    27 Introduction 
    28 ============ 
    29  
    30 PSNC DRMAA for LoadLeveler is an implementation of `Open Grid Forum`_ DRMAA_ 
    31 1.0 (Distributed Resource Management Application API) specification_ 
    32 for submission and control of jobs to `IBM Tivoli LoadLeveler`_.  Using DRMAA, 
    33 grid applications builders, portal developers and ISVs can use the same 
    34 high-level API to link their software with different cluster/resource 
    35 management systems. 
    36  
    37 This software also enables the integration of `SMOA Computing`_ with the 
    38 underlying LoadLeveler system for remote multi-user job submission and control 
    39 over Web Services. 
    40  
    41  
    42 Installation 
    43 ============ 
    44  
    45 To compile and install the library just go to main source directory 
    46 and type:: 
    47  
    48   $ ./configure [options] && make 
    49   $ sudo make install 
    50  
    51 The library was tested with LoadLeveler version 3.5. (for AIX operating systems). 
    52 If you encountered any problems using the library on the different systems, please use  
    53 the contact e-mails for reporting the problem. 
    54  
    55 Notable `./configure` script options: 
    56  
    57   `--with-ll-inc` LL_INCLUDE_PATH 
    58     Path to LL header files (i.e. directory containing `llapi.h` ). By default the library tries  
    59     to guess the `LL_INCLUDE_PATH` and `LL_LIBRARY_PATH` based on location 
    60     of the `llsubmit` executable. 
    61  
    62   `--with-ll-lib` LL_LIBRARY_PATH 
    63     Path to LL libraries (i.e. directory containing `libllapi.a` ). 
    64  
    65   `--prefix` INSTALLATION_DIRECTORY 
    66     Root directory where PSNC DRMAA for LoadLeveler shall be installed. 
    67     When not given library is installed alongside with LL. 
    68  
    69   `--enable-debug` 
    70     Compiles library with debugging enabled (with debugging symbols not 
    71     stripped, without optimizations, and with many log messages enabled). 
    72     Useful when you are to debug DRMAA enabled application 
    73     or investigate problems with DRMAA library itself. 
    74  
    75 There are no unusual requirements for basic usage of library: ANSI C 
    76 compiler and standard make program should suffice.  If you have taken 
    77 sources directly from SVN repository or wish to run test-suite you would 
    78 need additional `developer tools`_.  For further information regarding 
    79 GNU build system see the INSTALL file. 
    80  
    81  
    82 Configuration 
    83 ============= 
    84  
    85 During DRMAA session initialization (`drmaa_init`) library tries to 
    86 read its configuration parameters from locations: `/etc/ll_drmaa.conf`, 
    87 `~/.ll_drmaa.conf` and from file given in `LL_DRMAA_CONF` environment 
    88 variable (if set to non-empty string).  If multiple configuration 
    89 sources are present then all configurations are merged with values 
    90 from user-defined files taking precedence (in following order: 
    91 `$LL_DRMAA_CONF`, `~/.ll_drmaa.conf`, `/etc/ll_drmaa.conf`). 
    92  
    93 Currently recognized configuration parameters are: 
    94  
    95   cache_job_state 
    96     According to DRMAA specification every `drmaa_job_ps()` call should 
    97     query DRM system for job state.  With this option one may optimize 
    98     communication with DRM.  If set to positive integer `drmaa_job_ps()` 
    99     returns remembered job state without communicating with DRM for 
    100     `cache_job_state` seconds since last update.  By default library 
    101     conforms to specification (no caching will be performed). 
    102  
    103     Type: integer, default: 0 
    104  
    105   job_categories 
    106     Dictionary of job categories.  It's keys are job categories names 
    107     mapped to `native specification`_ strings.  Attributes set by job 
    108     category can be overridden by corresponding DRMAA attributes or 
    109     native specification.  Special category name `default` is used when 
    110     `drmaa_job_category` job attribute was not set. 
    111  
    112     Type: dictionary with string values, default: empty dictionary 
    113          
    114   terminate_job_on_vacated 
    115         Attribute which determines if job should be terminated just after entering the `vacated` state. 
    116          
    117         Type: integer, default: 1 
    118  
    119 Configuration file syntax 
    120 ------------------------- 
    121  
    122 Configuration file is in form a dictionary. 
    123 Dictionary is set of zero or more key-value pairs. 
    124 Key is a string while value could be a string, an integer 
    125 or another dictionary. 
    126 :: 
    127  
    128   configuration: dictionary | dictionary_body 
    129   dictionary: '{' dictionary_body '}' 
    130   dictionary_body: (string ':' value ',')* 
    131   value: integer | string | dictionary 
    132   string: unquoted-string | single-quoted-string | double-quoted-string 
    133   unquoted-string: [^ \t\n\r:,0-9][^ \t\n\r:,]* 
    134   single-quoted-string: '[^']*' 
    135   double-quoted-string: "[^"]*" 
    136   integer: [0-9]+ 
    137  
    138  
    139 Native specification 
    140 ==================== 
    141  
    142 DRMAA interface allows to pass DRM dependent job submission options. 
    143 Those options may be specified directly by setting `drmaa_native_specification` job 
    144 template attribute or indirectly by the `drmaa_job_category` job template attribute.  
    145 The legal format of the native options looks like:: 
    146  
    147   @ll_cmd_keyword1 = value @ll_cmd_keyword2 = value1 value2 value3  
    148  
    149 where the `ll_cmd_keyword` can be any of the `keyword`_ accepted by the LoadLeveler. It is user 
    150 responsibility to provide legal combination of the `drmaa_native_specification`/`drmaa_job_category` 
    151 and the other DRMAA attributes. 
    152  
    153 Release notes 
    154 ============= 
    155  * 1.0.1 - first public release 
    156  
    157 Known bugs and limitations 
    158 -------------------------- 
    159  
    160 Library covers all `DRMAA 1.0 specification`_ with exceptions listed 
    161 below.  It was successfully tested with `IBM Tivoli LoadLeveler`_ 3.5.0.5 on AIX 
    162 OS and passes 43/44 tests of the `official DRMAA test-suite`_. All mandatory and 
    163 nearly all optional job attributes (except job run duration soft limit, job run duration hard limit,  
    164 drmaa_transfer_files and drmaa_deadline_time) are implemented. 
    165  
    166 Known limitations: 
    167  
    168  * `drmaa_control()` - `DRMAA_CONTROL_RESUME` and `DRMAA_CONTROL_SUSPEND` are not implemented as suspending jobs in LoadLeveler requires administrator privileges.  
    169  
    170 .. note:: There are plans, depending on the end users feedback, to implement the RESUME/SUSPEND functionality by leveraging the checkpointing mechanism. 
    171
