    <p>I have programmed CUDA code.</p> <pre><code>unsigned long mask_buffer; int s; off_t p, for(p=0;p!=5000;p++) { for(s=start;s!=end;s++) { ref_off = *(((unsigned int*)(idx_base)) + p); if((int)(first_indexes[s-start_sequence] % 8 - ref_off % 8) &lt; 0) { int shamt2 = (ref_off % 8 - first_indexes[s-start_sequence] % 8); mask_buffer = *((unsigned long *)(msk_base + (ref_off - first_indexes[s-start_sequence])/8)) &gt;&gt; shamt2; if( ( (*(unsigned long *)(seqmaskc + 16 * (s-start_sequence))) ^ mask_buffer ) &lt;&lt; shamt2) continue; } else if((int)(first_indexes[s-start_sequence] % 8 - ref_off % 8) == 0) { mask_buffer = *((unsigned long *)(msk_base + (ref_off)/8)); if( (*(unsigned long *)(seqmaskc + 16 * (s-start_sequence)) ^ mask_buffer)) continue; } else { int shamt2 = 8 - (first_indexes[s-start_sequence] % 8 - ref_off % 8); mask_buffer = *((unsigned long *)(msk_base + (ref_off/8- first_indexes[s-start_sequence]/8) - 1)) &gt;&gt; shamt2; if( ( (*(unsigned long *)(seqmaskc + 16 * (s-start_sequence))) ^ mask_buffer ) &lt;&lt; shamt2) continue; } int shamt = (ref_off % 4 - first_indexes[s-start_sequence] % 4) * 2; memcpy(reference_blk, ref_base + ref_off / 4 - first_indexes[s-start_sequence] / 4, sequence_bytes); for (rp = last_rp ; rp != (unsigned long *) reference_blk ; rp--) { unsigned long tmp = ((*rp) &amp; ((1 &lt;&lt; shamt) - 1)) &lt;&lt; (8 * sizeof(unsigned long) - shamt); *rp = (*rp &gt;&gt; shamt) | shifted_in; shifted_in = tmp; } *rp = (*rp &gt;&gt; shamt) | shifted_in; if (sequence_length &amp; 0x3) reference_blk[sequence_length &gt;&gt; 2] &amp;= (1 &lt;&lt; ((sequence_length &amp; 0x3) &lt;&lt; 1)) - 1; for ( i = sequence_length &gt;&gt; 2 ; i &amp; (SEQUENCE_ALIGN - 1) ; i++ ) reference_blk[i] = 0; //-- instead of memcmp --// int v = 0; char *p1 = (char *)sequence; char *p2 = (char *)reference_blk; int tmp_asd = sequence_bytes; while(tmp_asd!=0) { v = *(p1++) - *(p2++); if(v!=0) break; tmp_asd--; } if(v == 0) { mat_count[s - (int)start_sequence]++; /* Maintain count */ mat_position[s - (int)start_sequence] = ref_off-first_indexes[s-start_sequence]; /* Record latest position */ } } } </code></pre> <p>This for loop is main function of my code. But the problem is that variable "p" is never increased over 5 or 6. I have GT530 in my computer and my CUDA Driver Version and Runtime Version are also 4.0. What is problem in this code???</p>

    1. COCould you include the full code, or at least the part of the code with types in it?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
