3,047,909 | On compilation of the CUDA SDK, I'm getting a nvcc fatal : Unsupported gpu architecture 'compute\_20' My toolkit is 2.3 and on a shared system (i.e cant really upgrade) and the driver version is also 2.3, running on 4 Tesla C1060s
If it helps, the problem is being called in radixsort.
It appears that a few people onl... | 2010/06/15 | [

] | I believe compute\_20 is targeting Fermi hardware, which you do not have. Also, Cuda 2.3 doesn't support Fermi features or compute\_20. Try using compute\_13 instead. | You are compiling the 3.x SDK with a 2.3 Toolkit, that won't work since as you've now seen compute\_20 is not supported.
The simplest solution is to either upgrade your Toolkit or downgrade your SDK. You could try changing the makefile (common.mk in C/common) on Linux or changing the Build Properties on Windows to sel... |
16,086,851 | In spreadsheet cell B1, the value is -1200.
I want cell B2 to copy the value of B1 and limit (validate?) it to no less than -800.
I'm using google docs but can also use excel if those functions are not available in google docs.
Edit:
If B1 has the value of 2000, B2 should have the value of 2000.

] | Excel formula would be pretty easy, probably similar in Google Spreadsheets:
In B2, put this formula:
`=If(B1<-800,-800,B1)`
This is saying:
If the value in B1 is *less than* -800, then put the value "-800". Otherwise, use the value from B1. This effectively puts a "floor" or a lower bound on the formula. | You don't need any maths here. I'm using Excel but I think it is pretty similar in Google.
Suppose that B3 holds floor, no constants in formulae :-)
B2 => =if( b1 > $b$3; b1; $b$3)
b3 position is fixed so you can copy the expression |
