I will report back when I have that (tomorrow). > I checked and the only possible error type that is related is "CL_INVALID_PROGRAM_EXECUTABLE", so whenever the program is invalid we would get that error. The rest of the error codes are about invalid kernel, context, dimensions, etc. Today I modified the program that creates the kernel so that it passes the appropriate number/type of arguments for the blowfish kernel. Then when I tried to copy the assembly generated fromt he kernel, I realized that it might be wrong. Could somebody please take a look at this ISA? (I attached it to the mail) All it does is loading dwords, writing something to the LDS and do a very little computation. Surely blowfish is more complicated than this. Might the ISA be wrong? All the ds_write calls and no reads is a bad sign. The ISA of DES (which also uses DS instructions) looks much better, maybe I should try to use that instead.
