[sulks]  I want AMD on Windows.  Why did you have to program the niche stuff first?

The Windows OpenCL version (for AMD and NVidia) was already tested successfully. And btw, the "niche" is rather AMD, see the sever status page. E@H has 2-3x as many hosts with NVidia cards than with AMD. And I think having more than one card per host is more common with NVidia than AMD, so the card/GPU count will be even more in favor for NVidia. 

Are there any Meerkat tasks for ARM cpu's or you guys think they will take waaaay too long?

based on the messages posted early in the thread, my impression is that the BRP7 MeerKAT tasks will be for GPUs only. 
 

there is still plenty of BRP4 work for slower CPUs and ARM devices to crunch on.  

Thanks that's what I thought but was hopeful

I do find it odd I'm getting

I do find it odd I'm getting Intel GPU for radio, and not AMD.  There's more AMD power out there, and aren't they both OpenCL?

So I have to guess?  Er.... is the Intel doing BRP4 and the AMD/Nvidia doing BRP7?

not guess, but use some

not guess, but use some critical thinking. they can't send work to run BRP4/G on AMD (or Nvidia) GPU when an application for it doesn't exist.

Yes sir, sorry sir, I will try harder in future.  Spank me senseless sir.

Technical news: I see that

Technical news: I see that the iGPU v1.70 beta test has been extended to Binary Radio Pulsar Search (Arecibo, large) (BRP4G). That should help with the ARM cross-validation problem.

My UHD 620 picked up one of the early ones.

I'm shifting the BRP4

I'm shifting the BRP4 Intel_gpu app version to BRP4G, to see how validation is with the Intel CPUs. They're fast enough anyway.

Task 1341344854 is back, but

Task 1341344854 is back, but not validated yet. More will follow, but I'll let the remaining plain BRP4 tasks flush through first. My HD 530 will join in later (probably overnight).

The score for BRP4 on the UHD 620 is currently

All (883)
In progress (33)
Pending (140)
Validation inconclusive (97)
Valid (532)
Invalid (81)
Error (0)

Error (0) : nice one !

Error (0) : nice one ! ;-)

Invalid (81) : OK but ~9% ( I think < 5% is more typical )

Cheers, Mike.

I have made this letter longer than usual because I lack the time to make it shorter ...
