◆ DisableImplicitMT()

void ROOT::DisableImplicitMT ( )

Disables the implicit multi-threading in ROOT (see EnableImplicitMT).

Definition at line 597 of file TROOT.cxx.

◆ EnableImplicitMT()

void ROOT::EnableImplicitMT ( UInt_t  numthreads = 0)

Enable ROOT's implicit multi-threading for all objects and methods that provide an internal parallelisation mechanism.

Parameters
[in]numthreadsNumber of threads to use. If not specified or set to zero, the number of threads is automatically decided by the implementation. Any other value is used as a hint.

ROOT must be built with the compilation flag imt=ON for this feature to be available. The following objects and methods automatically take advantage of multi-threading if a call to EnableImplicitMT has been made before usage:

  • RDataFrame internally runs the event-loop by parallelizing over clusters of entries
  • TTree::GetEntry reads multiple branches in parallel
  • TTree::FlushBaskets writes multiple baskets to disk in parallel
  • TTreeCacheUnzip decompresses the baskets contained in a TTreeCache in parallel
  • THx::Fit performs in parallel the evaluation of the objective function over the data
  • TMVA::DNN trains the deep neural networks in parallel
  • TMVA::BDT trains the classifier in parallel and multiclass BDTs are evaluated in parallel

EnableImplicitMT calls in turn EnableThreadSafety. The 'numthreads' parameter allows to control the number of threads to be used by the implicit multi-threading. However, this parameter is just a hint for ROOT: it will try to satisfy the request if the execution scenario allows it. For example, if ROOT is configured to use an external scheduler, setting a value for 'numthreads' might not have any effect.

Definition at line 580 of file TROOT.cxx.

◆ EnableThreadSafety()

void ROOT::EnableThreadSafety ( )

Enables the global mutex to make ROOT thread safe/aware.

The following becomes safe:

  • concurrent construction and destruction of TObjects, including the ones registered in ROOT's global lists (e.g. gROOT->GetListOfCleanups(), gROOT->GetListOfFiles())
  • concurrent usage of different ROOT objects from different threads, including ones with global state (e.g. TFile, TTree, TChain) with the exception of graphics classes (e.g. TCanvas)
  • concurrent calls to ROOT's type system classes, e.g. TClass and TEnum
  • concurrent calls to the interpreter through gInterpreter
  • concurrent loading of ROOT plug-ins

In addition, gDirectory, gFile and gPad become a thread-local variable. In all threads, gDirectory defaults to gROOT, a singleton which supports thread-safe insertion and deletion of contents. gFile and gPad default to nullptr, as it is for single-thread programs.

The ROOT graphics subsystem is not made thread-safe by this method. In particular drawing or printing different canvases from different threads (and analogous operations such as invoking Draw on a TObject) is not thread-safe.

Note that there is no DisableThreadSafety(). ROOT's thread-safety features cannot be disabled once activated.

Definition at line 549 of file TROOT.cxx.

◆ FindEndSymbol()

static

Definition at line 62 of file RConversionRuleParser.cxx.

◆ FromHumanReadableSize() [1/2]

template<typename T >
EFromHumanReadableSize ROOT::FromHumanReadableSize ( ROOT::Internal::TStringView  str,
T &  value 
)

Definition at line 158 of file StringConv.hxx.

◆ FromHumanReadableSize() [2/2]

template<typename T >
EFromHumanReadableSize ROOT::FromHumanReadableSize ( std::string_view  str,
T &  value 
)

Convert strings like the following into byte counts 5MB, 5 MB, 5M, 3.7GB, 123b, 456kB, 3.7GiB, 5MiB with some amount of forgiveness baked into the parsing.

For this routine we use the official SI unit where the [i] is reserved for the 'legacy' power of two units. 1KB = 1000 bytes, 1KiB = 1024 bytes.

Parameters
strthe string to be parsed
valuewill be updated with the result if and only if the parse is successful and does not overflow for the type of value.
Returns
return a EFromHumanReadableSize enum value indicating the success or failure of the parse.

◆ RemoveClass()

void ROOT::RemoveClass ( const char *  cname)

Global function called by the dtor of a class's init class (see the ClassImp macro).

Definition at line 837 of file TClassTable.cxx.

◆ ResetClassVersion()

void ROOT::ResetClassVersion ( TClass cl,
const char *  cname,
Short_t  newid 
)

Global function to update the version number.

This is called via the RootClassVersion macro.

if cl!=0 and cname==-1, set the new class version if and only is greater than the existing one and greater or equal to 2; and also ignore the request if fVersionUsed is true.

Note on class version number:

  • If no class has been specified, TClass::GetVersion will return -1
  • The Class Version 0 request the whole object to be transient
  • The Class Version 1, unless specify via ClassDef indicates that the I/O should use the TClass checksum to distinguish the layout of the class
