I have four computers set up for WCG. All four are saying "Waiting to contact project servers". Is this due to the hardware failure or should I log out/log back in to WCG on each computer to get them talking to WCG servers again?

Be gentle Ralf - it looks like Craig is a new(ish) member here, and hasn't had a whole lot of experience seeing WCG working at 'full tilt' (as the 'longer in the tooth' members have seen when it had IBM's resources behind it).

So, yes Craig - it's all down to the BOINC servers not currently running - due to the hardware issues Krembil are working on.

P.S.., I'd personally recommend changing your 'handle name', to one that doesn't actually include your e-mail address, as there are 'bots' constantly trawling the Internet, looking for e-mail addresses that they can harvest in order to spam you.

As requested by Grumpy, here goes:
"I have concluded from web information that you are the new owners of The World Community Grid (WCG). I would therefore urge you to take an interest in this significant tool that you possess. Not only because I believe it is essential to the continuation of Dr Jurisca’s research but also that this massive computer capability fits your mission to Invent and Deliver Tomorrow's Care and to strive to deliver a healthier world.
I understand from your releases to the public that you already know the capabilities of WCG. However, I might point out some of the limitations of parallel processing. It can perform the same calculation in parallel on a massive database as multiple “If – Then” calculations. However, the multiple resultant “Thens” cannot be returned as new “Ifs” to the system without being returned to the researcher for evaluation. For instance, it can calculate the structure of all the known genes in all the different organisms within the GI track, but the resultant “Thens” (structures) must be returned to the researcher. This is valuable if one believes that when you know the structure of each gene, you can determine its product. Knowing that, you might evaluate the effect of the genome on diseases such as diabetes and ulcerative colitis.
Because of the nature of the grid and the voluntary nature of when the calculations are performed, the information is not available in real time (like batch processing in accounting). Thus, for instance WCG cannot be used in real time weather predictions.
It might help to know my opinion of the nature of the group of people donating time to WCG. They seem to be relatively intelligent people who are interested in computers and what computers can do. They have chosen WCG for the wide variety of interesting projects offered. I believe that, at least subliminally, they are aware that sitting in front of their computers and watching them crunch on a project is not actually doing science but contributing to it. I believe that as a group they would want to continue to contribute to WCG to support their interest. I think that what they would value most, in return for their support, is communication.
Therefore, I would urge you to take ownership of your new acquisition, to understand and to throw your weight behind it with emphasis and to recognize the need for WCG within your mission.
You could divert some talent within your organization to help Dr Jurisca draw up a business plan to support WCG as an entity including “communication” such as workload statistics and updates from the researchers.
You could work with your foundation to ease fiscal contributions to support WCG.
You could publicize WCG within your organization and among your contacts. It is a very interesting concept.
I do not believe that these moves would be cost prohibitive in an era of tight budgets.
I would ask you to check with Dr Jurisca as to the accuracy of these statements."

Probably pointless and rhetorical at this stage, but why didn't Krembil take over sponsorship and contract with IBM to operate and maintain the original setup? Seems at least short-term it could have worked to everyone's advantage while a longer-term migration plan was put together. It appears from the outside that Krembil tried to do too much with too little while re-engineering the hardware and software systems to run WCG with far less than IBM's skillset.

Well, that's one of the NOT SO SIMPLE points in this whole issue.
According to Dr. Jurisica, "Krembil", despite relentlessly plastering their name/logo all over the place, is actually not involved with WCG at all...
