wrench::BatchComputeService

class wrench::BatchComputeService : public wrench::ComputeService

A batch-scheduled compute service that manages a set of compute hosts and controls access to their resource via a batch queue.

In the current implementation of this service, like for many of its real-world counterparts, memory_manager_service partitioning among jobs onq the same host is not handled. When multiple jobs share hosts, which can happen when jobs require only a few cores per host and can thus be co-located on the same hosts in a non-exclusive fashion, each job simply runs as if it had access to the full RAM of each compute host it is scheduled on. The simulation of these memory_manager_service contended scenarios is thus, for now, not realistic as there is no simulation of the effects of memory_manager_service sharing (e.g., swapping).

Public Functions

BatchComputeService(const std::string &hostname, std::vector<std::string> compute_hosts, std::string scratch_space_mount_point, WRENCH_PROPERTY_COLLECTION_TYPE property_list = {}, WRENCH_MESSAGE_PAYLOADCOLLECTION_TYPE messagepayload_list = {})

Constructor.

Parameters

  • hostname – the hostname on which to start the service

  • compute_hosts – the list of names of the available compute hosts

    • the hosts must be homogeneous (speed, number of cores, and RAM size)

    • all cores are usable by the BatchComputeService service on each host

    • all RAM is usable by the BatchComputeService service on each host

  • scratch_space_mount_point – the mount point of the scratch storage space for the service (”” means “no scratch space”)

  • property_list – a property list that specifies BatchComputeServiceProperty values ({} means “use all defaults”)

  • messagepayload_list – a message payload list that specifies BatchComputeServiceMessagePayload values ({} means “use all defaults”)

bool supportsCompoundJobs() override

Returns true if the service supports compound jobs.

Returns

true or false

bool supportsPilotJobs() override

Returns true if the service supports pilot jobs.

Returns

true or false

bool supportsStandardJobs() override

Returns true if the service supports standard jobs.

Returns

true or false
