    irun 11.10-s062 -R option and *W,WKWTLK "Waiting for a Exclusive lock" Reply

    My company recently upgraded from IUS 10.2 to 11.10. Our sim-regression suite uses the strategy of compiling a snapshot once (irun), then using that snapshot to run many different sim testcases in parallel (irun -R).

     With IUS 10.2, we had no trouble with kicking off multiple simjobs simultaneously,from the same INCA_libs dir.

    Now, with IUS 11.1,  we're getting some kind of file-locking warning whenever more than 1 job is started from the snapshot.  Basically, if I kick off 30 simjobs in parallel, they run serially (one most complete before the next one starts.)  So we are unable to simulate in parallel unless we compile each testcsae in its own separate directory.

     irun: *W,CSSF: HDL source files with -R option will be ignored.
    irun: *W,WKWTLK: Waiting for a Exclusive lock on file '/.../mysim/INCA_libs/irun.lnx86.11.10.nc/.ncrun.lock'. pid:2266.

     I'm confused.  I thought using the '-R' option tells irun *NOT* to reocmpile anything.  So why does IUS 11.1 still trying to lock files?
