Similar problem of unknown resource walltime

Hi,

I met with a similar problem when running the I-TASSER using parallel runstyle. I tried all the methods said in the privous post, but still get this:

2.4.2 running pair ................
FORTRAN STOP
3.1 do threading
start parallel threading PPA
Unable to run job: unknown resource "walltime".
Exiting.
start parallel threading dPPA
Unable to run job: unknown resource "walltime".
Exiting.
start parallel threading dPPA2
Unable to run job: unknown resource "walltime".
Exiting.
start parallel threading sPPA
Unable to run job: unknown resource "walltime".
Exiting.
start parallel threading MUSTER
Unable to run job: unknown resource "walltime".

start parallel threading wPPA

Exiting.
start parallel threading wdPPA
Unable to run job: unknown resource "walltime".
Exiting.
start parallel threading wMUSTER
Unable to run job: unknown resource "walltime".
Exiting.

My script is: /share/backup/yzheng/I-TASSER/I-TASSER2.1/I-TASSERmod/runI-TASSER.pl -libdir /share/backup/yzheng/I-TASSER/I-TASSER2.1 -seqname A737V -datadir /home/yzheng/I-TASSER/A737V -usrname yzheng -runstyle parallel

And I've replaced the runI-TASSER.pl with the latest verison (if it is the one in the I-TASSER2.1.tar.gz package online). Could you tell me how to do trouble-shooting? Besides, is there any condition limitation for running in parallel style? Thanks!

ps: I guess I met with two problems, one is 'Fortran stop' when running pairs, which also appears in serial runstyle, the other one is 'unknown resource walltime',which doesn't show up in serial runstyle. But serial runstyle is too slow to run.
