per word) instead of read
|
|
# 2. igneum_build copies the 256 MiB cache into the head of the dataset buffer instead of building items, so the
|
|
# `ds` pointer the hash kernel receives points at the cache (mh_word indexes words below 2^IGNEUM_CACHE_LOG2_WORDS)
|
|
# The dataset self-test of host.cu then FAILS by construction (it reads ds words expecting items) and the vectors
|
|
# PASS (mh_word gives the true words). The rate line is the number; run.sh checks the vector lines and ignores OVERALL.
