我需要通过 Perl API 向 SLURM 提交作业的这种“job_desc_msg_t”格式是什么？

Question

Perl API for SLURM表示提交带有API的作业需要我们给它一个"job description"（$job_desc或$job_desc_msg），这具有结构 job_desc_msg_t 但它没有说明 job_desc_msg_t 是什么。

更新：我在 slurm.h starting at line 1162 中找到了它，所以我猜我需要传入一个具有类似结构的散列。

根据手册页，这正是您必须执行的操作。

Typicaly, C structures are converted to (maybe blessed) Perl hash references, with field names as hash keys. Arrays in C are converted to arrays in Perl. For example, there is a structure "job_info_msg_t":
typedef struct job_info_msg {
    time_t last_update;     /* time of latest info */
    uint32_t record_count;  /* number of records */
    job_info_t *job_array;  /* the job records */
} job_info_msg_t;
This will be converted to a hash reference with the following structure:
{
    last_update => 1285847672,
    job_array => [ {account => 'test', alloc_node => 'ln0', alloc_sid => 1234, ...},
                   {account => 'debug', alloc_node => 'ln2', alloc_sid => 5678, ...},
                   ...
                 ]
}
Note the missing of the "record_count" field in the hash. It can be derived from the number of elements in array "job_array".

To pass parameters to the API functions, use the corresponding hash references, for example:
$rc = $slurm->update_node({node_names => 'node[0-7]', node_state => NODE_STATE_DRAIN});
Please see "<slurm/slurm.h>" for the definition of the structures.

What is this `job_desc_msg_t` format that I need to submit jobs to SLURM via the Perl API?
