Accelerating SQL query execution with GPUs is a central focus in database research. While prior systems have achieved notable speedups by offloading relational operators, the acceleration of the wide range of scalar functions that are supported by analytical engines remains unaddressed. Our analysis reveals that many scalar functions incur substantial computational overhead and often constitute the primary bottleneck in analytical queries on CPUs. Thisobservation motivates a systematic exploration of the opportunities and challenges in accelerating scalar functions on GPUs.Unlike relational operators, which are few in number and standardized, production databases support hundreds of scalar functions. The absence of a standardized specification, combined with this diversity, renders manual GPU porting infeasible. To address this, we present an LLVM-MLIR-based compiler toolchain that automatically translates the CPU-based implementations of scalar functions from production databases into efficient GPU kernels, while preserving their original semantics. Our approach lifts scalar functions to a high-level intermediate representation, applies resource-optimizing transformations, and generates GPU assembly code, supporting all relevant data types, parameters, and database context variables.As existing benchmarks do not sufficiently stress test scalar functions in analytical queries, we introduce a variant of TPC-H that utilizes scalar functions while preserving the original query intent. Integrating our GPU kernels into a state-of-the-art GPU data base system, we demonstrate substantial performance gains over a leading CPU database that uses slightly more expensive hardware: 7.6× on enhanced TPC-H and 6.4× on production queries, furtherwidening the gap between GPU and CPU databases. The generated kernels deliver performance comparable to hand-optimized GPU implementations, establishing our approach as a scalable and practical solution for accelerating scalar functions on GPUs.

I wanted to share my experience with AscendEX and see whether anyone else has gone through something similar recently. I’ve used AscendEX on and off for years and never had a serious issue before. However, my latest withdrawal has now been stuck for more than a week in “Initiating” status. The most concerning part is that there is still no TXID at all. The withdrawal never appears to have reached the blockchain. The funds were removed from my available balance and are effectively locked, but there is no transaction hash, no rejection notice, and no explanation. I contacted support through every available channel - Support ticket system, email and telegram At first I received generic responses telling me to wait. After asking for actual information about the cause of the delay, things became even more concerning. When I publicly asked about my case in the AscendEX Telegram group, my message was removed and I was banned from the group shortly afterward. Since then, the Telegram admins who were previously responding have stopped replying entirely. My support ticket remains unresolved, and emails either receive no response or no meaningful information. Nobody has been able to explain: Why the withdrawal is stuck Why no TXID exists Whether there is a wallet issue Whether withdrawals are being manually reviewed When the problem is expected to be resolved I understand that exchanges can experience technical problems. What worries me is the complete lack of transparency. If there is a technical issue, just say so. If there is a wallet maintenance issue, say so. If there is a backlog, communicate it. Instead, I have been left with funds locked for over a week and no meaningful answers. While researching the issue, I found multiple recent reports from users mentioning withdrawals remaining in “Initiating” status for extended periods. That makes me wonder whether this is an isolated case or part of a larger problem. I’d appreciate hearing from anyone who has recently experienced withdrawals stuck in “Initiating”, missing TXIDs for extended periods Most importantly: Did your withdrawal eventually go through, or were your funds returned? At this point I’m trying to determine whether this is a temporary operational issue or whether I should be seriously concerned about the safety and accessibility of funds on the platform. Any information from current or former AscendEX users would be greatly appreciated. submitted by /u/itsckomi [link] [Kommentare]
