Therefore lowering the price from $5k on the table will really improve their "james' value ratio" [don't laugh, that is a very good indicator!], making it highly comparable with the Titans, especially as we switch to higher and higher exponents, more memory (and especially ECC memory!) for larger FFTs becomes a must (and it should also count toward the score, but that is a different story).

I was just speaking with chasall about this. I have a decent selection of AMD cards I can provide at least an initial seed of benchmarks to make this happen if someone tells me what we need.

James is the guy you have to talk to.
With chalsall you talk about Barbadian Rum and swimming pools

The NVIDIA side is already messy enough, but I have no objections to including AMD data as well. I didn't even know clLucas existed. If people want to send me benchmark data I can start including it in the chart, but nobody has ever done so therefore I have no data to present.

The pricing data is pulled from a local computer retail store so only is updated regularly for items currently being sold. Also please note that all prices are in Canadian dollars which can vary from +0% to +50% on the US dollar. My price source doesn't happen to carry any K80 right now, but a quick search for other Canadian prices for K80 gave me $5999, $5999, $6295, $6400 as the best 4 prices I could find, so listing $5000 on the table is actually a bit lower than it should be.

For now the same benchmark used for CudaLucas would be great:

The database seems to not be in sync anymore as the date for the most recent data is "22 Feb 2016"

James Heinrich · 2016-02-26, 16:49

Thanks. The data feed from PrimeNet had an unexpectedly-large dump of data on 2016-Feb-23, more than triple the typical daily amount of data. The XML file itself was 254MB, so PHP ran out of its allocated 256MB trying to process it.

I'm working to manually import the data from the 2016-Feb-23, and once that's done the subsequent days shouldn't be a problem. I'm currently running into some timeout issues where it's taking longer than PHP will let a single script run for, but I'll get through it eventually. I'll update when it's fixed.

That would be the skipped-TF results of mine that Madpoo imported :)

How was I to know 394,767 result lines would cause such trouble! Doesn't AirSquirrels do that like every day? ;)

23-Feb finished, finally

Code:

Inserted (511,782 results after 1,953 seconds)
Done in 2,206 seconds

James Heinrich · 2016-02-26, 18:41

Data sync is now up-to-date.

For comparison:

Code:

23-Feb = Inserted (511,782 results after 1,953 seconds); Done in 2,206 seconds
24-Feb = Inserted ( 83,524 results after   644 seconds); Done in   885 seconds
25-Feb = Inserted ( 90,642 results after   510 seconds); Done in   751 seconds
