Please note: DRMAA for Slurm is a continuation of PSNC DRMAA for SLURM by an unrelated developer.
DRMAA for Slurm Workload Manager (Slurm) is an implementation of Open Grid Forum Distributed Resource Management Application API (DRMAA) version 1 for submission and control of jobs to Slurm. Using DRMAA, grid applications builders, portal developers and ISVs can use the same high-level API to link their software with different cluster/resource management systems.
DRMAA for Slurm was originally developed at the Poznań Supercomputing and Networking Center as PSNC DRMAA for SLURM. Following the unexpected death in 2013 of its primary maintainer, Mariusz Mamoński, there has been little additional development from PSNC, and no new releases.
This fork is maintained by Nate Coraor and was originally created in 2014 to add support for Slurm's --clusters (-M) option. Since that time, others have found it useful and additional features and bug fixes have been added. However, the majority of the credit for this work belongs to the original authors (found below). In 2017, current maintainer Piotr Kopta created psnc-apps/slurm-drmaa in Github, a snapshot of the unreleased 1.2.0 version (upon which this fork is also based) that has seen occasional work.
The title of the software in this fork has been changed from PSNC DRMAA for SLURM to simply DRMAA for Slurm. This change was made in order to alleviate confusion and differentiate from the canonical version. Additionally, this fork is not affiliated with PSNC; as such, releasing this software under PSNC's name would not be appropriate. However, this fork's maintainer is incredibly grateful for the work of the original authors of this software and the name change is in no way intended to minimize the efforts of those people.
DRMAA for Slurm is distributed as a source package which can be downloaded via the Releases section.
To compile and install the library, go to main source directory and type:
$ ./configure [options] && make
$ sudo make installThe library uses the standard GNU Autotools system, so standard configure arguments are available; see ./configure --help for a full list. The library was tested with Slurm versions 16.05 and 18.08. If you encountered any problems using the library on different systems, please see the contact section.
Notable ./configure script options:
--with-slurm-incSLURM_INCLUDE_PATHPath to Slurm header files (i.e. directory containing
slurm/slurm.h). By default the library tries to guess theSLURM_INCLUDE_PATHandSLURM_LIBRARY_PATHbased on location of thesrunexecutable.
--with-slurm-libSLURM_LIBRARY_PATHPath to Slurm libraries (i.e. directory containing
libslurm.a).
--prefixINSTALLATION_DIRECTORYRoot directory where PSNC DRMAA for Slurm shall be installed. When not given library is installed in
/usr/local.
--enable-debugCompiles library with debugging enabled (with debugging symbols not stripped, without optimizations, and with many log messages enabled). Useful when you are to debug DRMAA enabled application or investigate problems with DRMAA library itself.
There are no unusual requirements for basic usage of library: a C99 compiler and standard make program should suffice. If you have taken sources directly from this repository or wish to run test-suite you would need additional developer tools.
During DRMAA session initialization (drmaa_init), the library tries to read its configuration parameters from locations: /etc/slurm_drmaa.conf, ~/.slurm_drmaa.conf and from the file given in the $SLURM_DRMAA_CONF environment variable (if set to a non-empty string). If multiple configuration sources are present then all configurations are merged with values from user-defined files taking precedence (in the following order: $SLURM_DRMAA_CONF, ~/.slurm_drmaa.conf, /etc/slurm_drmaa.conf).
Currently recognized configuration parameters are:
cache_job_stateAccording to the DRMAA specification, every
drmaa_job_ps()call should query the DRM system for job state. With this option one may optimize communication with the DRM. If set to a positive integer,drmaa_job_ps()returns the remembered job state without communicating with the DRM forcache_job_stateseconds since the last update. By default the library conforms to the specification (no caching will be performed).Type: integer, default: 0
job_categoriesDictionary of job categories. Its keys are job categories names mapped to native specification strings. Attributes set by job category can be overridden by corresponding DRMAA attributes or native specification. The special category name
defaultis used when thedrmaa_job_categoryjob attribute is not set.Type: dictionary with string values, default: empty dictionary
The configuration file is in a form of a dictionary. A dictionary is set of zero or more key-value pairs. A key is a string, while a value can be a string, an integer or another dictionary.
configuration: dictionary | dictionary_body
dictionary: '{' dictionary_body '}'
dictionary_body: (string ':' value ',')*
value: integer | string | dictionary
string: unquoted-string | single-quoted-string | double-quoted-string
unquoted-string: [^ \t\n\r:,0-9][^ \t\n\r:,]*
single-quoted-string: '[^']*'
double-quoted-string: "[^"]*"
integer: [0-9]+The DRMAA interface allows passing DRM-dependent job submission options. Those options may be specified directly by setting the drmaa_native_specification job template attribute or indirectly by the drmaa_job_category job template attribute. The legal format of the native options looks like:
-A My_job_name -s -N 1-10List of parameters that can be passed in the drmaa_native_specification attribute:
| Native specification | Description |
|---|---|
| -A, --account=name | Charge job to specified accounts |
| --acctg-freq=list | Define the job accounting sampling interval |
| --comment=string | An arbitrary comment |
| -C, --constraint=list | Specify a list of constraints |
| -c, --cpus-per-task=n | Number of processors per task |
| --contiguous | If set, then the allocated nodes must form a contiguous set |
| -d, --dependency=list | Defer the start of this job until the specified dependencies have been satisfied completed |
| --exclusive | Allocate nodenumber of tasks to invoke on each nodes in exclusive mode when cpu consumable resource is enabled |
| --gres=list | Specifies a comma delimited list of generic consumable resources |
| -k, --no-kill | Do not automatically terminate a job of one of the nodes it has been allocated fails |
| -L, --licenses=license | Specification of licenses |
| -M, --clusters=list | Comma delimited list of clusters to issue commands to |
| --mail-type=type | Notify user by email when certain event types occur. Valid type values are BEGIN, END, FAIL, REQUEUE, and ALL (any state change) |
| --mem=MB | Minimum amount of real memory |
| --mem-per-cpu=MB | Maximum amount of real memory per allocated cpu required by a job |
| --mincpus=n | Minimum number of logical processors (threads) per node |
| -N, --nodes=minnodes[-maxnodes] | Number of nodes on which to run |
| -n, --ntasks=n | Number of tasks |
| --no-requeue | Specifies that the batch job should not be requeued after node failure |
| --ntasks-per-node=n | Number of tasks to invoke on each node |
| -p, --partition=partition | Partition requested |
| --qos=qos | Quality of Serice |
| --requeue | If set, permit the job to be requeued |
| --reservation=name | Allocate resources from named reservation |
| -s, --share | Job allocation can share nodes with other running jobs |
| --tmp=size[units] | Specify a minimum amount of temporary disk space |
| -w, --nodelist=hosts | Request a specific list of hosts |
| -x, --exclude=nodelist | Explicitly exclude certain nodes from the resources granted to the job |
Additionally, the following parameters to drmaa_native_specification are supported, but their use is discouraged in
favor of the corresponding DRMAA job attributes:
| Native specification | DRMAA job attribute | Description |
|---|---|---|
| -e, --error=pattern | drmaa_output_path | Connect the batch script's standard error directly to the file name specified in the pattern |
| -J, --job-name=name | drmaa_job_name | Specify a name for the job allocation |
| -o, --output=pattern | drmaa_error_path | Connect the batch script's standard output directly to the file name specified in the pattern |
| -t, --time=hours:minutes | drmaa_wct_hlimit | Set a maximum job wallclock time |
Descriptions of each parameter can be found in man sbatch.
