New work
This weekend we will release new work. As announced earlier, first we will send out two sets of CMC WUs exclusively for Windows x64 machines. These will be submitted this evening. In parallel to that we will upload our first CMS test set of WUs to analyze eukaryotic organisms including the human genome to all systems. Please note that these WUs will require a broadband internet connection since the sizes of the genomes of these organisms are one to two orders of magnitude larger than all what we have analyzed so far. Importanly, run times can be significantly longer as well with up to 100 hrs for a single WU. Also, please watch the RAM requirements since a few WUs might end up taking up to 2.3 GB of memory.

Problem solved
I have good news for those of you whose machines failed on the CMC "monster WUs" delivered to Linux x64 systems. Tonight we most likely solved the problem which indeed has to do with memory allocation. A new parameter setting has been applied and these WUs are now out again in the wild for those who dare munching on them once again. Solving this problem was only possible with the valuable help of some of you who ran the diagnostics which we had posted to diverse forums. Thanks again for your help.

last 2 cmsearch archives
With the last 2 cmsearch runs we send and received round about 900.000 results and transfered 1 TByte of data. yoyo 4 Mar 2010 21:32:03 UTC · Comment

Current status
The entire set of CMC work units for Linux x64 machines is almost complete now and so is the current CMS bundle. We have already prepared the first eukaryotic organisms which will cause significantly more traffic during download and correspondingly require more HD storage as well. As soon as the results have been assembled (a matter of just a few days), we will normalize the client server communication intervalls such that all the problems that occurred with the last CMS work units will not reappear. We will then release a set of CMC work units for Windows x64 only plus a first test set of the eukaryotic CMS WUs for all systems to check whether it runs smoothly. If that is the case, we will fill up the server with more work. Exact dates will be announced here. Thank you all for your patience and help with the trouble shooting.

Run-time filter required
I think we will need to design a filter on the server side that, based on the run time estimates, prevents such small WUs from being sent out to clients in the future. Although we have more than 200,000 WUs left, little is computed due to the extremely heavy MySQL load that is caused by the massive connections. So, another lesson learned, I would say. These small WUs in fact can easily run on some of the (mostly idle) server CPU cores and should also finish within a few days. Michael. 23 Feb 2010 5:42:23 UTC · Comment
