Re: [climateprediction.net] Linux work *perhaps* coming up in quantity

On January 19, the upload server filled its disk again. This time the reason is that the tape drive system went down, to which data were streamed off of the upload server. To make matters worse, when the tape drive system will be back up, for some unstated reason, it won't have enough space for the ...

Re: [climateprediction.net] Linux work *perhaps* coming up in quantity

Update from CPDN meeting 16/1/23 Upload http connections will be increased over the next 2 days back to the previous maximum of 300 simultaneous connections as most of the previous uploaded data has now been moved off. The 'grace period' for return of tasks has been changed from 'nothing' to 30 day...

Re: [climateprediction.net] Linux work *perhaps* coming up in quantity

The upload server outage continues — sort of — for another few days. And yes, the server remains seriously undersized. Hello All, Brief update on status. The upload server is back running and we are currently in the process of transferring ~24TB of built up project results from that system to the an...

Re: [climateprediction.net] Linux work *perhaps* coming up in quantity

I realize that the server has to catch up, but as poor as its performance is now, this will take a long while or may even never recover entirely. That's just my own pessimistic opinion, not fact, based on seeing server availability going down (and finally vanishing entirely) during the few hours ye...

It's not. xii5ku could upload some bits a few hours ago, but now 100% of the transfer attempts fail. parsnip could upload, but has an increasing rate of failed transfers too now and therefore shut everything off again (due to disk space constraints).

Re: [climateprediction.net] Request to volunteers to please enable: 'Leave non-GPU tasks in memory'

The main reason (but not the only one) for this notice is this: If an OpenIFS task (of the current application version and workunit batches) is suspended to disk too often, it will take more disk space for its state files than allowed as per the corresponding workunit property. At that point, the bo...

A proposed fix is still in the making . Just out of a meeting with CPDN. They understand what the problem is.

Re: Low power video card

No. There certainly is no 3D acceleration hardware in it, and the kernel driver provides just a simple frame buffer device. The AST2510 has got an ARM CPU which runs the BMC firmware. But even if you rewrote that firmware so that you can run your own stuff on this CPU, this embedded computer would c...

Floppy disk drives are examples of block storage devices.
Perhaps they are migrating from 5.25" to 3.5" floppies now.

The usual reason for this is a series of error returns from the client. It will clear only if the client then delivers a few successful results (or just one?), or if the server admin manually removes this block. Due to the suspend bug of the earlier version of the application I had a series of failu...
