invalid processes column in darshan-job-summary.pl variance table
Run a job in which a subset of the processes (more than 1, but less than all) open the same file and read or write data. The resulting variance table in the summary pdf will be off by one where it shows the number of processes that shared access to the file.
I'll attach an example (both the original .gz and the pdf). In this case the job had 8 processes, with 4 of them opening one file and 4 of them opening a different file. The variance table shows 3 processes for each.
