[Swift-devel] Issues with Montage & Swift-CDM

Thu Mar 22 16:53:37 CDT 2012

Thank you Jon. I am using swift-0.93 (this is in our Cluster). So I do not need to check for garbage-collector errors.

I forgot to mention one point about concurrent mappers. The pipeline swift benchmark I wrote uses concurrent mapper too. Last week I ran the benchmark successfully regardless of the concurrent mappers location (I tried various location for concurrent mappers). So I guess the location of the concurrent mappers wont be an issue.

Thank you
Emalayan

I'll run with those rules.  I saw the garbage collection exception in the log file.  The exception may be causing no harm, but it probably shouldn't be throwing an exception at all so this may help fix it in trunk.

But it just occurred to me, which swift are you using again?  I am running with the copy I grabbed from Justin's directory.  Are you running that as well or with 0.93?  If with 0.93 you will not see that exception because that version does not have the swift garbage collector so we should not waste time with that exception.

>Emalayan, it does not look like those scripts expect files to be in a certain location, at least that is not what is intended.  In the main swiftscript, when you call the other functions you pass the directory name you want the intermediate files to be stored in.  Then in the SwiftMontage_Batch functions it uses those directories you passed to map input/output files.  The only things that are expected to be in certain places are the raw_dir and header.hdr.  Those have to be in the pwd.  However I will continue debugging to make sure those assumptions I made are holding.
