comment RSH connection problem while running MPI program
Thanks for the reply.. yes I can ping lagrid03 and get a reply. I re-installed MPICH configured to run with ssh . also ran lagrid02: env RSHCOMMAND=ssh mpirun -np 4 a.out and I got lagrid02 connection refused p0_14201: p4_error: Child process exited while making connection to remote process on lagrid02: 0 FYI, lagrid02 is the Master node

comment Monitoring Power on Dell Cluster using SNMP
I can do an snmpwalk on the dell cluster which returns some snmpwalk -Oa -c public -v 1 192.168.2.66 system 1.3.6.1.4.1.674.10892.1.300.10.1.39 SNMPv2-MIB::sysDescr.0 = STRING: This system component provides a complete set of remote management functions for modular servers SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.674.10892.2 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (136194903) 15 days, 18:19:09.03 SNMPv2-MIB::sysContact.0 = STRING: root@localhost SNMPv2-MIB::sysName.0 = STRING: Dell Rack System - FNJTJN1 Do I still have to install Dell Linux OSMA ?

comment Monitoring Power on Dell Cluster using SNMP
Could you kindly elaborate on how I can actually use snmpwalk, Sorry for being so naive, but this is my first time I'm using SNMP and have zero knowledge . How to find power values from snmpwalk . I'd appreciate if you could guide me through this ?

comment Does cpu consume power differently while executing instructions and while being idle?
thanks tomtom.. that was an interesting piece of info .. I have one more question . Can CPUs be in C1 state while running at 2 Ghz ? Is'nt the frequency scaled down when the CPU is in C1 state ? (once HLT is executed) ?

comment Does cpu consume power differently while executing instructions and while being idle?
@user48838 : That does not answer my question - why should it consume more power while running an instruction and less power while not running any instruction ? (assume CPU is at constant frequency always)

comment How does a power graph of a server running a job look like when there is no CPU power management mechanism deployed
@user48838: so, if there is no power management enabled for CPU, the meter readings will not be affected by variation in CPU utlization . correct ?

Do current HPC clusters running Linux Kernel on x86 Platform have Ondemand GOvernors running in the kernel , which can change the P-states based on the CPU utilization ?

THis is not homework. I'm trying to find a research problem in the area of HPC power management. So i want to know the current technologies in this field

I have set it to Ondemand . I want the minimum frequency to be 1.6 Ghz instead of 800 Mhz , which I'm not able to

comment changing C-state governor
I have heard of ladder governors and menu governors that govern C states. So i was curious to know how to change the current governor from ladder governor to menu governor

comment changing C-state governor
What I wanted to know was actually this : If my current C-state governor is ladder governor, How do you change settings so that my C-state governor shall be menu governor (say)
