What we've typically done in the past is cross-reference the job ID reported by Darshan against scheduler databases/logs to get this information. thanks, -Phil

Hi, Is there a way of finding the job's compute nodes with the *darshan-parser *command? If not, is there another way? Thanks again, COS

darshan-parser --file

Hi, When using the "--file" flag for the darshan-parser tool, I was a little unsure about what certain figures meant. Under "files" in the POSIX/MPIIO sections, what do the three figures following "total", "read_only", "write_only" (etc.) mean? Example: # ******************************************************* # POSIX module data # ******************************************************* # files # ----- # total: 15 404420357 201111068 # read_only: 4 203309289 201111068 # write_only: 1 201111068 201111068 # read_write: 0 0 0 # unique: 13 203309289 201111068 # shared: 2 201111068 201111068 For "total", what do the "15 404420357 201111068" mean? Thanks, Colm
