Appion

Hi,

At some point duing the Appion hackaton I believe the default number of processors for the makestack jobs went from 1 processor to 2 processors. This will not help the job go any faster and it basically renders the extra processor unusable for the duration of stack creation. With the new students exploring appion right now, we anticipate there will be a lot of makestack jobs running and the number of idle processors will become significant. As garibaldi queues are at 48+ hrs, we're constrained to doing a lot of processing on guppy, so each processor we have is important.

Could we please change the default number of processors back to 1? A similar change was made earlier this year found in this issue:

For makestack, I imagine the change would ultimately be changing from this:
#PBS -l nodes=1:ppn=2

to this:
#PBS -l nodes=1:ppn=1

The number of requested nodes is also an issue on garibaldi, but for guppy it is the most crucial for us.

Thanks!!
