1 | =========== Version 2.7.10 |
---|
2 | |
---|
3 | PBSQuery.py: |
---|
4 | Fixed an error. You always got all resources from eg nodes |
---|
5 | even when you supplied an attribute list where you only |
---|
6 | requested the 'state' of the node. |
---|
7 | |
---|
8 | Updated the inline python documentation |
---|
9 | |
---|
10 | =========== Version 2.7.9 |
---|
11 | |
---|
12 | Fixed an error the previous version was in DEBUG mode. So |
---|
13 | you get an lot undesired output on the screen. |
---|
14 | |
---|
15 | debian package now also generated a package with the write |
---|
16 | version info. |
---|
17 | |
---|
18 | =========== Version 2.7.8 |
---|
19 | |
---|
20 | Setup.py: |
---|
21 | Can also handle ROCKS installations + the version |
---|
22 | info is now the same as pbs.py |
---|
23 | Thanks to: Roy Dragseth |
---|
24 | |
---|
25 | =========== Version 2.7.7 |
---|
26 | |
---|
27 | PBSQuery module: |
---|
28 | It can now be used in daemon programs. The pbs_server closes |
---|
29 | the connection after an certain amount of time. This is fixed, |
---|
30 | before every query there is an new connection and if the query |
---|
31 | is finished the connection is closed. |
---|
32 | |
---|
33 | =========== Version 2.7.6 |
---|
34 | |
---|
35 | Now setup.py can also handle old Oscar Installations. |
---|
36 | Thanks To: Robin Humble |
---|
37 | |
---|
38 | Fixed an print statement fix in new_interface.py: |
---|
39 | Thanks To: Robin Humble |
---|
40 | |
---|
41 | Made some improvements for PBSQuery module: |
---|
42 | - Updated the documentation |
---|
43 | - Added the has_key() function to all |
---|
44 | PBSObjects. So that the behaviour is similar to |
---|
45 | an dictionary |
---|
46 | Suggested By: Ramon Bastiaans |
---|
47 | |
---|
48 | =========== Version 2.7.5 |
---|
49 | Added PBSQuery module. This module requires pbs.py and it a simple module |
---|
50 | for querying the pbs server. The documentation is in the module. Use for |
---|
51 | example ipython to read it. |

73 | Contributed By: Yaroslav Halchenko |
---|
74 | |
---|
75 | Added Support for Debuging the interface, You must edit pbs_wrap.c |
---|
76 | and search for SARA_DEBUG: |
---|
77 | #define SARA_DEBUG 1 |
---|
78 | Implemented by: Ramon Bastiaans |
---|
79 | |
---|
80 | examples/pbsmon.py: |
---|
81 | - Fixed an error when regex fails to determine node number, |
---|
82 | no status was displayed |
---|
83 | - It will now display and 'j' if the node is free for the batch |
---|
84 | system and a job runs on the node (SMP-systems). |
---|
85 | Changed by: Bas van der Vlies |
---|
86 | |
---|
87 | examples/rack_pbsmon.py: |
---|
88 | - An pbsmon that display node info per rack |
---|
89 | - Edit the rack_pbsmon.py to adjust the values. It requires |
---|
90 | that hostname contains rack and node id's, |
---|
91 | eg: gb-r<number>n<number> |
---|
92 | Contributed by: Walter de Jong |
---|
93 | |
---|
94 | =========== Version 2.7.3 |
---|
95 | The name SPBS is changed to the new name TORQUE (Tera-scale Open-source |
---|
96 | Resource and QUEing manager). |
---|
97 | |
---|
98 | The interface support OPENPBS and TORQUE. |
---|
99 | |
---|
100 | =========== Version 2.7.2 |
---|
101 | Some minor changes to include files. Now the Scalable PBS keywords |
---|
102 | are also supported ( server attribute names: node_ping_rate and |
---|
103 | node_check_rate). This does not interfere with the openpbs software. |
---|
104 | |
---|
105 | pbsmon.py could not handle an one node cluster. Fixed it. |
---|
106 | |
---|
107 | =========== Version 2.7 |
---|
108 | Forgot to wrap the pbs_statfree() function. So we could not free |
---|
109 | allocated memory from functions that return 'struct batch_status *' |
---|
110 | like pbs_statjob(). |
---|
111 | |
---|
112 | pbsmon.py can now handle 2 and 3 digit hostnames. Patch supplied by |
---|
113 | Daniel Olson |
---|
114 | |
---|
115 | =========== Version 2.6.1 |
---|
116 | Setup.py now checks if all openpbs libraries are installed to compile the |
---|
117 | package. |
---|
118 | |
---|
119 | =========== Version 2.6 |
---|
120 | |
---|
121 | Fixed a bug in the pbs python module. Forgot to map the pbs_statjob() |
---|
122 | function. This bug prevented to pass 'struct attrl' variables to this |
---|
123 | function. Thanks to Evelyn Shiu for reporting this bug. |
---|
124 | |
---|
125 | |
---|
126 | =========== Version 2.5 |
---|
127 | Added the OpenPbs logging functions (log.h and liblog.a). There |
---|
128 | is an example in the examples directory: logpbs.py |
---|
129 | |
---|
130 | Fixed a bug in examples/resmom_info.py used the default port for |
---|
131 | pbs_resmon if getservbyname fails. |
---|
132 | |
---|
133 | Fixed a bug in resmom code. If the user has no permissions to query |
---|
134 | the pbs_mom daemon a empty string is returned. Now we check for |
---|
135 | the empty string. So we do not get a python exception. |
---|
136 | |
---|
137 | Fixed a bug in setup.py forgot the exit statement when we did not |
---|
138 | find the pbs libraries. |
---|
139 | |
---|
140 | =========== Version 2.3 |
---|
141 | Bugfix in the pbsnodes-a.py. Forgot to import the sys module. |
---|
142 | |
---|
143 | Removed some obsolete code. |
---|
144 | |
---|
145 | As for now we make use of the distutils module. So the package |
---|
146 | is automatically compiled and installed in proper directories, usage: |
---|
147 | python setup.py install |
---|
148 | This requires that the package 'distutils' must be installed. As for |
---|
149 | version 1.6 and higher it is in the distribution. |
---|
150 | |
---|
151 | Added a function that prints the pbs python interface version. So we |
---|
152 | can check if we have the right interface version: |
---|
153 | import pbs |
---|
154 | print pbs.version() |
---|
155 | |
---|
156 | |
---|
157 | =========== Version 2.2 |
---|
158 | |
---|
159 | In this release we can query the pbs_mom daemon with the aid of |
---|
160 | resource management functions: |
---|
161 | pbs.openrm() |
---|
162 | pbs.closerm() |
---|
163 | pbs.downrm() |
---|
164 | pbs.configrm() |
---|
165 | pbs.addreq() |
---|
166 | pbs.allreq() |
---|
167 | pbs.flushreq() |
---|
168 | pbs.activereq() |
---|
169 | pbs.fullresp() |
---|
170 | pbs.getreq() |
---|
171 | |
---|
172 | There is also a python function: |
---|
173 | pbs.get_mom_values(id, [list]): |
---|
174 | id - connection id of pbs.openrm(node-name, port-number) |
---|
175 | list - Is a optional paramter. A list of resource keywords |
---|
176 | |
---|
177 | If 'list' is not supplied then this function will get the values |
---|
178 | for the standard resource keywords, eg uname, loadave, .. + 'arch' |
---|
179 | depended keywords. The arch feature is only implemented for linux, |
---|
180 | but it can easily be ported to other oses. |
---|
181 | |
---|
182 | if 'list' is supplied then we only fetch values for the keywords |
---|
183 | that are in the list. |
---|
184 | |
---|
185 | The function returns a dictonary. The keys are the resource keywords. |
---|
186 | |
---|
187 | See 'resmom_info.py' for a example of this new feature. |
---|
188 | |
---|
189 | =========== Version 2.0 |
---|
190 | |
---|
191 | The previous version was a simple interface above the PBS C API LIB. This |
---|
192 | interface has gone a major changes. The most noticeable change is that |
---|
193 | the functions accept/return Python lists instead of C-lists. So you can now |
---|
194 | use standard Python syntax for manipulating Python lists. If you are familar |
---|
195 | with the Python syntax then you will appreciate this new interface. |
---|
196 | |
---|
197 | NOTE: |
---|
198 | This interface is NOT compatible with the old one |
---|
199 | |
---|
200 | Here are some guidelines to convert your code to the new one: |
---|
201 | |
---|
202 | The constructors for the struct has gone a major change: |
---|
203 | old code: |
---|
204 | temp = pbs.new_attrl(); |
---|
205 | attrl_p = pbs.attrlPtr(temp) |
---|
206 | attrl_p.name = 'state' |
---|
207 | |
---|
208 | new_code: |
---|
209 | attr_l = pbs.new_attrl(1) // Creates a list of attrl structs length 1 |
---|
210 | attr_l[0].name = 'state' |
---|
211 | |
---|
212 | |
---|
213 | The pbs_stat functions returns Python lists instead of C-lists. There is |
---|
214 | NO next field anymore: |
---|
215 | old_code: |
---|
216 | temp = pbs.new_attrl(); |
---|
217 | attrl_p = pbs.attrlPtr(temp) |
---|
218 | attrl_p.this = 'NULL' |
---|
219 | |
---|
220 | nodes = pbs.pbs_statnode(con, "", attrl_p, "NULL") |
---|
221 | |
---|
222 | while nodes.this != 'NULL': |
---|
223 | print nodes.name |
---|
224 | |
---|
225 | node_attrl = nodes.attribs |
---|
226 | while node_attrl.this != 'NULL': |
---|
227 | print '\t', node_attrl.name, '=', node_attrl.value |
---|
228 | node_attrl = node_attrl.next |
---|
229 | |
---|
230 | nodes = nodes.next |
---|
231 | |
---|
232 | |
---|
233 | new_code: |
---|
234 | nodes = pbs.pbs_statnode(con, "", "NULL", "NULL") |
---|
235 | for node in nodes: |
---|
236 | print node.name |
---|
237 | for attrib in node.attribs: |
---|
238 | print '\t', attrib.name, '=', attrib.value |
---|
239 | |
---|
240 | Another advantage is you can use the print statement to show the |
---|
241 | connect of attrl and attropl classes: |
---|
242 | attr_l = pbs.new_attrl(2) |
---|
243 | attr_l[0].name = 'bas' |
---|
244 | attr_l[0].value = 'van der Vlies' |
---|
245 | |
---|
246 | print attr_l[0] |
---|
247 | >> (bas,,van der Vlies) |
---|
248 | |
---|
249 | I hope these examples illustrate the changes. If you specify a wrong type |
---|
250 | for a function then function wil raise a Python exception. |
