[Opendnssec-user] DNSSEC GPU acceleration of RSA sign operation

[Ondřej Surý]

Have you seen this?

http://svsf40.icann.org/meetings/siliconvalley2011/presentation-gpu-accelerated-rsa-13mar11-en.pdf

The repository with the code can be found here:

According to our measurements the nVidia cards don't have enough
throughput to be better than simple openssl on multicore machines. But
your experience may vary.
