5 | Computer(s) used for the whole Leginon system need to support five functions: |
||
6 | 4 | Amber Herold | # TEM/Camera control and data output (by python-side packages of Leginon |
7 | 1 | Amber Herold | system) |
8 | 5 | Amber Herold | *Note:* The computer attached to the microscope/camera is used for this function. Therefore, it is on a Windows computer. |
9 | 4 | Amber Herold | # General Leginon operation such as target selection and image processing (processing |
10 | 1 | Amber Herold | server of Leginon system) |
11 | 4 | Amber Herold | # Image data storage. |
12 | # Other meta-data storage through MySQL database (by database server of Leginon |
||
13 | 1 | Amber Herold | system) |
14 | 4 | Amber Herold | # Web server (using PHP-side of Leginon system). |
15 | 1 | Amber Herold | |
16 | 6 | Amber Herold | *Important:* The MRC module that is used to load mrc formatted files to the web pages is not compiled on Windows. Therefore, this function must be on a linux box unless you don't need to see the images. |

20 | |||
21 | |||
22 | The five functions can be distributed to five different computers on a network or all on |
||
23 | one single computer. However, since the latter minimal setup requires the use of the computer |
||
24 | attached to the microscope for all functions, it is not advisable. |
||
25 | |||
26 | |||
27 | Processing server of Leginion is a multi-platform software, meaning it can run on both |
||
28 | Microsoft Windows and Linux. It is also inherently designed to utilize distributed systems on |
||
29 | a network. MySQL used in the database server is also supported by multiple platforms. This is |
||
30 | not true for the Web server because the custom MRC module used in the web viewer only compiles |
||
31 | on linux machines. Therefore, one of the computer not part of the microscope must be a linux. |
||
32 | The following examples show several arrangements that take advantage of distributed system. |
||
33 | Other combinations are possible, but will basically be variations on one of the following |
||
34 | themes. |
||
35 | |||
36 | |||
37 | |||
38 | h2. A: 1 Windows computer (attached to the Microscope) & 1 Linux computer (for all |
||
39 | other functions, separate from the Microscope) (Good for single user and small-scale |
||
40 | acquisition) |
||
41 | |||
42 | |||
43 | |||
44 | |||
45 | |||
46 | * Install the latest processing server side of Leginon release (and supporting |
||
47 | packages) on the Windows computer controlling the microscope and on the Linux computer |
||
48 | which is to run Leginon image acquisition and processing. |
||
49 | |||
50 | |||
51 | * Install the additional modules needed for CCD camera and film interaction on the |
||
52 | Windows computer controlling the microscope. |
||
53 | |||
54 | |||
55 | * Install MySQL, PHP, the Apache Web Server, and dbem tools only on the Linux |
||
56 | computer that will perform these functions, (i.e. NOT the computer controlling the |
||
57 | microscope). |
||
58 | |||
59 | |||
60 | |||
61 | |||
62 | |||
63 | |||
64 | |||
65 | |||
66 | |||
67 | h2. B: 1 Windows computer (attached to the Microscope) & 4 Linux computers (one for |
||
68 | each function) (Good for multiple microsopes, users and large-scale acquisition) |
||
69 | |||
70 | |||
71 | |||
72 | This is the set-up at NRAMM. It has the processing server side of Leginon installed on |
||
73 | the Windows computer attached to the microscope and on the Linux computer that is used for |
||
74 | running Leginon. A second Linux machine is dedicated to the database while the web-based |
||
75 | viewer is hosted by another server. |
||
76 | |||
77 | |||
78 | |||
79 | |||
80 | * Install the python-side Leginon (and supporting packages) on the Windows computer |
||
81 | controlling the microscope and on the Linux computer that is to run Leginon. You can |
||
82 | make the latter installation accessable to any numbers of linux computers on your |
||
83 | network. |
||
84 | |||
85 | |||
86 | * Install MySQL, PHP, the Apache Web Server, and dbem tools on the second Linux |
||
87 | computer that will serve as the database/web server/PHP host. |
||
88 | |||
89 | |||
90 | * The computer hosting the data storage should be accessable by all linux |
||
91 | boxes. |
||
92 | |||
93 | |||
94 | |||
95 | |||
96 | |||
97 | |||
98 | |||
99 | |||
100 | |||
101 | h2. C: 1 Windows computer (attached to the Microscope), 1 Windows computer running python- |
||
102 | and MySQL-side functions and 1 Linux computer as web server (Has been applied |
||
103 | successfully) |
||
104 | |||
105 | |||
106 | |||
107 | The data storage may be on one of these computers that is accessable by other |
||
108 | computers. |
