getEventMap(), memory consumption [message #1389] Mon, 11 February 2008 02:08 Go to previous message

Dear lcio users!

I use Marlin and lcio in the versions comming along ilcsoft v01-03.
I noticed that the new direct access feature of lcio, where the message

SIOReader::getEventMap() recreating event map for direct access ...

comes from(?),

leads to a huge memory consumption. I run over raw data of the calice hcal testbeam. These have a volume of 2GB. It takes about a minute until

SIOReader::getEventMap() : done

and 1GB of memory.

Is there a way to turn the direct access feature off or do I have a problem somewhere else? Beside the ProgressHandler I turned all processors off.
