+*** To run libMicro testsuite with stepper disabled ***
+
+To get a more consistent result of libMicro benchmark run, we need to disable the
+stepper to prevent it from causing wide variations in results. See rdar://6243819
+for details.
+
+So to run libMicro test suite with stepper disabled, use 'coreos_bench' script
+instead of 'bench' script.
+
+For example:
+./coreos_bench > output.txt
+runs the libMicro test suite excluding the lmbench tests and gives you a text file named output.txt with the results of one run, with stepper disabled.
+
+Note:
+1) We need '/usr/local/bin/pstates' to disable the stepper. Install AppleInternal package
+which provides '/usr/local/bin/pstates'.
+
+2) 'coreos_bench' script is used exactly like the 'bench' script. All the usage examples for
+'bench' script in this readme file also holds true for 'coreos_bench' script.

*** Makefile ***
The Makefile invokes Makefile.Darwin which invokes Makefile.com.Darwin.
bin-ARCH where ARCH is the default or specified when building via
the ARCH flag.
+Note:
+1) The binaries of apple added tests are placed in a directory called
+ apple/bin-ARCH
+
+2) All the binaries under bin-ARCH and apple/bin-ARCH are code signed
+ during build.
+
options for invoking Makefile are:
ARCH defaults to i386
- if you just want to build for ppc, you can specify
- make ARCH=ppc
- this will put the results in bin-ppc
to build fat/multi architecture, specify
make ARCH=fat
- the makefile will automatically build with ARCH_FLAG="-arch ppc -arch i386 -arch x86_64" and put the results in bin-fat
+ the makefile will automatically build with ARCH_FLAG="-arch i386 -arch x86_64" and put the results in bin-fat
+
+ to build for ARM architecture,
+ first set an environment variable 'SDKROOT' to point to iPhone sdk
+ make ARCH=ARM_ARCH where ARM_ARCH can be armv6 or armv7
+ this will put the results in bin-ARM_ARCH
to build with only two of the architectures see below
ARCH_FLAG defaults to -arch $(ARCH)
to build fat/multi architecture, specify
- make ARCH_FLAG="-arch ppc -arch i386" ARCH=fat
+ make ARCH_FLAG="-arch i386" ARCH=fat
this will put the results in bin-fat
OPT_FLAG defaults to -g
- to build optimized, specify make OPT_FLAG=-s
+ to build optimized, specify make OPT_FLAG=-Os
SEMOP_FLAG defaults to -DUSE_SEMOP
to eliminate SEMOP usage, specify make SEMOP_FLAG=
this is needed on some lower-end systems (e.g. M63)
These can be combined, e.g.
- make ARCH=ppc SEMOP_FLAG=
+ make ARCH=i386 SEMOP_FLAG=
*** Before running benchmarks ***
bench lmbench_bw_unix
+By default the script will run only the libMicro testsuite excluding the lmbench tests.
+To run the libmicro testsuite with the lmbench tests included, just pass the -l parameter. e.g,
+
+ bench -l
+To run only the lmbench testsuite
+
+ bench lmbench
+
+To display the usage, just do
+ bench -h
+

trivial case. The tests starting with "lmbench_" were ported from
the lmbench suite, so they might be good examples as well.
+*** A note regarding future changes in bench.sh script ***
+coreos_bench.sh script is almost identical to bench.sh script, except that it
+has additional code to disable the stepper during libmicro benchmark run.
+
+In future, if bench.sh script is modified, make sure the changes reflect
+in coreos_bench.sh script also.
+
*** Things to do ***
* port the rest of the lmbench benchmarks into this framework
Due to rdar://4654956 and its original, rdar://2588252 you cannot
run these tests on Leopard without removing the cascade_lockf test.
There may be other tests which panic a Leopard system.
+
+*** benchDS notes ***
+
+From rdar://problem/7468995 add the ability to benchmark the key APIs
+for server daemons. In particular, a test binary is added for each of:
+
+ ODQueryCreateWithNode() (standard User, Groups, and Hosts records)
+ getaddrinfo() (hosts and ports)
+ mbr_check_service_membership()
+ mbr_check_membership()
+ getpwnam()
+ getpwuid()
+ getgrgid()
+ getpwent()
+ getgrent()
+ getgrnam()
+
+The script benchDS is provided to run a standard set of tests presuming
+that the tests are run by root on a system configured with an OD binding.
+The OD server (local or remote) must have a set of accounts created with
+od_acount_create shell script. This script must also be run as root,
+and passed a single argument of the number of users to create. It creates
+od_test_{1..N}, and all belong to a ds_test_group1(gid 1211). In addition,
+ds_test_group2(gid 1212) is created which has no users as members. User ids are
+set sequentially from 5000. In order to administer the OD server, it assumes
+user 'diradmin' and password 'admin' are the OD admin.
+
+Also, these tests consult the APIs listed, which can be run against the local
+account info, or even Active Directory.
+
+Thus, the quick recipe is:
+ Install X Server
+ Enable OD, and create directory admin user 'diradmin' with password 'admin'
+ As root run: od_account_create 1000
+ Now run the test, as root: ./benchDS 1000 > output-file
+
+
+In addition, od_account_delete 1000 will delete the 1000 users created with od_account_create.
