◆ DisableImplicitMT()

void ROOT::DisableImplicitMT ( )

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

Definition at line 593 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] numthreads Number 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:

TDataFrame 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 baskets 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

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 576 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.

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

Definition at line 546 of file TROOT.cxx.

◆ Error()

void ROOT::Error	(	ErrorHandler_t	func,
		int	code,
		const char *	va_fmt,
			...
	)

Write error message and call a handler, if required.

Definition at line 565 of file DaemonUtils.cxx.

◆ ErrorInfo()

void ROOT::ErrorInfo	(	const char *	va_fmt,
			...
	)

Formats a string in a circular formatting buffer and prints the string.

Appends a newline. Cut & Paste from Printf in base/src/TString.cxx

static

Definition at line 49 of file RConversionRuleParser.cxx.

◆ FromHumanReadableSize() [1/2]

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

str	the string to be parsed
value	will 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.

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
