issue with CUD-BLASTP

Dear Sir/Madam,


I have installed CUDA-BLASTP on C2050.It is giving me an Error:
"Bad address
Error opening matrix file (null) for reading"

while i am running with following query file and dataset:

./CUDA-BLASTP -i ./data/raimondii_contigs.fasta -d ./data/DB_sorted.fasta


and i am using BLOSUM62 as a matrix file which is already present in package.

And getting the error:"Error happened when the number of GPUs is 0"
while i am running CUDABLASTP with a part of dataset taking as a query file and dataset is same.
above mentioned error is comming from file "CUDA_Blast.cu" included in package.
else
{
printf("Error happened when the number of GPUs is %d\n", localGPU_N);
exit(0);
}


please send me solution of following error as soon as possible.



Thanks & Regards,
Abhinav
