NAME
bustest - measure performance of the I/O bus
SYNOPSIS
% bustest -config config_file -firmware firmware [-unit unit] [-cpuread] [-cpuwrite] [-dmaread] [-dmawrite] [-dmaboth]
DESCRIPTION
Bustest measures the data transfer rate(byte/sec) of the I/O bus using the DMA engine of the Myrinet interface.
The output format of bustest is as follows. 
cpu  read: WWW          I/O -> CPU
cpu write: XXX          CPU -> I/O
DMA  read: YYY          I/O -> Memory
DMA write: ZZZ          Memory -> I/O
OPTIONS
-config config_file
Config_file is used for network configuration.
Default is "pm.cnf".
-firmware firmware
Firmware file is used for NIC firmware.
Default is "pm.mcp".
-unit unit
Unit is used as the unit number of the Myrinet card to be tested.
Default is zero.
-cpuread
-cpuwrite
-dmaread
-dmawrite
Only specified tests are executed.
-dmaboth
Two DMA engines in LANai 7 are used simultaneously.
Default is all tests.
ERRORS
Bustest outputs the following error messages when any error occurs:
myriMapLANai: error
The Myrinet interface cannot be initialized.
