Unable to setup Co-scheduling multiple application in Mercury

[Ankit-1204]

Hello

I have was able to successfully run a single application using Mercury, the .py file was as follows

import sst
from sst.merlin.base import *
from sst.merlin.endpoint import *
from sst.merlin.interface import *
from sst.merlin.topology import *
from sst.hg import *

if __name__ == "__main__":

    PlatformDefinition.loadPlatformFile("platform_file_hg_test")
    PlatformDefinition.setCurrentPlatform("platform_hg_test")
    platform = PlatformDefinition.getCurrentPlatform()

    # ── Rank count ──────────────────────────────────────────────────
    num_ranks = 16

    platform.addParamSet("operating_system", {
        "verbose" : 1,

        # ── App identity ──────────────────────────────────────────
        "app1.name"             : "project",           # matches -Dssthg_app_name=project
        "app1.exe_library_name" : "project-hgcc",       # matches libproject-hgcc.so

        "app1.argv" : "....",

        "app1.verbose" : 1,
        "app1.dependencies" : ["sumi"],
        "app1.libraries"    : [
            "systemlibrary:SystemLibrary",
            "computelibrary:ComputeLibrary",
            "mask_mpi:MpiApi",
        ]
    })

    topo = topoHyperX()
    topo.shape = "8x8"
    topo.width = "1x1"
    topo.local_ports = 1
    ep = HgJob(0, num_ranks)

    system = System()
    system.setTopology(topo)
    system.allocateNodes(ep, "linear")
    system.build()

However when attempting to Co-Schedule 2 different projects using following .py file

import sst
from sst.merlin.base import *
from sst.merlin.endpoint import *
from sst.merlin.interface import *
from sst.merlin.topology import *
from sst.hg import *

if __name__ == "__main__":

    PlatformDefinition.loadPlatformFile("platform_file_hg_test")
    PlatformDefinition.setCurrentPlatform("platform_hg_test")
    platform = PlatformDefinition.getCurrentPlatform()

    npx, npy, npz = 4, 4, 2
    proj2_ranks = npx * npy * npz
    proj1_ranks = npx * npy * npz

    
    proj1_job= HgJob(1, proj1_ranks)
    proj1_job.os.addParams({
        "verbose": 1,
        "app1.name":             "project1",
        "app1.exe_library_name": "project1-hgcc",
        "app1.argv": (
            "....."   
            "....."
        ) % (npx, npy, npz),
        "app1.verbose":          1,
        "app1.dependencies":     ["sumi"],
        "app1.libraries": [
            "systemlibrary:SystemLibrary",
            "computelibrary:ComputeLibrary",
            "mask_mpi:MpiApi",
        ],
    })
    proj2_job= HgJob(0, proj2_ranks)
    proj2_job.os.addParams({
        "verbose": 1,
        "app1.name":             "project2",
        "app1.exe_library_name": "project2-hgcc",
        "app1.argv":             "....",
        "app1.verbose":          1,
        "app1.dependencies":     ["sumi"],
        "app1.libraries": [
            "systemlibrary:SystemLibrary",
            "computelibrary:ComputeLibrary",
            "mask_mpi:MpiApi",
        ],
    })
    topo = topoHyperX()
    topo.shape = "8x8"
    topo.width = "1x1"
    topo.local_ports = 1

    system = System()
    system.setTopology(topo)
    system.allocateNodes(proj1_job, "linear")
    system.allocateNodes(proj2_job, "linear")
    system.build()

It doesn't run properly as expected. I have no way of verifying if this is the correct method to Co-Schedule the Application since documentation for it is scarce.

Any help or guide regarding how to Co-Schedule the applications for Mercury would be really appreciated

Thank You
