NAME

drmaa_strerror, drmaa_get_contact, drmaa_version, drmaa_get_DRM_system - Miscellaneous DRMAA functions.

 

SYNOPSIS

#include drmaa.h

const char *drmaa_strerror(
int drmaa_errno
);

int drmaa_get_contact(
char *contact, size_t contact_len, char *error_diagnosis, size_t error_diag_len
);

int drmaa_version(
unsigned int *major, unsigned int *minor, char *error_diagnosis, size_t error_diag_len
);

int drmaa_get_DRM_system(
char *drm_system, size_t drm_system_len, char *error_diagnosis, size_t error_diag_len
);

int drmaa_get_DRMAA_implementation(
char *drm_impl, size_t drm_impl_len, char *error_diagnosis, size_t error_diag_len
);

 

DESCRIPTION

The drmaa_strerror() function returns a message text associated with the DRMAA error number, drmaa_errno. For invalid DRMAA error codes `NULL' is returned.  

drmaa_get_contact()

The drmaa_get_contact() returns an opaque string containing contact information related to the current DRMAA session to be used with the function. The opaque string contains the information required by drmaa_init() to reconnect to the current session instead of creating a new session. function.

The drmaa_get_contact() function returns the same value before and after is called.

 

drmaa_version()

The drmaa_version() function returns into the integers pointed to by major and minor, the major and minor version numbers of the DRMAA library. For a DRMAA 1.0 compliant implementation `1' and `0' will be returned in major and minor, respectively.

 

drmaa_get_DRM_system()

The drmaa_get_DRM_system() function returns into drm_system up to drm_system_len characters of a string containing Sun Grid Engine product and version information.

The drmaa_get_DRM_system() function returns the same value before and after is called.

 

drmaa_get_DRMAA_implementation()

The drmaa_get_DRMAA_implementation() function returns into drm_system up to drm_system_len characters of a string containing the Sun Grid Engine DRMAA implementation version information. In the current implementation, the drmaa_get_DRMAA_implementation() function returns the same result as the drmaa_get_DRM_system() function.

The drmaa_get_DRMAA_implementation() function returns the same value before and after is called.

 

ENVIRONMENTAL VARIABLES

SGE_ROOT
Specifies the location of the Sun Grid Engine standard configuration files.
SGE_CELL
If set, specifies the default Sun Grid Engine cell to be used. To address a Sun Grid Engine cell Sun Grid Engine uses (in the order of precedence):

The name of the cell specified in the environment variable SGE_CELL, if it is set.

The name of the default cell, i.e. default.

SGE_DEBUG_LEVEL
If set, specifies that debug information should be written to stderr. In addition the level of detail in which debug information is generated is defined.
SGE_QMASTER_PORT
If set, specifies the tcp port on which is expected to listen for communication requests. Most installations will use a services map entry instead to define that port.
 

RETURN VALUES

Upon successful completion, drmaa_get_contact(), drmaa_version(), and drmaa_get_DRM_system() return DRMAA_ERRNO_SUCCESS. Other values indicate an error. Up to error_diag_len characters of error related diagnosis information is then provided in the buffer error_diagnosis.

 

ERRORS

The drmaa_get_contact(), drmaa_version(), drmaa_get_DRM_system(), and drmaa_get_DRMAA_implementation() will fail if:  

DRMAA_ERRNO_INTERNAL_ERROR

Unexpected or internal DRMAA error, like system call failure, etc.  

DRMAA_ERRNO_DRM_COMMUNICATION_FAILURE

Could not contact DRM system for this request.  

DRMAA_ERRNO_AUTH_FAILURE

The specified request is not processed successfully due to authorization failure.  

DRMAA_ERRNO_INVALID_ARGUMENT

The input value for an argument is invalid.  

DRMAA_ERRNO_NO_MEMORY

Failed allocating memory.

The drmaa_get_contact() and drmaa_get_DRM_system() will fail if:  

DRMAA_ERRNO_NO_ACTIVE_SESSION

Failed because there is no active session.
