  2. LSF Update • [Up to us to install it ourselves..] • Location of RPM’s and documentation for LSF: /afs/cern.ch/project/lsf/6.1/install http://batch.web.cern.ch/batch/doc-privinst.html https://uimon.cern.ch/twiki/bin/view/FIOgroup/LSFBatchHome • The latest version for SLC3 on i386 is LSF-2.4-GLIBC-2.3-6.1-22.i386.rpm (LSF core software) • LSF installation on Proof cluster (progress) https://uimon.cern.ch/twiki/bin/view/FIOgroup/LsfProof (we should continue updating this page) P. Nilsson

  3. Resources Interface • Main interface class • Additional info (config file, LSF requests, ..) is communicated via the constructors of the derived classes class TProofResources : public TObject { public: virtual TProofNodeInfo *GetMaster(void) = 0; virtual TList *GetWorkers(void) = 0; private: virtual TProofNodeInfo *GetNodeInfo(TString name) = 0; ClassDef(TProofResources,0) }; P. Nilsson

  4. Resources Interface • Static resources class • Reads and interprets the static config file • Creates a TList of TProofNodeInfo objects for workers and a single TProofNodeInfo object for the master • Implemented in TProof::StartSlaves (v5-06-01) class TProofResourcesStatic : public TProofResources { public: TProofResourcesStatic(const TString confDir, const TString fileName); // ctor virtual ~TProofResourcesStatic(void); // dtor TProofNodeInfo *GetMaster(void); // Return the master TList *GetWorkers(void); // Get all workers ...several private methods } P. Nilsson

  5. Resources Interface • LSF resources class • Submits a request to LSF system • Creates a TList of TProofNodeInfo objects for workers and a single TProofNodeInfo object for the master • Not implemented in Proof yet (stand-alone code is running on lxplus) class TProofResourcesLSF : public TProofResources { public: TProofResourcesLSF(Char_t *request, Int_t N); // ctor virtual ~TProofResourcesLSF(void); // dtor TProofNodeInfo *GetMaster(void); // Get the master (current host) TList *GetWorkers(void); // Get the workers ...several private methods } P. Nilsson

  6. Resources Interface • TNodeInfo data members • ‘Getters’ added for all data members enum ENodeType { kMaster, kSubMaster, kWorker }; ENodeType fNodeType; // Distinction between master, submaster and worker TString fNodeName; // Name of the node TString fWorkDir; // Working directory TString fOrdinal; // Worker ordinal number TString fImage; // File system image TString fId; // Id number TString fConfig; // Configuration file name [for submasters] TString fMsd; // ... [for submasters] Int_t fPort; // Port number Int_t fPerfIndex; // Performance index P. Nilsson

  7. Resources Interface • Done: TProof::StartSlaves() • Currently updating: TProofSuperMaster::StartSlaves() • Static config file used also used in TProofServ and TProofCondor P. Nilsson
