набор инструментов для отладки и профилирования программ (a suite of tools for debugging and profiling programs)
CACHEGRIND OPTIONS
--I1=<size>,<associativity>,<line size>
Specify the size, associativity and line size of the level 1
instruction cache.
--D1=<size>,<associativity>,<line size>
Specify the size, associativity and line size of the level 1
data cache.
--LL=<size>,<associativity>,<line size>
Specify the size, associativity and line size of the
last-level cache.
--cache-sim=no|yes [yes]
Enables or disables collection of cache access and miss
counts.
--branch-sim=no|yes [no]
Enables or disables collection of branch instruction and
misprediction counts. By default this is disabled as it slows
Cachegrind down by approximately 25%. Note that you cannot
specify --cache-sim=no and --branch-sim=no together, as that
would leave Cachegrind with no information to collect.
--cachegrind-out-file=<file>
Write the profile data to file rather than to the default
output file, cachegrind.out.<pid>. The %p and %q format
specifiers can be used to embed the process ID and/or the
contents of an environment variable in the name, as is the
case for the core option --log-file.
