# This query basically asks: How much faultspace area is there?

|
# It queries the same "SUM(t.time2 - t.time1 + 1)" as ResultsData.pm,
|
|
# but doesn't join over "result_GenericExperimentMessage", so the
|
|
# faultspace area is not repeated.

# The "COUNT(*)" part counts the number of equivalence classes
|
|
# (or the number of pilots in other words).

# We run with --inject-single-bit, so FAIL* produces one result
|
|
# per bit (8 * p.data_width).
|
|
# This means "area" matches the ResultsData.pm query and
|
|
# can be used as a denominator (to calculate marker percentages
|
|
# that work better between different execution modes, as we don't
|
|
# want to compare a variable that is "live" for 100 ticks to one
|
|
# that is "live" for 5):
|
|
# - area == SUM(resultsdata.faults) over all resulttypes

# In the IP benchmark every equivalence class is one tick long and

# one byte wide, so we expect the following relations:
|
|
# - weight == pilots == instruction count
|

# - area == injections == 8 * pilots
