20

|
// |
|
21
|
|
|
// In this system: |
|
22
|
|
|
// - each user (job submitter) has a 'sandbox' where they can store files |
|
23
|
|
|
// on the BOINC server, via a web interface. |
|
24
|
|
|
// These files are mutable; you can modify a file w/ a given name. |
|
25
|
|
|
// - files are stored in project/sandbox/<userid>/ |
|
26
|
|
|
// - When a file is uploaded, its size and MD5 are computed and stored |
|
27
|
|
|
// in an 'info file' in a parallel dir, project/sandbox/<userid>/.md5/ |
|
28
|
|
|
// |
|
29
|
|
|
// Sandbox files can be used for web-based job submissions systems |
|
30
|
|
|
// like BUDA and autodock on BOINC Central. |
|
31
|
|
|
// Typically they are used as job input files or app files, |
|
32
|
|
|
// in which case they are downloadable by BOINC clients. |
|
33
|
|
|
// When a file is used in this way, |
|
34
|
|
|
// it must be copied to the download hierarchy, |
|
35
|
|
|
// and assigned a physical name that includes its MD5. |
|
36
|
|
|
// The name can depend on the role of the file; |
|
37
|
|
|
// e.g. it can include a batch ID or BUDA app name |
