Detailed Description

Function Documentation

int drmaa_init (const char contact, char error_diagnosis, size_terror_diag_len)

The drmaa_init() function SHALL initialize DRMAA library and create a new DRMAA session, using the contact parameter, if provided, to determine to which DRMS to connect. This function MUST be called before any other DRMAA function, except for drmaa_get_DRM_system(), drmaa_get_DRMAA_implementation(), drmaa_get_contact(), and drmaa_strerror(). If contact is NULL, the default DRM system SHALL be used, provided there is only one DRMAA implementation in the provided binary module. When there is more than one DRMAA implementation in the binary module, drmaa_init() SHALL return the DRMAA_ERRNO_NO_DEFAULT_CONTACT_STRING_SELECTED error code. The drmaa_init() function SHOULD be called by only one of the threads. The main thread is RECOMMENDED. A call by another thread SHALL return the DRMAA_ERRNO_ALREADY_ACTIVE_SESSION error code.

int drmaa_exit (char *error_diagnosis, size_terror_diag_len)

The drmaa_exit() function SHALL disengage from DRMAA library and allow the DRMAA library to perform any necessary internal cleanup. This routine SHALL end the current DRMAA session but SHALL NOT affect any jobs (e.g, queued and running jobs SHALL remain queued and running). drmaa_exit() SHOULD be called by only one of the threads. The first call to call drmaa_exit() by a thread will operate normally. All other calls from the same and other threads SHALL fail, returning a DRMAA_ERRNO_NO_ACTIVE_SESSION error code.

int drmaa_set_vector_attribute (drmaa_job_template_t jt, const char name, const char value[], char error_diagnosis, size_terror_diag_len)

The function drmaa_set_vector_attribute() SHALL set the vector attribute, name, in the job template, jt, to the value(s), value. The DRMAA implementation MUST accept value values that are arrays of one or more strings terminated by a NULL entry.

int drmaa_get_attribute_names (drmaa_attr_names_t **values, char *error_diagnosis, size_terror_diag_len)

The function drmaa_get_attribute_names() SHALL return the set of supported scalar attribute names in an opaque names string vector stored in values. This vector SHALL include all required scalar attributes, all supported optional scalar attributes, all DRM-specific scalar attributes, and no unsupported optional attributes.

int drmaa_get_vector_attribute_names (drmaa_attr_names_t **values, char *error_diagnosis, size_terror_diag_len)

The function drmaa_get_vector_attribute_names() SHALL return the set of supported vector attribute names in an opaque names string vector stored in values. This vector SHALL include all required vector attributes, all supported optional vector attributes, all DRM-specific vector attributes, and no unsupported optional attributes.
