TProofPlayer Class Reference

Internal class steering processing in PROOF.

Instances of the TProofPlayer class are created on the worker nodes per session and do the processing. Instances of its subclass - TProofPlayerRemote are created per each query on the master(s) and on the client. On the master(s), TProofPlayerRemote coordinate processing, check the dataset, create the packetizer and take care of merging the results of the workers. The instance on the client collects information on the input (dataset and selector), it invokes the Begin() method and finalizes the query by calling Terminate().

Int_t TProofPlayer::SavePartialResults ( Bool_t  queryend = kFALSE,

virtual

Save the partial results of this query to a dedicated file under the user data directory.

The file name has the form <session_tag>.q<query_seq_num>.root The file pat and the file are created if not existing already. Only objects in the outputlist not being TProofOutputFile are saved. The packets list 'packets' is saved if given. Trees not attached to any file are attached to the open file. If 'queryend' is kTRUE evrything is written out (TTrees included). The actual saving action is controlled by 'force' and by fSavePartialResults / fSaveResultsPerPacket:

fSavePartialResults = kFALSE/kTRUE no-saving/saving fSaveResultsPerPacket = kFALSE/kTRUE save-per-query/save-per-packet

The function CheckMemUsage sets fSavePartialResults = 1 if fSaveMemThreshold > 0 and ProcInfo_t::fMemResident >= fSaveMemThreshold: from that point on partial results are always saved and expensive calls to TSystem::GetProcInfo saved. The switch fSaveResultsPerPacket is instead controlled by the user or admin who can also force saving in all cases; parameter PROOF_SavePartialResults or RC env ProofPlayer.SavePartialResults . However, if 'force' is kTRUE, fSavePartialResults and fSaveResultsPerPacket are ignored. Return -1 in case of problems, 0 otherwise.
