| 21 | /** | |
| 22 | * Converts PBS XML file to UsageRecord GGF WG format. Before the | |
| 23 | * conversion is done this program will insert two elements: | |
| 24 | * /pbs_jobfile/ppn -- the number of processors on each node. | |
| 25 | * /pbs_jobfile/machine_name -- the name of the machine. This should | |
| 26 | * be the same as the URWG MachineName element. | |
| 27 | * | |
| 28 | * <p> | |
| 29 | * Additionally, the timestamps will be converted from epoch time to | |
| 30 | * xsd:dateTime format. This is done for the elements: ctime, etime, | |
| 31 | * qtime, start, end. Each of these elements will be restructured as: | |
| 32 | * <time_element>/epoch -- The value in epoch time | |
| 33 | * <time_element>/datetime -- the value in xsd:dateTime format. | |
| 34 | * | |
| 35 | * <p> | |
| 36 | * Further, the <nodegroup> elements will have an extra attribute | |
| 37 | * added called 'processors' which is the product of the numnodes | |
| 38 | * attribute and ppn (the attribute or the default value if the | |
| 39 | * attribute is not present). | |
| 40 | * | |
| 41 | * <p> | |
| 42 | * Note this borrowed heavily from PbsToJoblog.java. | |
| 43 | * | |
| 44 | * The usage is | |
| 45 | * <pre> | |
| 46 | * java umich.cac.xml.PbsToGrid <pbs xml file> <output file> | |
| 47 | * <machine name> <ppn> | |
