These several days I often get "failed" messages, some times it is "RequestAssignment() failed", some times "Received assignment ( IDLE 0-0)".This maybe because there is no task temporarily.But why there are so many "SubmitResults() failed" messages.I'm really sick about it.

Suggested ratio for (max a)/(max b) =        1.502
Caution -- siever input uses (width a) = 2*(max a) and range for b.
This is because a can be negative but b must be positive.

There are two causes of "IDLE" assignments. Although, except in the past few days when the project manager has been away and allowed the assignment queue to become depleted, it is rare that there is nothing available to be assigned, you can also receive "IDLE" assignments because you are "blacklisted" for failure to properly return results. Given your log excerpts, I think that this is likely to be the cause. As to the cause of the communications problem, I have insufficient information.

I would like to assign you to another server where I can closely monitor the traffic.

I will contact you via e-mail from your registration records.
