Now change to unroll 12.

Unroll 12 worked, http://setiathome.berkeley.edu/result.php?resultid=3880847394, but I will run couple more tasks to be sure.

After that, if no problems, should I increase it to 14?

Yes.
After a few completed task try unroll 16.
Then we change ffa_block values.

Hey Mike, maybe you know the answer to this while we're on the topic of configuring GPUs. I asked what commands I should use for a GT 730 here:

http://setiathome.berkeley.edu/forum_thread.php?id=75996&postid=1618100

Is processing one task optimal? My 550 Ti does two fastest.

It's the newer 730 with specs as on far right:

http://www.geforce.com/hardware/desktop-gpus/geforce-gt-730/specifications

Thanks

I need to know how many CU`s the 730 has.
One instance on this card should be faster.

It has two CU

Something to start with.
-use_sleep -unroll 4 -oclfft_plan 256 16 512.
Maybe some further tuning possible.
But i want to see a few results first.

Ok, I'm using this. I installed the GT 730 tonight and am starting to process some tasks. I freed one core on the i3 2100 (dual core with hyper-threading).

What I can tell so far in MSI Afterburner is that it is stable at 75% GPU usage

Then we change ffa_block values.

Ok, unroll 16 works fine.

So, running now -ffa_block 2830 -ffa_block_fetch 2830

How much do I increase those values?

Try -ffa_block 5660 -ffa_block_fetch 2830.
If you experience lags go back to unroll 14.
You might end up with unroll 14 but bigger ffa_block values.

Thanks Mike.

Could You provide more -ffa values to test (and -unroll) so I don't have to bother You every time when I need to change values to test my host.

Are my switches for the 730 looking ok so far? GPU usage is stable in the range of 75-80% I left it processing overnight.

O.K. Here a few values to test.

-ffa_block 5660 -ffa_block_fetch 5660
-ffa_block 6144 -ffa_block_fetch 3072
-ffa_block 6144 -ffa_block_fetch 6144
-ffa_block 8192 -ffa_block_fetch 4096

First try those with -unroll 16.
If one doesn`t work try with -unroll 14 or -unroll 12.

Your 730 only finnished 2 AP`s and both were overflows.
Let it run, i will check back tomorrow.

Oh I thought the commands affected multibeam as well. I'll let you know about the 550 Ti once I get back to Ottawa from break :)

---

Are there any further changes I should do to the 730? I have to make the change before I leave on Sunday. Thanks and happy new year :D

Do you think my 550 Ti machine is doing ok as well? I've haven't tinkered with it in a while. One core on an E6600 is free and the 550 Ti crunches two tasks.

I believe it's using this:

-unroll 10 -ffa_block 6144 -ffa_block_fetch 1536 -hp

Are those settings still current? The -oclFFT_plan switch is new to me. Could that be added? And finally, does ffa_block and fetch not apply to the 730?

Thanks for all your help, Mike.

It could do better.
First you are suffering from high CPU usage, this requires -use_sleep switch.
-oclfft_plan is a new method to optimze fft kernel planning.
Read the read me`s.

Try

-use_sleep -unroll 10 -oclfft_plan 256 16 256 -ffa_block 2830 -ffa_block_fetch 2830 -tune 1 64 4 1 -tune 2 64 4 1.
Maybe unroll 12 is possible on the 550Ti.

On the 730 ffa_block values wont give much improvement.
We can still add it after you finnished a couple units.

Hey Mike, I'm back in Ottawa, looking at the 550 Ti's command line:

-unroll 4 -ffa_block 2048 -ffa_block_fetch 1024 -hp

Whatever I said above was wrong. I'm going to put the line you suggested in.

I've a question for you 750ti users.

I know they're small and importantly they're bus powered. Do you think I could stuff one (or a couple) in a Dell PowerEdge 1950?

JarrettH...

What is your final configuration of the command line for that GT 730? Just asking as there maybe other that could benefit from what you decided on the final config.

I'm still using

-use_sleep -unroll 4 -oclfft_plan 256 16 512

on the 730. I don't think it has much room for improvement with two compute units, and I'm fairly sure one task at a time is best.

It's this MSI one:

http://www.msi.com/product/vga/N730K-1GD5LPOC.html

Small core clock boost with fast 1 gb of memory

Hey Mike, do you think the run time on my 550 Ti is any faster with those commands?

Its not bad but you have big variation in processing time.
This is probably related to your 2 core CPU.

Increase ffa_block to 8192 and ffa_block_fetch to 4096.

One (or a couple) of these might fit. I just put one into an OptiPlex 745 small form factor and it fits and runs fine.

Well hello! That looks as if it'll do the job spiffingly! I'll have to double check the thickness of the heatsink & fan but that could be a winner. AND they sell it through the UK store.

Assuming, as was mentioned in the other thread, that it's a x16 slot...
