Finding information about the CPU programatically

Sonison James — Sun, 22 Jun 2003 13:43:45 GMT

Hello,

I would like to know the following for each CPU, programmatically

1. Type
2. Model
3. Speed

I am able to get the number of active CPUs and the speed of each CPU by using pstat_getdynamic() and pstat_getprocessor(). For CPU Type I am using sysconf(), however this does not give the model for each CPU. Also for getting the CPU Model I am using the model command, which again has the same problem.

Any information about APIs that lets me get all the information on a per CPU basis would be highly appreciated.

Thanks and Regards
Sonison James

Hi Sonison,

Although this doesn't answer your question can I just add the information must be the same for each processor, i.e. they must all be the same model, type and speed.

I think that the structures that hold the information are global (not per SPU) hence I don't believe writing code to find this will be of much use?

Regards,

James.

Hell,
You can use the att' scripts
OR:
################# CSTM #################
/usr/sbin/cstm << EOF >> /tmp/cstmmap1.tmp
map
exit
EOF
set CPU=`grep CPU /tmp/cstmmap1.tmp |awk '{print $1}'|sort -u`
foreach i ($CPU)
/usr/sbin/cstm << EOF >> /tmp/cpu1
map
sel device $i
il
SaveAs
cpu
EOF
set CACHE=`grep "Instruction Cache" /tmp/cpu |awk '{print $4}'|sort -u`
set PDC=`grep "PDC Firmware Revisi" /tmp/cpu |awk '{print $4}'|sort -u`
set CPUPATH=`grep CPU /tmp/cstmmap1.tmp |awk '{print $2}'|sort -u`
end
endif
endif
#############################
echo "Processors:`/usr/sbin/ioscan -C processor |grep processor |wc -l`" >>/tmp/cpu-info
set CPUSPEED=`echo "itick_per_usec/D" |adb -k /stand/vmunix /dev/kmem |tail -1|awk '{print $2}'`
echo "Processors Speed: "$CPUSPEED "Mhz">>/tmp/cpu-info
foreach I ($CPUPATH)
echo "The CACHE size on Processors in path" $I "is "$CACHE "[Kbyte]" >>/tmp/cpu-info
end
echo "The PDC Firmware Revisi is" "$PDC" >> /tmp/cpu-info

Hello,

Thanks for the information and the scripts. Even the scripts seems to be assuming that all the CPUs have the same model and speed, so I hope that I can safely make that assumption too in my code.

Thanks and regards
