-This directory contains a program for benchmarking various
-synchronization and concurrent programming mechanisms in ACE.
-
-To build the program, do a make on the top level Makefile (or,
-on NT, open Synch_Tests.dsw and build evey project in it.)
-There are several modules which perform different benchmarking
-measurements in subdirectories. Here is a short description of all
-the subdirectories:
-
- Synch_lib: This directory contains interface definitions required
- by both main program (synch_driver) and other modules.
- Base_Test: This directory contains a set of baseline tests. They
- measure the time to obtain a lock without contension,
- or trying to objtain a lock with contension.
- Perf_Test: This directory contains a set of performance tests.
- They measure the opeation performed by spawning a
- bunch of threads and let these threads compete with
- each other in obtaining a lock.
-
-There'll always be a "Method" object in each module subdirectory.
-They defines the method used in benchmarking and usually takes some
-options which can be defined in the 'svc.conf' file. Beside from this
-"Method" object, there are also a lot of "Test" objects that define
-the mechanism to be tested.
-
-Executing the program: the synch_driver performs various benchmarking
-according to the "script" defined in 'svc.conf' file. All command
-line options applicable to ACE's Service_Config class can be used.
-
-The entries in svc.conf file are always in groups. Each group
-consists of several svc.conf entries. The first entry in each group
-is the "Method" entry which defines the methodology used in the test.
-The rest of the entries are "Test" entries which define the mechanism
-to be test using the "Method".
-
-At this moment, you can not have entries with the same object (either
-"Method" object or "Test" object) in one svc.conf file. Therefore, at
-this moment, there can only be two groups in the svc.conf. Of them,
-each "Test" can only be performed once. Therefore, there's no way to
-benchmark using the same method with differnt configurations within
-the same svc.conf file. However, this can be easily overcome by
-defining multiple svc.conf files and invoking the synch_driver with
-different svc.conf file.
-
-There'll be more detailed description about how a "Method" object can
-be configured in respective subdirectory. \ No newline at end of file
