nmrd?

I'm seeing warnings like this

"*WARNING* nmr: nmrd did not respond on lab04"

in my log files while doing a drc with assura (version below). I've not been able to track down what component "nmrd" actually is to troubleshoot. Can someone perhaps point me in the right direction? My runs commence (and successfully finish) after about 60 of these warnings.

Assura (tm) Physical Verification Version av4.1:Production:dfII6.1.5-64b:IC6.1.5-64b.500.5
Release 4.1_USR2_HF10

"nmrd" is not a component but a Cadence daemon (see http://support.cadence.com/wps/mypoc/cos?uri=deeplinkmin:ViewSolution;solutionNumber=20227707 for details). You can probably ignore this warning.

Thanks. Unfortunately I do not have access to the cadence kb. Barring any way to post more details on that solution on the forum, is there any place in the documentation you might be able to point me to? I haven't found any references to this daemon in my searching.

I will not post the entire nmrd FAQ here, but the key aspects are that it is really only needed for remote runs. However, for historical reasons, it also tries to be used whenever multiCPU is used.

You should be able to suppress the problem by doing:

setenv ASSURA_NO_NMRD 1 # if using csh
export ASSURA_NO_NMRD=1 # if using bash/ksh

before launching Virtuoso/Assura.

Of course, if you are really running remote Assura jobs, then it is needed but presumably that's not the case. nmrd is used to deal with mapping file names when on remote systems.

Regards,

Andrew.

Thanks Andrew. I will set this env variable as I am not running remote jobs. Is any of this (remote jobs) covered in the docs? I'm really surprised I did not encounter it in my searching but I would be interested to learn more.

It's in chapter 1 of the Assura Physical Verification User Guide in a section entitled "Running the Assura Tool Using Remote Job Submission".
