HPC Parallelization & Advanced Scheduling
High-Performance Communication Layers Engineered for the Next Era of Computing
At Qvanta® LLC, we design, refine, and optimize OpenSHMEM-based communication and execution layers for high-performance computing systems. Our work accelerates large-scale scientific workloads, defense-grade simulations, secure AI compute, and quantum-inspired algorithms by enabling ultra-low-latency, one-sided communication and deterministic parallel execution across thousands of nodes.
We combine deep expertise in parallel architectures, distributed memory models, RDMA-accelerated fabrics, GPU–GPU communication, and schedulers capable of operating at exascale.
Our goal is simple: deliver HPC performance that is predictable, scalable, fault-tolerant, and secure by design.
WHAT WE DEVELOP
OpenSHMEM Extensions & Optimized Implementations
- •Custom high-performance OpenSHMEM layers for InfiniBand, Slingshot, Omni-Path
- •GPU-accelerated OpenSHMEM (NVSHMEM-style) for multi-GPU clusters
- •Symmetric heap optimizations for large distributed arrays
- •Zero-copy remote memory access pipelines for scientific workloads
- •Low-latency RDMA tuning for put/get, atomics, and remote collectives
- •Memory ordering, fencing, and consistency enhancements for mission-critical workloads
Code Example
"text-gray-500">// Example: symmetric heap + one-sided put/get
#include <shmem.h>
#include <stdio.h>
#define N 1024
long *A; "text-gray-500">// symmetric array
int main(void) {
shmem_init();
int me = shmem_my_pe();
int npes = shmem_n_pes();
A = shmem_malloc(N * sizeof(long));
"text-gray-500">// Initialize local data
for (int i = 0; i < N; i++)
A[i] = me;
int dst = (me + 1) % npes; "text-gray-500">// neighbor PE
"text-gray-500">// Zero-copy remote write into dst's symmetric heap
shmem_putmem(A, A, N * sizeof(long), dst);
shmem_quiet(); "text-gray-500">// ensure RDMA completion
shmem_barrier_all(); "text-gray-500">// deterministic sync
if (me == 0)
printf("OpenSHMEM layer ready across %d PEs\n", npes);
shmem_free(A);
shmem_finalize();
return 0;
