V100的AI训练能力
V100在AI训练中的能力已经被验证了，它是超级计算机Summit的计算核心，是OpenAI大模型训练最早使用的显卡。标志着人工智能新突破的GPT-3就是用V100的集群训练的。虽然已经面世8年，很多V100已经开始退役，但它仍然是算力强大的GPU。
密码破解场景测试
众所周知破解密码需要使用暴力尝试的方法，需要很大的算力，在这个场景V100的能力怎么样呢？大家也知道hashcat是进行hash解密效率最高的软件，我们就通过在一个装有四张V100显卡的服务器上运行hashcat的benchmark来展示V100计算hash（破解密码）的能力。这个能力已经被MyPassRecovery用在了自己的在线服务上，构建了强大的算力基础设施。这是MyPassRecovery比其他密码恢复软件有优势的地方。
测试环境
- GPU: 4 x Tesla V100-SXM2-16GB
- 内存: 每张卡 16GB
- CUDA版本: 12.8
- Hashcat版本: v6.2.5
- 测试模式: Benchmark with optimized kernel
Benchmark测试结果
原始输出
# 在此处粘贴hashcat -b命令的完整输出
$ hashcat -b
hashcat (v6.2.5) starting in benchmark mode
Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
* Device #1: WARNING! Kernel exec timeout is not disabled.
This may cause "CL_OUT_OF_RESOURCES" or related errors.
To disable the timeout, see: https://hashcat.net/q/timeoutpatch

运行状态监控
测试运行了10分钟，显卡的负载并不大，温度也不高。通过nvidia-smi监控显示：
- GPU利用率适中
- 温度控制良好
- 功耗稳定
性能分析
从测试结果可以看出：
-
基础哈希算法表现优异：V100在MD5、SHA、NTLM等基础哈希算法上表现出色，特别是NTLM达到了402.5 GH/s的惊人速度。
-
迭代哈希算法性能合理：对于bcrypt、scrypt等需要大量迭代的算法，性能符合预期，这类算法本身就是为了抵抗暴力破解而设计的。
-
性价比优势：V100的性能与RTX 2080 Ti相当，但在二手市场价格更有优势，对于需要大规模密码恢复或安全测试的场景，V100是一个性价比很高的选择。
总结
虽然V100已经推出8年，但其强大的计算能力在密码破解场景下依然表现出色。对于企业级密码恢复服务、安全审计、渗透测试等应用场景，V100仍然是一个值得考虑的选择。特别是在二手市场上，V100的性价比优势更加明显，为构建高性能密码破解集群提供了经济实惠的方案。
