| BareMetalComputeService (const std::string &hostname, const std::map< std::string, std::tuple< unsigned long, double >> compute_resources, std::string scratch_space_mount_point, WRENCH_PROPERTY_COLLECTION_TYPE property_list={}, WRENCH_MESSAGE_PAYLOADCOLLECTION_TYPE messagepayload_list={}) | |

| Constructor. More... | |
| virtual bool | supportsCompoundJobs () override |
| Returns true if the service supports compound jobs. More... | |
| virtual bool | supportsPilotJobs () override |
| Returns true if the service supports pilot jobs. More... | |
| virtual bool | supportsStandardJobs () override |
| Returns true if the service supports standard jobs. More... | |
| Public Member Functions inherited from wrench::ComputeService | |
| std::map< std::string, double > | getCoreFlopRate () |
| Get the per-core flop rate of the compute service's hosts. More... | |
| double | getFreeScratchSpaceSize () |
| Get the free space on the compute service's scratch storage space. More... | |
| std::vector< std::string > | getHosts () |
| Get the list of the compute service's compute host. More... | |
| std::map< std::string, double > | getMemoryCapacity () |
| Get the RAM capacities for each of the compute service's hosts. More... | |
| unsigned long | getNumHosts () |
| Get the number of hosts that the compute service manages. More... | |
| std::map< std::string, double > | getPerHostAvailableMemoryCapacity () |
| Get ram availability for each of the compute service's host. More... | |
| std::map< std::string, unsigned long > | getPerHostNumCores () |
| Get core counts for each of the compute service's host. More... | |
| std::map< std::string, unsigned long > | getPerHostNumIdleCores () |
| Get idle core counts for each of the compute service's host. More... | |
| std::shared_ptr< StorageService > | getScratchSharedPtr () |
| Get a shared pointer to the compute service's scratch storage space. More... | |
| unsigned long | getTotalNumCores () |
| Get the total core counts for all hosts of the compute service. More... | |
| virtual unsigned long | getTotalNumIdleCores () |
| Get the total idle core count for all hosts of the compute service. Note that this doesn't mean that asking for these cores right will mean immediate execution (since jobs may be pending and "ahead" in the queue, e.g., because they depend on current actions that are not using all available resources). More... | |
| double | getTotalScratchSpaceSize () |
| Get the total capacity of the compute service's scratch storage space. More... | |
| double | getTTL () |
| Get the time-to-live of the compute service. More... | |
| virtual bool | hasScratch () const |
| Checks if the compute service has a scratch space. More... | |
| virtual bool | isThereAtLeastOneHostWithIdleResources (unsigned long num_cores, double ram) |
| Method to find out if, right now, the compute service has at least one host with some idle number of cores and some available RAM. Note that this doesn't mean that asking for these resources right will mean immediate execution (since jobs may be pending and "ahead" in the queue, e.g., because they depend on current actions that are not using all available resources). More... | |
| void | stop () override |
| Stop the compute service. | |
| virtual void | stop (bool send_failure_notifications, ComputeService::TerminationCause termination_cause) |
| Stop the compute service. More... | |
| void | terminateJob (std::shared_ptr< CompoundJob > job) |
| Terminate a previously-submitted job (which may or may not be running yet) More... | |

| Throws an exception if the service is not up. More... | |
| std::string | getHostname () |
| Get the name of the host on which the service is / will be running. More... | |
| double | getNetworkTimeoutValue () |
| Returns the service's network timeout value. More... | |
