This workload may have been out of its 4gb 32-bit memory space limit but my machine still had 18GB free when this aborted. Ralphie is taking dumps on my machine. There are a number on this Win10 machine. https://ralph.bakerlab.org/show_host_detail.php?hostid=35400 started at 2016- 2- 5 23:31:34, and took a dump 40 min later. 02/06/16 00:19:17 Task ID 3733284 Name 02_2016_3r8b_backrub_design_20294_68_1 Workunit 3289094 minirosetta_3.71_windows_x86_64.exe https://ralph.bakerlab.org/result.php?resultid=3733284 |

dekim said: Yes, I'm running a test of a new type of job that runs small perturbations of the protein backbone and then does a round of design. The design protocol can use a lot of memory. I realize that this will be problematic and will see if we can distribute these jobs to high memory machines. It's time to pass to 64 bit native app?? :-) |

dekim said: I don't think 64-bit needs to be a requirement. I am not sure how much benefit, performance wise, it would offer either. I have guessed 10% or 20% ... I think. I probably should build a couple 32-bit variants and measure results on same hardware and compiler. It is just a memory leak or a memory management integration problem with the new program code. 4gb is a lot of memory space. BOINCTASKS says the current Rosetta Windows 32-bit is taking 460mb of memory space. I doubt the new changes mean the memory requirement has gone up 10x. If they cannot make Rosetta work in 32-bit, then they will have to look at all the issues that are building pressure to improve their TASK distribution of jobs. If they cannot get it to work in 4gb (32-bits): - 32-bit machines will not work for that version. - 64-bit machines with <small>gb of memory will not work for that version. - 64-bit machines with just enough memory PLUS disk paging space will work BUT with <many times> slow down .... complete the same work .... but will burn out the disk head seek mechanism faster ... which I would not run. If my disk light goes on solid, I find out why and stop running the problem program. I just did that with the Linux tracker-miner (I shut down the indexer). |

This is the message on my machine 08/02/2016 23:11:14 | ralph@home | Rosetta Mini needs 7629.39 MB RAM but only 7356.70 MB is available for use. If this will be the future, i need to buy some ram modules :-P |
