wrench::BatchComputeService

class 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
