1 | =========== Version 2.7.2 |
---|
2 | Some minor changes to include files. Now the Scalable PBS keywords |
---|
3 | are also supported ( server attribute names: node_ping_rate and |
---|
4 | node_check_rate). This does not interfere with the openpbs software. |
---|
5 | |
---|
6 | |
---|
7 | =========== Version 2.7 |
---|
8 | Forgot to wrap the pbs_statfree() function. So we could not free |
---|
9 | allocated memory from functions that return 'struct batch_status *' |
---|
10 | like pbs_statjob(). |
---|
11 | |
---|
12 | pbsmon.py can now handle 2 and 3 digit hostnames. Patch supplied by |
---|
13 | Daniel Olson |
---|
14 | |
---|
15 | =========== Version 2.6.1 |
---|
16 | Setup.py now checks if all openpbs libraries are installed to compile the |
---|
17 | package. |
---|
18 | |
---|
19 | =========== Version 2.6 |
---|
20 | |
---|
21 | Fixed a bug in the pbs python module. Forgot to map the pbs_statjob() |
---|
22 | function. This bug prevented to pass 'struct attrl' variables to this |
---|
23 | function. Thanks to Evelyn Shiu for reporting this bug. |
---|
24 | |
---|
25 | |
---|
26 | =========== Version 2.5 |
---|
27 | Added the OpenPbs logging functions (log.h and liblog.a). There |
---|
28 | is an example in the examples directory: logpbs.py |
---|
29 | |
---|
30 | Fixed a bug in examples/resmom_info.py used the default port for |
---|
31 | pbs_resmon if getservbyname fails. |
---|
32 | |
---|
33 | Fixed a bug in resmom code. If the user has no permissions to query |
---|
34 | the pbs_mom daemon a empty string is returned. Now we check for |
---|
35 | the empty string. So we do not get a python exception. |
---|
36 | |
---|
37 | Fixed a bug in setup.py forgot the exit statement when we did not |
---|
38 | find the pbs libraries. |
---|
39 | |
---|
40 | =========== Version 2.3 |
---|
41 | Bugfix in the pbsnodes-a.py. Forgot to import the sys module. |
---|
42 | |
---|
43 | Removed some obsolete code. |
---|
44 | |
---|
45 | As for now we make use of the distutils module. So the package |
---|
46 | is automatically compiled and installed in proper directories, usage: |
---|
47 | python setup.py install |
---|
48 | This requires that the package 'distutils' must be installed. As for |
---|
49 | version 1.6 and higher it is in the distribution. |
---|
50 | |
---|
51 | Added a function that prints the pbs python interface version. So we |
---|
52 | can check if we have the right interface version: |
---|
53 | import pbs |
---|
54 | print pbs.version() |
---|
55 | |
---|
56 | |
---|
57 | =========== Version 2.2 |
---|
58 | |
---|
59 | In this release we can query the pbs_mom daemon with the aid of |
---|
60 | resource management functions: |
---|
61 | pbs.openrm() |
---|
62 | pbs.closerm() |
---|
63 | pbs.downrm() |
---|
64 | pbs.configrm() |
---|
65 | pbs.addreq() |
---|
66 | pbs.allreq() |
---|
67 | pbs.flushreq() |
---|
68 | pbs.activereq() |
---|
69 | pbs.fullresp() |
---|
70 | pbs.getreq() |
---|
71 | |
---|
72 | There is also a python function: |
---|
73 | pbs.get_mom_values(id, [list]): |
---|
74 | id - connection id of pbs.openrm(node-name, port-number) |
---|
75 | list - Is a optional paramter. A list of resource keywords |
---|
76 | |
---|
77 | If 'list' is not supplied then this function will get the values |
---|
78 | for the standard resource keywords, eg uname, loadave, .. + 'arch' |
---|
79 | depended keywords. The arch feature is only implemented for linux, |
---|
80 | but it can easily be ported to other oses. |
---|
81 | |
---|
82 | if 'list' is supplied then we only fetch values for the keywords |
---|
83 | that are in the list. |
---|
84 | |
---|
85 | The function returns a dictonary. The keys are the resource keywords. |
---|
86 | |
---|
87 | See 'resmom_info.py' for a example of this new feature. |
---|
88 | |
---|
89 | =========== Version 2.0 |
---|
90 | |
---|
91 | The previous version was a simple interface above the PBS C API LIB. This |
---|
92 | interface has gone a major changes. The most noticeable change is that |
---|
93 | the functions accept/return Python lists instead of C-lists. So you can now |
---|
94 | use standard Python syntax for manipulating Python lists. If you are familar |
---|
95 | with the Python syntax then you will appreciate this new interface. |
---|
96 | |
---|
97 | NOTE: |
---|
98 | This interface is NOT compatible with the old one |
---|
99 | |
---|
100 | Here are some guidelines to convert your code to the new one: |
---|
101 | |
---|
102 | The constructors for the struct has gone a major change: |
---|
103 | old code: |
---|
104 | temp = pbs.new_attrl(); |
---|
105 | attrl_p = pbs.attrlPtr(temp) |
---|
106 | attrl_p.name = 'state' |
---|
107 | |
---|
108 | new_code: |
---|
109 | attr_l = pbs.new_attrl(1) // Creates a list of attrl structs length 1 |
---|
110 | attr_l[0].name = 'state' |
---|
111 | |
---|
112 | |
---|
113 | The pbs_stat functions returns Python lists instead of C-lists. There is |
---|
114 | NO next field anymore: |
---|
115 | old_code: |
---|
116 | temp = pbs.new_attrl(); |
---|
117 | attrl_p = pbs.attrlPtr(temp) |
---|
118 | attrl_p.this = 'NULL' |
---|
119 | |
---|
120 | nodes = pbs.pbs_statnode(con, "", attrl_p, "NULL") |
---|
121 | |
---|
122 | while nodes.this != 'NULL': |
---|
123 | print nodes.name |
---|
124 | |
---|
125 | node_attrl = nodes.attribs |
---|
126 | while node_attrl.this != 'NULL': |
---|
127 | print '\t', node_attrl.name, '=', node_attrl.value |
---|
128 | node_attrl = node_attrl.next |
---|
129 | |
---|
130 | nodes = nodes.next |
---|
131 | |
---|
132 | |
---|
133 | new_code: |
---|
134 | nodes = pbs.pbs_statnode(con, "", "NULL", "NULL") |
---|
135 | for node in nodes: |
---|
136 | print node.name |
---|
137 | for attrib in node.attribs: |
---|
138 | print '\t', attrib.name, '=', attrib.value |
---|
139 | |
---|
140 | Another advantage is you can use the print statement to show the |
---|
141 | connect of attrl and attropl classes: |
---|
142 | attr_l = pbs.new_attrl(2) |
---|
143 | attr_l[0].name = 'bas' |
---|
144 | attr_l[0].value = 'van der Vlies' |
---|
145 | |
---|
146 | print attr_l[0] |
---|
147 | >> (bas,,van der Vlies) |
---|
148 | |
---|
149 | I hope these examples illustrate the changes. If you specify a wrong type |
---|
150 | for a function then function wil raise a Python exception. |
