Hi, this is quite strange.
Can you give me some detail about your hardware configuration?
Do you have the same issue also using the openssl engine autoloading?
NOTE: I've looked at that you are trying to run the test speed using the
aes-cbc, be carefull while evaluating the performance of that test.
If you want you can write directly to my email address ( using the italian
language ;-) ), you could find it looking at the source code.

Now I am at home, and I don't exactly remember the whole machine
configuration, just the GPU that it's a GTX260. Tomorrow morning I'll
send you the remaining hardware information. I'll try the autoloading as
well. I'm a CUDA newbie, so it's pretty difficult for me to find a
solution looking at the code.

Hi,
here some more info about my hardware configuration:
- Intel Core 2 Quad Q9400;
- 4GB Ram
- GeForce GTX260, driver version 190.53
I've found incompatibilities with CUDA >3.0 and the installed drivers, so I've
downgraded CUDA to version 2.3 and managed to compile the engine.
Regarding the reported error, I've managed to load the engine and perform some
encryptions in the following ways:
- loading the engine from the OpenSSL prompt WITHOUT the -t dynamic flag;
- specifying an alternative configuration path (with the same setting described
in the wiki) setting the OPENSSL_CONF env variable.
Anyway the engine still randomly crashes or stops working. For example, using
the custom conf file and getting two consecutive times the engine list, the
second time I get this error and the engine becomes unusable:
OpenSSL> engine -t
Successfully found a device supporting CUDA (CUDART_VERSION 2030).
Using pinned memory: cudaHostAllocDefault.
The current buffer size is 8388608.

First, it appear that there is an issue while using the openssl command line.
You could bypass this by using directly the openssl command (and adding the
options that you need on the command line) like I do in usage example in the
wiki (normally I use the engine in this manner).
Second, I think that your system environment isn't setup correctly, you may
also consider a fresh install for your test (for example fedora 11 is a three
years old distribution, driver 190.53 should not be used with cuda 3.0, last
but not least: gcc 3.4? I know that fedora 11 use gcc 4.4 that has problem with
cuda 3.0 but this leaves me surprised).
Are you using the patched version of openssl?
Have you tried other cuda software on that system? They are working correctly?
And last, I think to known where are located the pc that you are using...you
are writing from Politecnico di Torino, right? ;-)
Sicuro di non voler una consulenza sul posto? Se vuoi mi puoi contattare
direttamente al mio indirizzo email, lo trovi all'interno dei sorgenti
dell'engine.
