server.bat
Code:
kangaro.exe -w save.work -wi 300 -d 28 -s input.txt

client.bat
Code:
kangaro.exe -nt 36000 -t 0 -gpu -gpuId 0,1,2,3 -g 880,256,880,256,880,256,880,256 -c {MYserverIP} input.txt

Many thanks
I did`t change constant, so can`t say nothing about this.
server.bat is correct
client.bat is not correct because v100 have 80 SM, so you need set grid like 160,256 or 160,128
DP bit size you should set as you wish, somebody set it to 25, somebody to 31. It is only your choice.
Less DP  = more memory usage, affect gpu perfomance
More DP = more time to find DP


Many thanks for the reply and explanation "-d"
Unfortunately, I have to watch the server, because it just ends every hour for no reason. What could be the reason?
Can I resume working clients (who are still waiting for the server to reappear) with the -i save.work option? Because the resumption of the server theoretically looks like it continued where it ended and the clients act as if nothing happened :-)
