package Whetstone is
procedure Small_Whetstone (Kilo_Whets : Positive);
pragma Inline (Small_Whetstone);
-- Performs the computational workload of a Hartstone task. The
-- computation is a scaled-down version of the one performed by the
-- full Whetstone benchmark program. An exception is raised if the
-- computation fails to satisfy an internal consistency check.
-- This procedure does not return any "result" from its
-- computation; its sole function is to give a Hartstone task
-- something to do.
function Compute_KWIPS return Positive;
-- Computes the raw speed of the Small_Whetstone benchmark, in the
-- absence of tasking, by determining how many thousands of
-- Whetstone instructions (Kilo-Whetstones) per second it can
-- execute. Raw speed is expressed in Kilo-Whetstone Instructions
-- Per Second (KWIPS). The performance of the Hartstone task set
-- will be measured against this non-tasking computation.
--
-- Note: the result is cached, any successive call will directly
-- return the result computed at the first call.
end Whetstone;
