A key-value model for HPC resources in CEMC/CMA. Including models for:

• Slurm

Installation

Getting Started

The following example uses hpc-model-go to extract job id and job owner from a squeue -o %all query.

Create category list:

categoryList := slurm.QueryCategoryList{
    QueryCategoryList: hpcmodel.QueryCategoryList{
        CategoryList: []*hpcmodel.QueryCategory{
            {
                ID:                      "sinfo.partition",
                DisplayName:             "Partition",
                Label:                   "PARTITION",
                PropertyClass:           "StringProperty",
                PropertyCreateArguments: []string{},
                RecordParserClass:       "TokenRecordParser",
            },
            {
                ID:                      "sinfo.avail",
                DisplayName:             "Avail",
                Label:                   "AVAIL",
                PropertyClass:           "StringProperty",
                PropertyCreateArguments: []string{},
                RecordParserClass:       "TokenRecordParser",
            },
            {
                ID:                      "sinfo.nodes",
                DisplayName:             "Nodes(A/I/O/T)",
                Label:                   "NODES(A/I/O/T)",
                PropertyClass:           "StringProperty",
                PropertyCreateArguments: []string{},
                RecordParserClass:       "TokenRecordParser",
            },
            {
                ID:                      "sinfo.cpus",
                DisplayName:             "CPUs(A/I/O/T)",
                Label:                   "CPUS(A/I/O/T)",
                PropertyClass:           "StringProperty",
                PropertyCreateArguments: []string{},
                RecordParserClass:       "TokenRecordParser",
            },
        },
    },
}

Get squeue -o %all output.

cmd := exec.Command("sinfo", params...)
//fmt.Println(cmd.Args)
var out bytes.Buffer
cmd.Stdout = &out
err := cmd.Run()
if err != nil {
    return nil, fmt.Errorf("command ran error: %v", err)
}
s := out.String()
lines := strings.Split(s, "\n")

Build model from category list.

model, err := slurm.BuildModel(lines, categoryList, " ")

model contains data of all categories.

Test

Use go test to run all tests.
