25 | 3. *** Architecture of GIMI tools for GEC14 tutorial
|
---|
26 |
|
---|
27 | a) (Mike) need to arrive at nominal configuration ASAP
|
---|
28 |
|
---|
29 | on 4/18: good discussion (see below); still need a clear and complete description soon; when? 5/2? earlier?
|
---|
30 |
|
---|
31 | a') on 4/20: issue: how to configure tools? from EC to RC in tool?
|
---|
32 |
|
---|
33 | a'') on 4/20: issue: is there a MAP on common node? at least to preview data? is there a MAP in user workspace? what?
|
---|
34 |
|
---|
35 | b) MPs with multiple possible measurements: host info; basic network performance with iperf, ping; data from app
|
---|
36 |
|
---|
37 | c) MC (OML server) in common node (node n+1)
|
---|
38 |
|
---|
39 | d) where is MAP service installed? in common node? in user workspace? what is planned for this service? how can analysis/presentation be configured? is there an r script? is there a GUI? how is GUI accessed?
|
---|
40 |
|
---|
41 | e) movement of data from MC (OML server) to MAP service: direct? how? via iRODS, i.e., MC to iRODS to MAP? how?
|
---|
42 |
|
---|
43 | e') on 4/18, per Shu, and discussion: could login to MC node; establish first transfer from iRODS client on MC to to iRODS with iput; use iinit, so iRODS client remembers password; then periodic transfers with no human intervention; another push protocol, from MC to iRODS.
|
---|
44 |
|
---|
45 | e'') on 4/18, per Shu, and discussion: next, can install iRODS client on user workspace, then pull data back to user workspace for analysis and presentation, and then push back to iRODS for archive
|
---|
46 |
|
---|
47 | f) 1st: common node in slice; 2nd: common node in user workspace (out of slice) (is this beyond GEC14?)
|
---|
48 |
|
---|
49 | g) 1st: nodes on VMs, one aggregate; 2nd: nodes on VMs, multiple aggregates
|
---|
50 |
|
---|
51 | h) 1st: Load image for common node, MP nodes; 2nd: load MP code as package before/after app what is test app?
|
---|
52 |
|
---|
53 | i) Is there authentication/authorization when data pushed fom MP to MC? 1st: none; considered OK 2nd: add ssl?
|
---|
54 |
|
---|
55 | j) Is there authentication/authorization when accessing GUI (MAP) on common node? how? does this use portal to GUIs?
|
---|
56 |
|
---|
57 |
|
---|
58 | 4. *** Introduce XML messaging service: required for OMF messages, used to orchestrate services
|

60 | a) (Max, Christoph) public XMPP server must be available; what? where?
|
---|
61 |
|
---|
62 | b) (Max, Christoph) signed OMF messages: need summary of arrangement from NICTA. what are names? who configures pub/sub nodes? what is structure? how to generate and distribute keys? is a public key registry required? how would it be done?
|
---|
63 |
|
---|
64 | On 4/18: Max explains plan to use OMF6.0 approach; limited messages; can use XMPP or another transport; signed messages; can start with no authentication/authorization, and then turn it on later;
|
---|
65 |
|
---|
66 | b') On 4/18: need clear and complete description soon, particularly naming and establsihment of XMPP nodes. so that others can consider for use and Jeanne can begin testing.
|
---|
67 |
|
---|
68 | b'') On 4/18: expect release of first OMF6.0 by mid-May, with firm RC and skeleton EC; expect updated EC by mid-June; is this too late for GEC14?

72 | a) includes stores for keys, certificates, credentials, rspecs
|
---|
73 |
|
---|
74 | b) (Jeanne A, David) Use Gush with OMNI to acquire resources, load images/packages, setup connectivity, manage processes
|
---|
75 |
|
---|
76 | c) (Christoph) Use OMF EC to configure/orchestrate services can EC drive scripts?
|

|
---|
106 | use iRODS cleint in MC to push to iRODS? how is authentication/authorization handled?
|
---|
107 | use iRODS client in user workspace to pull to user workspace? how is authentication/authorization handled?
|
---|
108 |
|
---|
109 | On 4/18: use cases received:
|
---|
110 |
|
---|
111 | GIMI iRODS Use Cases - Preparation
|
---|
112 |
|
---|
113 | Create an account for user: shuang
|
---|
114 | iadmin mkuser shuang user_type
|
---|
115 | Assign user to a group
|
---|
116 | iadmin atg groupName shuang
|
---|
117 | Admin can assign password to user (also supports GSI/Kerberos)
|
---|
118 | iadmin moduser shuang password xxx
|
---|
119 | A lot of other things can be done:
|
---|
120 | iadmin h
|
---|
121 | Create an iRODS directory for the user OML measurement data
|
---|
122 | imkdir results
|
---|
123 |
|
---|
124 | GIMI iRODS Use Case 1
|
---|
125 | Perform an OML-based measurement, result is saved in a file (a.sqlite3) under /home/shuang/results
|
---|
126 | Put the file into iRODS
|
---|
127 | iput a.sqlite3 (suppose ipwd is /geniRenci/home/shuang/results)
|
---|
128 | Work on the local copy under /home/shuang/results
|
---|
129 | Push the modified file back into iRODS (think it as a version control system)
|
---|
130 | Irsync r /home/shuang/result i:/geniRenci/home/shuang/results
|
---|
131 |
|
---|
132 | GIMI iRODS Use Case 2
|
---|
133 | Check out a file in iRODS to my local directory
|
---|
134 | iget a.sqlite3
|
---|
135 | Work on the local copy
|
---|
136 | Push the modified file back into iRODS
|
---|
137 | irsync a.sqlite3 i:a.sqlite3
|
---|
138 |
|
---|
139 | GIMI iRODS Use Case 3
|
---|
140 | Suppose there are many files under /home/shuang/data that need to be copied into iRODS, we can mount the local directory directly into iRODS
|
---|
141 | imkdir /geniRenci/home/shuang/mountpoint
|
---|
142 | imcoll m filesystem /home/shuang/data /geniRenci/home/shuang/mountpoint
|
---|
143 | Work on the local files
|
---|
144 | Sync with iRODS
|
---|
145 | Irsync r /home/shuang/data i:/geniRenci/home/shuang/mountpoint
|
---|
146 |
|
---|
147 | GIMI iRODS Use Case 4
|
---|
148 | Data processing e.g. filtering files under /geniRenci/home/shuang
|
---|
149 | Write a rule called filter.r which filters files and save them under /geniRenci/home/shuang/filtered
|
---|
150 | irule F filter.r *Path=/geniRenci/home/shuang
|
---|
151 |
|
---|
