Running CAM for multiple days

[shagos@rsmas_miami_edu]

Hi all,
I am a new CAM3 user. I just run the the one day test and it worked fine.
But when I tried to run multiple days by changing 'nelapse'. Almost all my
output variables were zero arrays. Was there some thing else I should
have changed?
Thank you,

By default CAM outputs monthly mean files in output (h0) files so you need to run for at least a month to get output or specify higher frequency output in the namelist. See the CAM users guide for details:

Thank you,
I added the following lines to the namelist file
nelapse = -10
nhtfrq = -6
hoping It would run for 10 days and write out every six hours.
When I opened the nc history file using matlab however I found
Empty array: 0-by-26-by-64-by-128 for all the four dimentional variable such as "U".
The error file contains the following messages (many of them).
print_memusage iam 1 post-inidat. -1 in the next line means unavailable
print_memusage: size, rss, share, text, datastack= -1 76852 -1 -1 -1
and the output file says,
proc= 3 clump no = 23 clump id= 356 beg landunit= 1017 end landunit= 1021 total landunits per clump = 5

Thank you very much,

Did it produce a h0 file only (no h1,h2 files?). If so you have to add information about which variables you want to output on each file stream and how frequently (there are 6 streams available h0 through h5). The following three namelist inputs would output U,V every 6 hours on the 2nd stream (producing h1 files) with 10 samples per file (mfilt(2))

fincl2 = 'U','V'
nhtfrq(2) = -6
mfilt(2) = 10

Good luck!

Thank you,
That seems to have worked.

Hi I am running CAM with the following configuration and it is writing the history files but not the restart files and the pointer file for restart? Does any one has any idea as to what could be happening?
caseid = 'cam_run04'
nelapse = -60
nhtfrq = 72
mfilt = 10
fincl1 = 'PRECT'
hfilename_spec(2) = 'cam_run04_h%t.%y-%m-%d.nc'
avgflag_pertape(2) = 'X'
start_ymd = 19980101
mss_irt = 300
nsrest = 0

Thank you,

Hello Everyone,
I have been running CAM on bluefire using 32 processesors. It runs for about 20 days and the six hour limit is up. My question is what is the normal speed of cam in such a setting, i.e is it that slow or I am doing something wrong. Also, is there a script that I can use to submit the restart runs automatically?
Thank you very much,

Hi all,
How do you turn Hack convection on/off on CAM3.0.
Thank you,
