RSL(5)

NAME
rsl - GRAM5 RSL Attributes

DESCRIPTION

arguments
    The command line arguments for the executable. Use quotes, if a space is required in a single argument.

count
    The number of executions of the executable. [Default: <literal>1</literal>]

directory
    Specifies the path of the directory the jobmanager will use as the default directory for the requested job. [Default: <literal>$(HOME)</literal>]

dry_run
    If dryrun = yes then the jobmanager will not submit the job for execution and will return success. [Default: <literal>no</literal>]

environment
    The environment variables that will be defined for the executable in addition to default set that is given to the job by the jobmanager.

executable
    The name of the executable file to run on the remote machine. If the value is a GASS URL, the file is transferred to the remote gass cache before executing the job and removed after the job has terminated.

expiration
    Time (in seconds) after a a job fails to receive a two-phase commit end signal before it is cleaned up. [Default: <literal>14400</literal>]

file_clean_up
    Specifies a list of files which will be removed after the job is completed.

file_stage_in
    Specifies a list of ("remote URL" "local file") pairs which indicate files to be staged to the nodes which will run the job.

file_stage_in_shared
    Specifies a list of ("remote URL" "local file") pairs which indicate files to be staged into the cache. A symlink from the cache to the "local file" path will be made.

file_stage_out
    Specifies a list of ("local file" "remote URL") pairs which indicate files to be staged from the job to a GASS-compatible file server.

gass_cache
    Specifies location to override the GASS cache location.

gram_my_job
    Obsolete and ignored. [Default: <literal>collective</literal>]

host_count
    Only applies to clusters of SMP computers, such as newer IBM SP systems. Defines the number of nodes ("pizza boxes") to distribute the "count" processes across.

job_type
    This specifies how the jobmanager should start the job. Possible values are single (even if the count > 1, only start 1 process or thread), multiple (start count processes or threads), mpi (use the appropriate method (e.g. mpirun) to start a program compiled with a vendor-provided MPI library. Program is started with count nodes), and condor (starts condor jobs in the "condor" universe.) [Default: <literal>multiple</literal>]

library_path
    Specifies a list of paths to be appended to the system-specific library path environment variables. [Default: <literal>$(GLOBUS_LOCATION)/lib</literal>]

loglevel
    Override the default log level for this job. The value of this attribute consists of a combination of the strings FATAL, ERROR, WARN, INFO, DEBUG, TRACE joined by the | character

logpattern
    Override the default log path pattern for this job. The value of this attribute is a string (potentially containing RSL substitutions) that is evaluated to the path to write the log to. If the resulting string contains the string $(DATE) (or any other RSL substitution), it will be reevaluated at log time.

max_cpu_time
    Explicitly set the maximum cputime for a single execution of the executable. The units is in minutes. The value will go through an atoi() conversion in order to get an integer. If the GRAM scheduler cannot set cputime, then an error will be returned.

max_memory
    Explicitly set the maximum amount of memory for a single execution of the executable. The units is in Megabytes. The value will go through an atoi() conversion in order to get an integer. If the GRAM scheduler cannot set maxMemory, then an error will be returned.

max_time
    The maximum walltime or cputime for a single execution of the executable. Walltime or cputime is selected by the GRAM scheduler being interfaced. The units is in minutes. The value will go through an atoi() conversion in order to get an integer.

max_wall_time
    Explicitly set the maximum walltime for a single execution of the executable. The units is in minutes. The value will go through an atoi() conversion in order to get an integer. If the GRAM scheduler cannot set walltime, then an error will be returned.

min_memory
    Explicitly set the minimum amount of memory for a single execution of the executable. The units is in Megabytes. The value will go through an atoi() conversion in order to get an integer. If the GRAM scheduler cannot set minMemory, then an error will be returned.

project
    Target the job to be allocated to a project account as defined by the scheduler at the defined (remote) resource.

proxy_timeout
    Obsolete and ignored. Now a job-manager-wide setting.

queue
    Target the job to a queue (class) name as defined by the scheduler at the defined (remote) resource.

remote_io_url
    Writes the given value (a URL base string) to a file, and adds the path to that file to the environment through the GLOBUS_REMOTE_IO_URL environment variable. If this is specified as part of a job restart RSL, the job manager will update the file’s contents. This is intended for jobs that want to access files via GASS, but the URL of the GASS server has changed due to a GASS server restart.

restart
    Start a new job manager, but instead of submitting a new job, start managing an existing job. The job manager will search for the job state file created by the original job manager. If it finds the file and successfully reads it, it will become the new manager of the job, sending callbacks on status and streaming stdout/err if appropriate. It will fail if it detects that the old jobmanager is still alive (via a timestamp in the state file). If stdout or stderr was being streamed over the network, new stdout and stderr attributes can be specified in the restart RSL and the jobmanager will stream to the new locations (useful when output is going to a GASS server started by the client that’s listening on a dynamic port, and the client was restarted). The new job manager will return a new contact string that should be used to communicate with it. If a jobmanager is restarted multiple times, any of the previous contact strings can be given for the restart attribute.

rsl_substitution
    Specifies a list of values which can be substituted into other rsl attributes' values through the $(SUBSTITUTION) mechanism.

save_state
    Causes the jobmanager to save it’s job state information to a persistent file on disk. If the job manager exits or is suspended, the client can later start up a new job manager which can continue monitoring the job.

savejobdescription
    Save a copy of the job description to $HOME [Default: <literal>no</literal>]

scratch_dir
    Specifies the location to create a scratch subdirectory in. A SCRATCH_DIRECTORY RSL substitution will be filled with the name of the directory which is created.

stderr
    The name of the remote file to store the standard error from the job. If the value is a GASS URL, the standard error from the job is transferred dynamically during the execution of the job. There are two accepted forms of this value. It can consist of a single destination: stderr = URL, or a sequence of destinations: stderr = (DESTINATION) (DESTINATION). In the latter case, the DESTINATION may itself be a URL or a sequence of an x-gass-cache URL followed by a cache tag. [Default: <literal>/dev/null</literal>]

stderr_position
    Specifies where in the file remote standard error streaming should be restarted from. Must be 0.

stdin
    The name of the file to be used as standard input for the executable on the remote machine. If the value is a GASS URL, the file is transferred to the remote gass cache before executing the job and removed after the job has terminated. [Default: <literal>/dev/null</literal>]

stdout
    The name of the remote file to store the standard output from the job. If the value is a GASS URL, the standard output from the job is transferred dynamically during the execution of the job. There are two accepted forms of this value. It can consist of a single destination: stdout = URL, or a sequence of destinations: stdout = (DESTINATION) (DESTINATION). In the latter case, the DESTINATION may itself be a URL or a sequence of an x-gass-cache URL followed by a cache tag. [Default: <literal>/dev/null</literal>]

stdout_position
    Specifies where in the file remote output streaming should be restarted from. Must be 0.

two_phase
    Use a two-phase commit for job submission and completion. The job manager will respond to the initial job request with a WAITING_FOR_COMMIT error. It will then wait for a signal from the client before doing the actual job submission. The integer supplied is the number of seconds the job manager should wait before timing out. If the job manager times out before receiving the commit signal, or if a client issues a cancel signal, the job manager will clean up the job’s files and exit, sending a callback with the job status as GLOBUS_GRAM_PROTOCOL_JOB_STATE_FAILED. After the job manager sends a DONE or FAILED callback, it will wait for a commit signal from the client. If it receives one, it cleans up and exits as usual. If it times out and save_state was enabled, it will leave all of the job’s files in place and exit (assuming the client is down and will attempt a job restart later). The timeoutvalue can be extended via a signal. When one of the following errors occurs, the job manager does not delete the job state file when it exits: GLOBUS_GRAM_PROTOCOL_ERROR_COMMIT_TIMED_OUT, GLOBUS_GRAM_PROTOCOL_ERROR_TTL_EXPIRED, GLOBUS_GRAM_PROTOCOL_ERROR_JM_STOPPED, GLOBUS_GRAM_PROTOCOL_ERROR_USER_PROXY_EXPIRED. In these cases, it can not be restarted, so the job manager will not wait for the commit signal after sending the FAILED callback

username
    Verify that the job is running as this user.
