TTCP Benchmark README file
This directory contains a modified version of the TTCP benchmark that
uses the TAO ORB. TTCP is used to measure the throughput of COOL
for sending different data types. This code tests sequences of short,
long, octet, char, double, and richly-typed data such as a struct.
Organization
------------
client.cpp Client main program
server.cpp Server main program
ttcp.cpp Client & Server side stub
ttcp.H Client & Server side stub header file
sk_ttcp.C Server skeleton implementation file
sk_ttcp.H Server skeleton implementation header file
ttcp_i.cpp Implementation of the interface
ttcp_i.h Header for the implementation
utils.cpp Utilities to calculate throughput
ttcp_decl.h Common declarations
Results
-------
Throughput results are displayed on stdout.
Running the test
-----------------
Server
------
Usage:
server [COOL options] [Common options]
[COOL options] ** these are required **
cool-tcp://<THIS_HOSTNAME>:<THIS_HOST_PORT> -cool-tcp -cool-iiop
THIS_HOSTNAME : the name of the host that the server will be running on. This is useful
if you want to specifya different interface (e.g. ATM, 100Mbit Ethernet)
THIS_HOST_PORT: is the port number at which the server will start the high
priority servant. The low priority servant will be created at
(THIS_HOST_PORT+1).
[Common options]:
-l ## length of bufs read from or written to network (default 8192)
-v verbose: print more statistics
-d ## set debug level
-f X format for rate: k,K = kilo{bit,byte}; m,M = mega; g,G = giga
-L ## Output file name to store results
Example:
server cool-tcp://tango.cs.wustl.edu:3000 -cool-tcp -cool-iiop -d 1
The Output might look like this:
stringified obj reference = IOR:000000000000001649444C3A747463705F73657175656E63653A312E3000000000000002000000000000004900010000000000103132382E3235322E3136352E313430000BB80000000000290000000001000000010000001C0073193B00000002EFFFED98000000000000000A80FCA58C00000BB8000000434F4F4C000000290000000001000000010000001C0073193B00000002EFFFED98000000000000000A80FCA58C00000BB8
Entering boa->run ().
Client
------
Usage:
client -cool-tcp -cool-iiop [Common options]
[Common options]:
-l ## length of bufs read from or written to network (default 8192)
-v verbose: print more statistics
-d ## debug level
-f X format for rate: k,K = kilo{bit,byte}; m,M = mega; g,G = giga
-h ## Remote host to send data to
-p ## Port number"
-S ## Total Data Size to be sent
-L ## Output file name to store results
-q <type> Send Sequence: Enumeration for various data types:
s = short, l = long, d = double, c = char
o = octet, S = BinStruct
Example:
# The following example will send 10Mb of data, using a megabyte rate,
in 1024 byte chunks, to host tango.cs.wustl.edu, to port 3000, and will send shorts
client -cool-tcp -cool-iiop -S 10240000 -f m -l 1024 -h tango.cs.wustl.edu -p 3000 -q s
The Output might look like this:
Composed IOR string as: cool-tcp://tango.cs.wustl.edu:3000
data size = 10240000, buflen = 1024, nbuf = 10000
ttcp-t: 10240000 bytes in 2.81 real seconds = 27.82 Mbit/sec +++
ttcp-t: 10000 Server Method calls, msec/call = 0.29, calls/sec = 3561.29
ttcp-r: 10236928 bytes in 2.81 real seconds = 3560.03 KB/sec +++

Compiling
---------
Setup the CHORUS COOL environment variables before compiling, the
following is an example. You would typically want this in the shells'
resource file (e.g. .cshrc.mine). The example provided is for a C
shell.
setenv CHORUS_ROOT /project/doc/miniCOOL/minicool.r4.3/solaris2.5-CC-mt
set path = ($path /project/doc/miniCOOL/minicool.r4.3/solaris2.5-CC-mt/bin)
setenv LD_LIBRARY_PATH /project/doc/miniCOOL/minicool.r4.3/solaris2.5-CC-mt/lib:$LD_LIBRARY_PATH
setenv MANPATH /project/doc/miniCOOL/minicool.r4.3/solaris2.5-CC-mt/man:$MANPATH
Makefiles are provided. Use make to compile.
You can either run the server in the background in the same window as
the client or open a separate window for the client and server.
