◆ DisableImplicitMT()

void ROOT::DisableImplicitMT ( )

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

Definition at line 570 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

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 555 of file TROOT.cxx.

◆ EnableThreadSafety()

void ROOT::EnableThreadSafety ( )

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

Definition at line 528 of file TROOT.cxx.

◆ FromHumanReadableSize() [1/2]

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.

◆ ResetClassVersion()

void ROOT::ResetClassVersion	(	TClass *	cl,

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
