I aborted 2 in the last week that seemed to run forever.

I have been seeing a raft of computation errors on several systems - mostly running Windows XP and 9800GT cards. This seems to be a revisit of a problem which plagued the GPUGrid applications a year ago for me. Since it has affected ALL of my systems running that combination, and I have NOT encountered similar problems with three other BOINC projects which utilize the same GPU on the same systems (SETI, Dnetc, Collatz), for now, rather than simply 'shoulder shrug' and try, try again, I am backing off of GPUGrid for now.

I would hope that there would be some responsive comment on this out here, but historically, what I have seen here is either denial (it must be my hardware or software -- even though other BOINC GPU apps complete properly), or non-response. Then, perhaps in a week or two, I will try again, and some unacknowleged change will have been made and all will be well again.

I'm getting over a 50% error rate across a several quads. The majority of the cards are GTS-250s, but there is a GTX-275 and a couple 8800GTs thrown in also. Same machines also do either DNETC or Collatz w/o issues.

One of the worst is crunch30.

crunch35 has both a GTS-250 and a GTX-275.

Can anyone provide any insight to this?

UPDATE: Worse than I thought... 7 pages of valid results, 18 pages of errors.

As I noted before -- the normal scenario here is when problems like this crop up -- there is a real limit to the amount of response we can expect...

I just aborted another one that ran on to long. Between the probs others are having and the ones I am experiencing I am pulling out until the bad WU's clear the catch.

Sorry, I already moved off, be back later. Trying to run SETI since 1999 has made me gun shy (crazy). So many projects so little time. Thanks for the response, I generally get criticism on other sites so I don't post.

I got an error on a TONI_CAPBIND as well, like many others. I can't see the original error in this thread any longer, as the WU is already purged, but here is my stderr:
