| 1 | =========== 3.2.5 |
|---|
| 2 | - PBSQuery |
|---|
| 3 | The class function of node, job and queue support old and new data structure. |
|---|
| 4 | Author: Bas van der Vlies |
|---|
| 5 | |
|---|
| 6 | =========== 3.2.0 |
|---|
| 7 | - PBSQuery: |
|---|
| 8 | New data structure. In the old structure it is a dictionary |
|---|
| 9 | with a value and the value is a string. This is changed |
|---|
| 10 | that dictionary values are now of type list or dictionary depends |
|---|
| 11 | on the value of the keyword, eg for a node: |
|---|
| 12 | - np = 2: |
|---|
| 13 | * node['np'] = [ '2' ] |
|---|
| 14 | |
|---|
| 15 | - properties = cores2, mem4gb, parallel |
|---|
| 16 | * node['properties'] = [ 'cores2', 'mem4gb', 'parallel' ] |
|---|
| 17 | |
|---|
| 18 | - status = arch=x86_64,sessions=22599,,size=70627864kb, ... |
|---|
| 19 | * node['status']['arch'] = [ 'x86_64' ] |
|---|
| 20 | * node['status']['sessions'] = [ '222599' ] |
|---|
| 21 | * ... |
|---|
| 22 | |
|---|
| 23 | The data structure is activated by the function: |
|---|
| 24 | * new_data_structure() |
|---|
| 25 | |
|---|
| 26 | In a future release it will be come the default. |
|---|
| 27 | example: |
|---|
| 28 | p = PBSQuery() |
|---|
| 29 | p.new_data_structure() |
|---|
| 30 | |
|---|
| 31 | nodes = p.getnodes() |
|---|
| 32 | print nodes.np, nodes['np'] |
|---|
| 33 | |
|---|
| 34 | Author: Bas van der Vlies |
|---|
| 35 | |
|---|
| 36 | - PBSQuery |
|---|
| 37 | For old and new data structure we now can use another syntax: |
|---|
| 38 | * node['np'] and node.np are equivalent |
|---|
| 39 | |
|---|
| 40 | This new syntax works for all keywords. |
|---|
| 41 | |
|---|
| 42 | Author: Bas van der Vlies |
|---|
| 43 | |
|---|
| 44 | - Added iter object for job, node, queue and server objects, eg: |
|---|
| 45 | node = p.getnode('gb-r1n1') |
|---|
| 46 | print node.name |
|---|
| 47 | for attrib in node: |
|---|
| 48 | print '%\t%s = %s' %(attrib, node[attrib]) |
|---|
| 49 | Author: Bas van der Vlies |
|---|
| 50 | |
|---|
| 51 | - fixed an error in getnode, getqueue and getjob, return empty |
|---|
| 52 | dictionary if not found |
|---|

|---|
| 65 | |
|---|
| 66 | =========== 3.0.0 |
|---|
| 67 | - PBSQuery |
|---|
| 68 | * Cleaned up some old lines of code which didn't do anything. |
|---|
| 69 | * Changed the returnvalue of getqueue, getnode and getjob. Now |
|---|
| 70 | they return an instance of the object, instead of a dict. |
|---|
| 71 | This is API change so we bumped the version to 3.0.0 |
|---|
| 72 | * Now the getnode-function accepts the short name as well as |
|---|
| 73 | the long name as an argument. |

|---|
| 102 | |
|---|
| 103 | - PBSQuery |
|---|
| 104 | * Added getnodes_with_property() function. This will get all nodes with |
|---|
| 105 | a certain property, eg: |

|---|
| 107 | getnodes_with_property('cores8') |
|---|
| 108 | |
|---|
| 109 | - get all nodes with property 'cores2' and only return the |
|---|
| 110 | attributes 'state' and 'properties': |
|---|
| 111 | attrl = [ 'state', 'properties' ] |
|---|
| 112 | getnodes_with_property('cores2', attrl) |
|---|
| 113 | |

|---|
| 214 | |
|---|
| 215 | =========== Version 2.7.10 |
|---|
| 216 | |
|---|
| 217 | PBSQuery.py: |
|---|
| 218 | Fixed an error. You always got all resources from eg nodes |
|---|
| 219 | even when you supplied an attribute list where you only |
|---|
| 220 | requested the 'state' of the node. |
|---|
| 221 | |
|---|
| 222 | Updated the inline python documentation |
|---|
| 223 | |
|---|
| 224 | =========== Version 2.7.9 |
|---|
| 225 | |
|---|
| 226 | Fixed an error the previous version was in DEBUG mode. So |
|---|
| 227 | you get an lot undesired output on the screen. |
|---|
| 228 | |
|---|
| 229 | debian package now also generated a package with the write |
|---|
| 230 | version info. |
|---|
| 231 | |
|---|
| 232 | =========== Version 2.7.8 |
|---|
| 233 | |
|---|
| 234 | Setup.py: |
|---|
| 235 | Can also handle ROCKS installations + the version |
|---|
| 236 | info is now the same as pbs.py |
|---|
| 237 | Thanks to: Roy Dragseth |
|---|
| 238 | |
|---|
| 239 | =========== Version 2.7.7 |
|---|
| 240 | |
|---|
| 241 | PBSQuery module: |
|---|
| 242 | It can now be used in daemon programs. The pbs_server closes |
|---|
| 243 | the connection after an certain amount of time. This is fixed, |
|---|
| 244 | before every query there is an new connection and if the query |
|---|
| 245 | is finished the connection is closed. |
|---|
| 246 | |
|---|
| 247 | =========== Version 2.7.6 |
|---|
| 248 | |
|---|
| 249 | Now setup.py can also handle old Oscar Installations. |
|---|
| 250 | Thanks To: Robin Humble |
|---|

| 252 | Fixed an print statement fix in new_interface.py: |
|---|
| 253 | Thanks To: Robin Humble |
|---|
| 254 | |
|---|
| 255 | Made some improvements for PBSQuery module: |
|---|
| 256 | - Updated the documentation |
|---|
| 257 | - Added the has_key() function to all |
|---|
| 258 | PBSObjects. So that the behaviour is similar to |
|---|
| 259 | an dictionary |

|---|
| 261 | |
|---|
| 262 | =========== Version 2.7.5 |
|---|
| 263 | Added PBSQuery module. This module requires pbs.py and it a simple module |
|---|
| 264 | for querying the pbs server. The documentation is in the module. Use for |
|---|
| 265 | example ipython to read it. |

|---|
| 303 | - Edit the rack_pbsmon.py to adjust the values. It requires |
|---|
| 304 | that hostname contains rack and node id's, |
|---|
| 305 | eg: gb-r<number>n<number> |

| 307 | |
|---|
| 308 | =========== Version 2.7.3 |
|---|
| 309 | The name SPBS is changed to the new name TORQUE (Tera-scale Open-source |
|---|
| 310 | Resource and QUEing manager). |
|---|
| 311 | |
|---|
| 312 | The interface support OPENPBS and TORQUE. |
|---|
| 313 | |
|---|
| 314 | =========== Version 2.7.2 |
|---|
| 315 | Some minor changes to include files. Now the Scalable PBS keywords |
|---|
| 316 | are also supported ( server attribute names: node_ping_rate and |
|---|
| 317 | node_check_rate). This does not interfere with the openpbs software. |
|---|
| 318 | |
|---|
| 319 | pbsmon.py could not handle an one node cluster. Fixed it. |
|---|
| 320 | |
|---|
| 321 | =========== Version 2.7 |
|---|
| 322 | Forgot to wrap the pbs_statfree() function. So we could not free |
|---|
| 323 | allocated memory from functions that return 'struct batch_status *' |
|---|
| 324 | like pbs_statjob(). |
|---|
| 325 | |
|---|
| 326 | pbsmon.py can now handle 2 and 3 digit hostnames. Patch supplied by |
|---|
| 327 | Daniel Olson |
|---|
| 328 | |
|---|
| 329 | =========== Version 2.6.1 |
|---|
| 330 | Setup.py now checks if all openpbs libraries are installed to compile the |
|---|
| 331 | package. |
|---|
| 332 | |
|---|
| 333 | =========== Version 2.6 |
|---|
| 334 | |
|---|
| 335 | Fixed a bug in the pbs python module. Forgot to map the pbs_statjob() |
|---|
| 336 | function. This bug prevented to pass 'struct attrl' variables to this |
|---|
| 337 | function. Thanks to Evelyn Shiu for reporting this bug. |
|---|
| 338 | |
|---|
| 339 | |
|---|
| 340 | =========== Version 2.5 |
|---|
| 341 | Added the OpenPbs logging functions (log.h and liblog.a). There |
|---|
| 342 | is an example in the examples directory: logpbs.py |
|---|
| 343 | |
|---|
| 344 | Fixed a bug in examples/resmom_info.py used the default port for |
|---|
| 345 | pbs_resmon if getservbyname fails. |
|---|
| 346 | |
|---|
| 347 | Fixed a bug in resmom code. If the user has no permissions to query |
|---|
| 348 | the pbs_mom daemon a empty string is returned. Now we check for |
|---|
| 349 | the empty string. So we do not get a python exception. |
|---|
| 350 | |
|---|
| 351 | Fixed a bug in setup.py forgot the exit statement when we did not |
|---|
| 352 | find the pbs libraries. |
|---|
| 353 | |
|---|
| 354 | =========== Version 2.3 |
|---|
| 355 | Bugfix in the pbsnodes-a.py. Forgot to import the sys module. |
|---|
| 356 | |
|---|
| 357 | Removed some obsolete code. |
|---|
| 358 | |
|---|
| 359 | As for now we make use of the distutils module. So the package |
|---|
| 360 | is automatically compiled and installed in proper directories, usage: |
|---|
| 361 | python setup.py install |
|---|
| 362 | This requires that the package 'distutils' must be installed. As for |
|---|
| 363 | version 1.6 and higher it is in the distribution. |
|---|
| 364 | |
|---|
| 365 | Added a function that prints the pbs python interface version. So we |
|---|
| 366 | can check if we have the right interface version: |
|---|
| 367 | import pbs |
|---|
| 368 | print pbs.version() |
|---|
| 369 | |
|---|
| 370 | |
|---|
| 371 | =========== Version 2.2 |
|---|
| 372 | |
|---|
| 373 | In this release we can query the pbs_mom daemon with the aid of |
|---|
| 374 | resource management functions: |
|---|
| 375 | pbs.openrm() |
|---|
| 376 | pbs.closerm() |
|---|
| 377 | pbs.downrm() |
|---|
| 378 | pbs.configrm() |
|---|
| 379 | pbs.addreq() |
|---|
| 380 | pbs.allreq() |
|---|
| 381 | pbs.flushreq() |
|---|
| 382 | pbs.activereq() |
|---|
| 383 | pbs.fullresp() |
|---|
| 384 | pbs.getreq() |
|---|
| 385 | |
|---|
| 386 | There is also a python function: |
|---|
| 387 | pbs.get_mom_values(id, [list]): |
|---|
| 388 | id - connection id of pbs.openrm(node-name, port-number) |
|---|
| 389 | list - Is a optional paramter. A list of resource keywords |
|---|
| 390 | |
|---|
| 391 | If 'list' is not supplied then this function will get the values |
|---|
| 392 | for the standard resource keywords, eg uname, loadave, .. + 'arch' |
|---|
| 393 | depended keywords. The arch feature is only implemented for linux, |
|---|
| 394 | but it can easily be ported to other oses. |
|---|
| 395 | |
|---|
| 396 | if 'list' is supplied then we only fetch values for the keywords |
|---|
| 397 | that are in the list. |
|---|
| 398 | |
|---|
| 399 | The function returns a dictonary. The keys are the resource keywords. |
|---|
| 400 | |
|---|
| 401 | See 'resmom_info.py' for a example of this new feature. |
|---|
| 402 | |
|---|

| 405 | The previous version was a simple interface above the PBS C API LIB. This |
|---|
| 406 | interface has gone a major changes. The most noticeable change is that |
|---|
| 407 | the functions accept/return Python lists instead of C-lists. So you can now |
|---|
| 408 | use standard Python syntax for manipulating Python lists. If you are familar |
|---|
| 409 | with the Python syntax then you will appreciate this new interface. |
|---|
| 410 | |
|---|
| 411 | NOTE: |
|---|
| 412 | This interface is NOT compatible with the old one |
|---|
| 413 | |
|---|
| 414 | Here are some guidelines to convert your code to the new one: |
|---|
| 415 | |
|---|
| 416 | The constructors for the struct has gone a major change: |
|---|
| 417 | old code: |
|---|
| 418 | temp = pbs.new_attrl(); |
|---|
| 419 | attrl_p = pbs.attrlPtr(temp) |
|---|
| 420 | attrl_p.name = 'state' |
|---|
| 421 | |
|---|
| 422 | new_code: |
|---|
| 423 | attr_l = pbs.new_attrl(1) // Creates a list of attrl structs length 1 |
|---|
| 424 | attr_l[0].name = 'state' |
|---|
| 425 | |
|---|
| 426 | |
|---|
| 427 | The pbs_stat functions returns Python lists instead of C-lists. There is |
|---|
| 428 | NO next field anymore: |
|---|
| 429 | old_code: |
|---|
| 430 | temp = pbs.new_attrl(); |
|---|
| 431 | attrl_p = pbs.attrlPtr(temp) |
|---|
| 432 | attrl_p.this = 'NULL' |
|---|
| 433 | |
|---|
| 434 | nodes = pbs.pbs_statnode(con, "", attrl_p, "NULL") |
|---|
| 435 | |
|---|
| 436 | while nodes.this != 'NULL': |
|---|
| 437 | print nodes.name |
|---|
| 438 | |
|---|
| 439 | node_attrl = nodes.attribs |
|---|
| 440 | while node_attrl.this != 'NULL': |
|---|
| 441 | print '\t', node_attrl.name, '=', node_attrl.value |
|---|
| 442 | node_attrl = node_attrl.next |
|---|
| 443 | |
|---|
| 444 | nodes = nodes.next |
|---|
| 445 | |
|---|
| 446 | |
|---|
| 447 | new_code: |
|---|
| 448 | nodes = pbs.pbs_statnode(con, "", "NULL", "NULL") |
|---|
| 449 | for node in nodes: |
|---|
| 450 | print node.name |
|---|
| 451 | for attrib in node.attribs: |
|---|
| 452 | print '\t', attrib.name, '=', attrib.value |
|---|
| 453 | |
|---|
| 454 | Another advantage is you can use the print statement to show the |
|---|
| 455 | connect of attrl and attropl classes: |
|---|
| 456 | attr_l = pbs.new_attrl(2) |
|---|
| 457 | attr_l[0].name = 'bas' |
|---|
| 458 | attr_l[0].value = 'van der Vlies' |
|---|
| 459 | |
|---|
| 460 | print attr_l[0] |
|---|
| 461 | >> (bas,,van der Vlies) |
|---|
| 462 | |
|---|
| 463 | I hope these examples illustrate the changes. If you specify a wrong type |
|---|
| 464 | for a function then function wil raise a Python exception. |
