Binding process to multiple processors on Sun Solaris OS

I have a server running Solaris OS. I want to bind number of processors to a certain process. I have tried following commands:

1) ps: to get process id.

bash-3.00$ ps -ef | grep java
bileng 10708 10695   3 12:20:59 pts/1       0:26 /opt/billengine/jdk1.6.0_29/bin/sparcv9/java -Dprogram.name=run.sh -Xloggc:./jb

2) psrinfo: to get the processor id.

bash-3.00$ /usr/sbin/psrinfo
0       on-line   since 11/04/2013 16:22:17
1       on-line   since 11/04/2013 16:22:18
2       on-line   since 11/04/2013 16:22:18
3       on-line   since 11/04/2013 16:22:18
4       on-line   since 11/04/2013 16:22:18
5       on-line   since 11/04/2013 16:22:18
6       on-line   since 11/04/2013 16:22:18
7       on-line   since 11/04/2013 16:22:18

3) pbind: to bind process to the processor.

I want to bind processor number 4 to 7 to a process id say 10708. Hence, I tried following command:

bash-3.00$ /usr/sbin/pbind -b 4-7 10708       
/usr/sbin/pbind: invalid processor ID 4-7

4) However, when I try binding single processor id to a process id, then it works:

bash-3.00$ /usr/sbin/pbind -b 4 10708
process id 10708: was not bound, now 4

5) But my requirement is to bind multiple processors to a single process id.

I tried exploring all the man pages and documents, but unable get the clue.

Can anyone please suggest some pointers on the same.

Thanks.

Solution

  • The tool for doing this in Solaris is psrset

    You create a processor set with

     psrset -c 4-7

    This will return the ID of the new processor set

     created processor set ps_id

    Then you can bind a process to a processor set with

     psrset -b ps_id pid
