// The following zip modes are supported:
|
| 9 |
|
|
// Set ZipMode to be used in R__zip. Supported values range from 1 to 5, where
|
| 10 |
|
|
// 1 == gzip (http://www.gzip.org/, standard in ROOT)
|
| 11 |
|
|
// 2 == bzip2 (http://www.bzip.org/)
|
| 12 |
|
|
// 3 == lzo (http://www.oberhumer.com/opensource/lzo/)
|
| 13 |
|
|
// 4 == rle (http://bcl.comli.eu/)
|
| 14 |
|
|
// 5 == lzma (http://www.7-zip.org/sdk.html)
|
| 15 |
|
|
// 99 == combination of 1 to 5.

|
|
// Additionally you can specify the compression fraction that must be reached to accept result of
|
| 18 |
|
|
// the "heavy" compression algorithms. Negative values turn off usage of the specific compression
|
| 19 |
|
|
// algorithm in ZipMode=99.

|
// In order to make use of all of this, make sure you preload MitCommonOptIO.so. This can be
|
| 22 |
|
|
// achieved by setting LD_PRELOAD to $CMSSW_BASE/lib/$SCRAM_ARCH/libMitCommonOptIO.so.
|
| 23 |
|
|
//
|
| 24 |
|
|
// In additon, you can use .rootrc, for example like
|
| 25 |
|
|
// Root.ZipMode: 5
|
| 26 |
|
|
// Root.OptIO.Verbose: 0
|
| 27 |
|
|
// Root.OptIO.SMalloc: 0
|
| 28 |
|
|
// Root.OptIO.LzoFraction: 1
|
| 29 |
|
|
// Root.OptIO.GzipFraction: 1
|
| 30 |
|
|
// Root.OptIO.BzipFraction: 1
|
| 31 |

// Root.OptIO.LzmaFraction: 1
