Sorry if this has been asked already, but is it possible to update the search text file with new prefix options while the program is running, or will it require a restart? (is that part of the base key creation?)

as far as i can see it is only loaded b4 the calculation and then not used again... so a restart would be required

Restart or no restart, it wouldn't matter all that much anyway since generating millions of keys per second and finding a matching prefix (or postfix, or middle fix or whatever) is a probability.

Stop. Add. Start. It will then start finding from a random spot. I believe it randomizes the search after every few million, or at least that's what the original vanitygen did.

He must be talking about the -i argument that specifies a text file with a list of prefixes.

If that's the case, bangbumbang is correct because
during my test, it didn't changed the queue once I've edited my text file while vanityseach is running.

"Items lost" refers to items found by the GPU that match the lookup table. It is not only  link to the number of prefixes your search, but also to the number of threads.
When you have a lookup size of 65536, each GPU thread will return 6*1024 items.
With -g 88,128 and a lookup size of 64660, the number of items found by the GPU is (in average) 6*1024*88*128*64660/65536 = 68 280 960‬ and cannot exceed 6*1024*88*128*65536.
This has to be improved.

This is very well known address with Public Key hash 0000000000000000000000000000000000000000.

Please tell me! What system is needed for your program to work (Vanity Search) 32 bit or 64 bit?

Can anyone e tell me what the bandwidth is on the xilinx board for a 9 gpu rig? What rig that's out can house more then 4x tesla v100s or T4? I cant do sunmicro best I've gotten is x4 v100 smx2 in a dl c4140
I dont want to do a cluster


I ask here instead of hardware help due to the only people I know of using this power into btc is in this thread knocking out vanitypool problems.

One of you even has custom tweaks getting 15-30% more hash on v100!  At default of 3.8-4.0 Bkps so with a full tweak one rig in theory can pull 60bkps .... the bandwidth of the v100s do I have to cluster ? Ps I have physical cards , not any instance , may cluster instance's , considering i have a hard time getting this to work in ubuntu doesnt seem likely for me.
