| 61 | Note: version 2.1.X is still supported |
---|
| 62 | |
---|
[217] | 63 | * autotools environment |
---|
| 64 | - Added support for finding pbs-config (borrowed for mpiexec source) |
---|
| 65 | - Detecting which version of torque is installed |
---|
| 66 | - only support installations that have pbs-config installed. |
---|
| 67 | - Removed old code for installations that do not a have pbs-config |
---|
| 68 | installed. |
---|
[214] | 69 | |
---|
[223] | 70 | * PBSQuery.py |

| 72 | Reported & Patch by: Mark Roberts ( mark at gingergeeks dot co dot uk) |
---|
| 73 | Applied by with some minor changes: Bas van der Vlies |
---|
| 74 | |
---|
| 75 | - The new data structure is the default. You can switch back to the old |
---|
| 76 | one with: |
---|
| 77 | p = PBSQuery() |
---|
| 78 | p.old_data_structure() |

---|
[205] | 91 | =========== 3.5.0 |
---|
| 92 | * PBSQuery |
---|
| 93 | The class functions of node, job and queue support old and new data |
---|
| 94 | structure. |
---|
[196] | 95 | |
---|
[205] | 96 | Changed the behaviour of the new data stucture, We can use it as |
---|
| 97 | dictionary and as class attribute, this is equivalent, eg: |
---|
| 98 | - print node['np'] and print node.np |
---|
| 99 | |
---|
| 100 | for a node we parse the 'status' line and split on '=' char, You now can |
---|
| 101 | use these statements, eg |
---|
| 102 | - print node.status.arch (node['status'].arch or node['status']['arch']) |
---|
| 103 | - print node.status.nsession |
---|
| 104 | |
---|
| 105 | for a job we parse the 'Variable_List' line and split on '=' char, You now can |
---|
| 106 | use the statements, eg: |
---|
| 107 | - print job.Variable_List.PBS_O_WORKDIR |
---|
| 108 | - print job.Variable_List.PBS_O_HOME |

| 114 | * new_rack_pbsmon.py |
---|
| 115 | Rewrite to new data structure and automatically determine how many nodes |
---|
| 116 | and racks cluster has and skip printing of empty racks (default), use -w/--wide |

---|
[189] | 122 | =========== 3.2.0 |
---|
| 123 | - PBSQuery: |
---|
| 124 | New data structure. In the old structure it is a dictionary |
---|
| 125 | with a value and the value is a string. This is changed |
---|
| 126 | that dictionary values are now of type list or dictionary depends |
---|
| 127 | on the value of the keyword, eg for a node: |
---|
| 128 | - np = 2: |
---|
| 129 | * node['np'] = [ '2' ] |
---|
| 130 | |
---|
| 131 | - properties = cores2, mem4gb, parallel |
---|
| 132 | * node['properties'] = [ 'cores2', 'mem4gb', 'parallel' ] |
---|
| 133 | |
---|
| 134 | - status = arch=x86_64,sessions=22599,,size=70627864kb, ... |
---|
| 135 | * node['status']['arch'] = [ 'x86_64' ] |
---|
| 136 | * node['status']['sessions'] = [ '222599' ] |
---|
| 137 | * ... |
---|
| 138 | |
---|
| 139 | The data structure is activated by the function: |
---|
| 140 | * new_data_structure() |
---|
| 141 | |
---|
| 142 | In a future release it will be come the default. |
---|
| 143 | example: |
---|
| 144 | p = PBSQuery() |
---|
| 145 | p.new_data_structure() |
---|
| 146 | |
---|
| 147 | nodes = p.getnodes() |
---|
| 148 | print nodes.np, nodes['np'] |
---|
| 149 | |
---|
| 150 | Author: Bas van der Vlies |
---|
| 151 | |
---|
| 152 | - PBSQuery |
---|
| 153 | For old and new data structure we now can use another syntax: |
---|
| 154 | * node['np'] and node.np are equivalent |
---|
| 155 | |
---|
| 156 | This new syntax works for all keywords. |
---|
| 157 | |
---|
| 158 | Author: Bas van der Vlies |
---|
[191] | 159 | |
---|
| 160 | - Added iter object for job, node, queue and server objects, eg: |
---|
| 161 | node = p.getnode('gb-r1n1') |
---|
| 162 | print node.name |
---|
| 163 | for attrib in node: |
---|
| 164 | print '%\t%s = %s' %(attrib, node[attrib]) |
---|
| 165 | Author: Bas van der Vlies |
---|
| 166 | |
---|
| 167 | - fixed an error in getnode, getqueue and getjob, return empty |
---|
| 168 | dictionary if not found |
---|

[175] | 182 | =========== 3.0.0 |
---|
| 183 | - PBSQuery |
---|
| 184 | * Cleaned up some old lines of code which didn't do anything. |
---|
| 185 | * Changed the returnvalue of getqueue, getnode and getjob. Now |
---|
| 186 | they return an instance of the object, instead of a dict. |
---|
[182] | 187 | This is API change so we bumped the version to 3.0.0 |
---|
[175] | 188 | * Now the getnode-function accepts the short name as well as |
---|
| 189 | the long name as an argument. |

---|
| 223 | getnodes_with_property('cores8') |
---|
| 224 | |
---|
| 225 | - get all nodes with property 'cores2' and only return the |

[85] | 331 | =========== Version 2.7.10 |
---|
| 332 | |
---|
| 333 | PBSQuery.py: |
---|
| 334 | Fixed an error. You always got all resources from eg nodes |
---|
| 335 | even when you supplied an attribute list where you only |
---|
| 336 | requested the 'state' of the node. |
---|
| 337 | |
---|
| 338 | Updated the inline python documentation |
---|
| 339 | |
---|
[82] | 340 | =========== Version 2.7.9 |
---|
| 341 | |
---|
| 342 | Fixed an error the previous version was in DEBUG mode. So |
---|
| 343 | you get an lot undesired output on the screen. |

---|
[78] | 356 | |
---|
[79] | 357 | PBSQuery module: |
---|
| 358 | It can now be used in daemon programs. The pbs_server closes |
---|
[80] | 359 | the connection after an certain amount of time. This is fixed, |
---|
| 360 | before every query there is an new connection and if the query |
---|
| 361 | is finished the connection is closed. |
---|
| 362 | |
---|
[79] | 363 | =========== Version 2.7.6 |

---|
| 372 | - Updated the documentation |
---|
| 373 | - Added the has_key() function to all |

[72] | 378 | =========== Version 2.7.5 |
---|
| 379 | Added PBSQuery module. This module requires pbs.py and it a simple module |
---|
[73] | 380 | for querying the pbs server. The documentation is in the module. Use for |
---|
| 381 | example ipython to read it. |

| 403 | Contributed By: Yaroslav Halchenko |
---|
| 404 | |
---|
| 405 | Added Support for Debuging the interface, You must edit pbs_wrap.c |
---|
| 406 | and search for SARA_DEBUG: |
---|
| 407 | #define SARA_DEBUG 1 |
---|
| 408 | Implemented by: Ramon Bastiaans |
---|
| 409 | |
---|
| 410 | examples/pbsmon.py: |
---|
| 411 | - Fixed an error when regex fails to determine node number, |
---|
| 412 | no status was displayed |
---|
| 413 | - It will now display and 'j' if the node is free for the batch |
---|
| 414 | system and a job runs on the node (SMP-systems). |
---|
| 415 | Changed by: Bas van der Vlies |
---|
| 416 | |
---|
| 417 | examples/rack_pbsmon.py: |
---|
| 418 | - An pbsmon that display node info per rack |
---|
| 419 | - Edit the rack_pbsmon.py to adjust the values. It requires |
---|
| 420 | that hostname contains rack and node id's, |
---|
| 421 | eg: gb-r<number>n<number> |
---|

---|
| 423 | |
---|
[58] | 424 | =========== Version 2.7.3 |
---|
| 425 | The name SPBS is changed to the new name TORQUE (Tera-scale Open-source |
---|
| 426 | Resource and QUEing manager). |
---|
| 427 | |
---|
| 428 | The interface support OPENPBS and TORQUE. |
---|
| 429 | |
---|
[52] | 430 | =========== Version 2.7.2 |
---|
| 431 | Some minor changes to include files. Now the Scalable PBS keywords |
---|
| 432 | are also supported ( server attribute names: node_ping_rate and |
---|
| 433 | node_check_rate). This does not interfere with the openpbs software. |
---|
| 434 | |
---|
[55] | 435 | pbsmon.py could not handle an one node cluster. Fixed it. |
---|
[52] | 436 | |
---|
[51] | 437 | =========== Version 2.7 |
---|
| 438 | Forgot to wrap the pbs_statfree() function. So we could not free |
---|
| 439 | allocated memory from functions that return 'struct batch_status *' |
---|
| 440 | like pbs_statjob(). |
---|
| 441 | |
---|
[48] | 442 | pbsmon.py can now handle 2 and 3 digit hostnames. Patch supplied by |
---|
[47] | 443 | Daniel Olson |
---|
| 444 | |
---|
[43] | 445 | =========== Version 2.6.1 |
---|
| 446 | Setup.py now checks if all openpbs libraries are installed to compile the |
---|
| 447 | package. |
---|
| 448 | |
---|
[34] | 449 | =========== Version 2.6 |
---|
| 450 | |
---|
| 451 | Fixed a bug in the pbs python module. Forgot to map the pbs_statjob() |
---|
| 452 | function. This bug prevented to pass 'struct attrl' variables to this |
---|
[35] | 453 | function. Thanks to Evelyn Shiu for reporting this bug. |
---|
[34] | 454 | |
---|
| 455 | |
---|
[26] | 456 | =========== Version 2.5 |
---|
| 457 | Added the OpenPbs logging functions (log.h and liblog.a). There |
---|
| 458 | is an example in the examples directory: logpbs.py |
---|
| 459 | |
---|
[33] | 460 | Fixed a bug in examples/resmom_info.py used the default port for |
---|
| 461 | pbs_resmon if getservbyname fails. |
---|
[28] | 462 | |
---|
| 463 | Fixed a bug in resmom code. If the user has no permissions to query |
---|
| 464 | the pbs_mom daemon a empty string is returned. Now we check for |
---|
| 465 | the empty string. So we do not get a python exception. |
---|
| 466 | |
---|
[30] | 467 | Fixed a bug in setup.py forgot the exit statement when we did not |
---|
| 468 | find the pbs libraries. |
---|
| 469 | |
---|
[22] | 470 | =========== Version 2.3 |
---|
[20] | 471 | Bugfix in the pbsnodes-a.py. Forgot to import the sys module. |
---|
| 472 | |
---|
[21] | 473 | Removed some obsolete code. |
---|
[20] | 474 | |
---|
| 475 | As for now we make use of the distutils module. So the package |
---|
| 476 | is automatically compiled and installed in proper directories, usage: |
---|
| 477 | python setup.py install |
---|
[21] | 478 | This requires that the package 'distutils' must be installed. As for |
---|
[22] | 479 | version 1.6 and higher it is in the distribution. |
---|
[20] | 480 | |
---|
[24] | 481 | Added a function that prints the pbs python interface version. So we |
---|
| 482 | can check if we have the right interface version: |
---|
| 483 | import pbs |
---|
| 484 | print pbs.version() |
---|
| 485 | |
---|
| 486 | |
---|
[11] | 487 | =========== Version 2.2 |
---|
| 488 | |
---|
| 489 | In this release we can query the pbs_mom daemon with the aid of |
---|
| 490 | resource management functions: |
---|
| 491 | pbs.openrm() |
---|
| 492 | pbs.closerm() |
---|
| 493 | pbs.downrm() |
---|
| 494 | pbs.configrm() |
---|
| 495 | pbs.addreq() |
---|
| 496 | pbs.allreq() |
---|
| 497 | pbs.flushreq() |
---|
| 498 | pbs.activereq() |
---|
| 499 | pbs.fullresp() |
---|
| 500 | pbs.getreq() |
---|
| 501 | |
---|
| 502 | There is also a python function: |
---|
| 503 | pbs.get_mom_values(id, [list]): |
---|
| 504 | id - connection id of pbs.openrm(node-name, port-number) |
---|
| 505 | list - Is a optional paramter. A list of resource keywords |
---|
| 506 | |
---|
| 507 | If 'list' is not supplied then this function will get the values |
---|
[19] | 508 | for the standard resource keywords, eg uname, loadave, .. + 'arch' |
---|
| 509 | depended keywords. The arch feature is only implemented for linux, |
---|
| 510 | but it can easily be ported to other oses. |
---|
[11] | 511 | |
---|
| 512 | if 'list' is supplied then we only fetch values for the keywords |
---|
| 513 | that are in the list. |
---|
| 514 | |
---|
| 515 | The function returns a dictonary. The keys are the resource keywords. |
---|
| 516 | |
---|
[19] | 517 | See 'resmom_info.py' for a example of this new feature. |
---|
[11] | 518 | |
---|
| 519 | =========== Version 2.0 |
---|
| 520 | |
---|
[8] | 521 | The previous version was a simple interface above the PBS C API LIB. This |
---|
| 522 | interface has gone a major changes. The most noticeable change is that |
---|
| 523 | the functions accept/return Python lists instead of C-lists. So you can now |
---|
| 524 | use standard Python syntax for manipulating Python lists. If you are familar |
---|
| 525 | with the Python syntax then you will appreciate this new interface. |
---|
| 526 | |
---|
| 527 | NOTE: |
---|
| 528 | This interface is NOT compatible with the old one |
---|
| 529 | |
---|
| 530 | Here are some guidelines to convert your code to the new one: |
---|
| 531 | |
---|
| 532 | The constructors for the struct has gone a major change: |
---|
| 533 | old code: |
---|
| 534 | temp = pbs.new_attrl(); |
---|
| 535 | attrl_p = pbs.attrlPtr(temp) |
---|
| 536 | attrl_p.name = 'state' |
---|
| 537 | |
---|
| 538 | new_code: |
---|
| 539 | attr_l = pbs.new_attrl(1) // Creates a list of attrl structs length 1 |
---|
| 540 | attr_l[0].name = 'state' |
---|
| 541 | |
---|
| 542 | |
---|
| 543 | The pbs_stat functions returns Python lists instead of C-lists. There is |
---|
| 544 | NO next field anymore: |
---|
| 545 | old_code: |
---|
| 546 | temp = pbs.new_attrl(); |
---|
| 547 | attrl_p = pbs.attrlPtr(temp) |
---|
| 548 | attrl_p.this = 'NULL' |
---|
| 549 | |
---|
| 550 | nodes = pbs.pbs_statnode(con, "", attrl_p, "NULL") |
---|
| 551 | |
---|
| 552 | while nodes.this != 'NULL': |
---|
| 553 | print nodes.name |
---|
| 554 | |
---|
| 555 | node_attrl = nodes.attribs |
---|
| 556 | while node_attrl.this != 'NULL': |
---|
| 557 | print '\t', node_attrl.name, '=', node_attrl.value |
---|
| 558 | node_attrl = node_attrl.next |
---|
| 559 | |
---|
| 560 | nodes = nodes.next |
---|
| 561 | |
---|
| 562 | |
---|
| 563 | new_code: |
---|
| 564 | nodes = pbs.pbs_statnode(con, "", "NULL", "NULL") |
---|
| 565 | for node in nodes: |
---|
| 566 | print node.name |
---|
| 567 | for attrib in node.attribs: |
---|
| 568 | print '\t', attrib.name, '=', attrib.value |
---|
| 569 | |
---|
| 570 | Another advantage is you can use the print statement to show the |
---|
| 571 | connect of attrl and attropl classes: |
---|
| 572 | attr_l = pbs.new_attrl(2) |
---|
| 573 | attr_l[0].name = 'bas' |
---|
| 574 | attr_l[0].value = 'van der Vlies' |
---|
| 575 | |
---|
| 576 | print attr_l[0] |
---|
| 577 | >> (bas,,van der Vlies) |
---|
| 578 | |
---|
| 579 | I hope these examples illustrate the changes. If you specify a wrong type |
---|
| 580 | for a function then function wil raise a Python exception. |
