| 4 | // OptInt |
| 5 | // |
| 6 | // Interface to set some of the optimized IO parameters. Use Compress or Decompress |
| 7 | // to compress or decompress data. |
| 8 | // |
| 9 | // The following zip modes are supported: |
| 10 | // Set ZipMode to be used in R__zip. Supported values range from 1 to 5, where |
| 11 | // 1 == gzip (http://www.gzip.org/, standard in ROOT) |
| 12 | // 2 == bzip2 (http://www.bzip.org/) |
| 13 | // 3 == lzo (http://www.oberhumer.com/opensource/lzo/) |
| 14 | // 4 == rle (http://bcl.comli.eu/) |
| 15 | // 5 == lzma (http://www.7-zip.org/sdk.html) |
| 16 | // 99 == combination of 1 to 5. |
| 17 | // |
| 18 | // Additionally you can specify the compression fraction that must be reached to accept result of |
| 19 | // the "heavy" compression algorithms. Negative values turn off usage of the specific compression |
| 20 | // algorithm in ZipMode=99. |
| 21 | // |
| 22 | // In order to make use of all of this, make sure you preload MitCommonOptIO.so. This can be |
| 23 | // achieved by setting LD_PRELOAD to $CMSSW_BASE/lib/$SCRAM_ARCH/libMitCommonOptIO.so. |
| 24 | // |
| 25 | // In additon, you can use .rootrc, for example like |
| 26 | // Root.ZipMode: 5 |
| 27 | // Root.OptIO.Verbose: 0 |
| 28 | // Root.OptIO.SMalloc: 0 |
| 29 | // Root.OptIO.LzoFraction: 1 |
| 30 | // Root.OptIO.GzipFraction: 1 |
| 31 | // Root.OptIO.BzipFraction: 1 |
| 32 | // Root.OptIO.LzmaFraction: 1 |
