Description

It seems that artdaq demo will not run on a system with less than about 5 or 6 GB of
RAM and 2 GB of swap.

We should think about adding a check for the amount of memory a system has.
On my system, which had 4 GB RAM and 2 GB swap, the OOM (Out Of Memory) monitoring
ended up killing my firefox processes and then g++ also.

This is still an issue, and should probably be implemented in quick-mrb-start.sh. We should do some experimentation to determine at about what memory floor issues start to occur, and if there's any dependence on the value of CETPKG_J.

  • Status changed from New to Resolved
  • Target version set to artdaq-demo Next Release

Doing a clean build of all artdaq packages led to the following line of output:
667.89user 49.71system 4:04.09elapsed 293%CPU (0avgtext+0avgdata 785092maxresident)k
165328inputs+3376400outputs (70major+21085688minor)pagefaults 0swaps

I have added a note to Installing_and_building_the_demo, about recommended minimum specs, and I don't really think there's anything else we can do about this at this time.

#4 Updated by Eric Flumerfelt over 2 years ago

Testing with a virtual machine yields the following result: 1.5 GB of RAM is insufficient, while 2 GB works. This is for a slf6 e14:s46 build using develop (~artdaq v2_02_03).
